Rajendra I (/rɑːdʒeɪndrə/; Middle Tamil: Rājēntira Cōḻaṉ; Old Malay: Raja Chulan^[5][6][7]; 26 July 971 CE – 1044 CE), often referred to as Rajendra the Great, Gangaikonda Cholan (Middle Tamil: Kaṅkaikoṇṭa Cōḻaṉ; lit. 'Bringer of the Ganges'), and Kadaram Kondan (Middle Tamil: Kaṭāram Koṇṭāṉ; lit. 'Conqueror of Kedah'), was a Chola Emperor who reigned from 1014 and 1044 CE. He was born in Thanjavur to Rajaraja I. His queen was Vanavan Mahadevi and he assumed royal power as co-regent with his father in 1012 until his father died in 1014, when Rajendra ascended to the Chola throne.

During his reign, the Chola Empire reached its zenith in the Indian subcontinent; it extended its reach via trade and conquest across the Indian Ocean, making Rajendra one of only a few Indian monarchs who conquered territory beyond South Asia.^[8][9][10]

In his early years, Rajendra was involved in the Chola Army, with which he fought in several campaigns against the Western Chalukyas and the rulers of Anuradhapura, earning him his first victories. He quelled rebellions in the Chera and Pandiya vassal states, and in Sri Lanka. As Emperor, Rajendra completed the conquest of Anuradhapura and brought a large portion of Sri Lanka under imperial rule.^[11] Rajendra expanded Chola rule by defeating the kingdoms of Kalinga and Vengai, and subduing the islands of Laccadives and the Maldives, which he renamed Munnir Palantivu Pannirayiram ("Twelve Thousand Islands and the Ocean Where Three Waters Meet"). These islands were later used as strategic naval bases. During his South-East Asia campaign, he annexed Srivijaya, Kedah, Tambralinga and Pegu, achieving imperial dominance in the region and strengthening Indian influence in Southeast Asia.

Rajendra conducted a war against the Pala dynasty and captured a great deal of wealth, which he used to build the city of Gangaikondacholapuram, the capital of the Chola Empire, and one of the centers of trade and commerce in the empire for several centuries.^[8] The city was remarkable for its artificial lake, extensive fortifications, moats surrounding the imperial palace, and the Brihadisvara Temple. Rajendra was a follower of Shaivism but welcomed Buddhism and built several stupas across South-East Asia and South India.

New forms of trade emerged during Rajendra's reign such as the commercial system called "emporia," this was after the Chola's had gained control of Strait of Malacca and several other coastal areas.^[12] Emporia refers to exporting goods according to their demand, arose, making trade within the Empire profitable and helped maintain the Chola military. The Khmer Empire was a major ally and trading partner, and helped the Cholas expand their networks as far as Song China. This link allowed Rajendra to incorporate Chinese vessels into the Chola military. These networks also extended west; the Cholas engaged in the spice trade with Arabia, North Africa, Anatolia and Turkic peoples.

Rajendra Chola I was succeeded by his son Rajadhiraja I, who ruled from 1044 to 1054.^[13]

The exact birth date of Rajendra I is unknown; it is speculated he was born around 971 CE.^[14] He was the son of Rajaraja I and queen Vanathi, who is also called Thiripuvāna Mādēviyār. Rajendra had a younger brother named Araiyan Rajarajan, who became a commanding general of a Chola army, and at least three sisters; the younger sister was Kundavai (not to be confused with Kundavai Pirattiyar), the queen of Chalukya-Vimaladitya; and a daughter called Mahadevi. Other significant members of the royal household include queen mother Dantisakti Vitanki—alias Lokamahadevi. The nakshatra of Rajendra's birth was Thiruvathirai (Ardra).^[15]

Rajendra was declared heir apparent and formally associated with his father in the administration of the Chola Empire in the final years of his father's reign (1012–1014). ^[9] In 1018, Rajendra appointed his son Rajadhiraja as heir apparent or co-regent to the Chola throne, which Rajadhiraja occupied from 1018 to 1044.^[16]

On his father's behalf Rajaraja I, Rajendra I started his wars on the Indian mainland when he was a co-regent for his father in an expedition in 1012 with the capture of Aduthurai in modern-day central Tamil Nadu and Vanavasi in western Tamil Nadu. He then directed his attention to Kollipaakkai in northern Andhra Pradesh and captured it in 1013.

In 1014, Rajendra led a war against the Irratiapaadi ElaraIiakam in northern Karnataka and southern Maharashtra. He also captured its capital city Mannaikadakkam or Maleked on behalf of his father, which met this reversal after its initial capture by Rajaraja Cholan in 1006. With the death of Rajaraja Cholan I in 1014 CE and the ascension of Rajendra to the Chola throne in the same year. After a lapse of two years, in 1016, Rajendra sent a naval force to Sri Lanka and brought the Anuradhapura Kingdom under his control.^[11]

Following an expedition to eastern Kerala in 1017, Rajendra captured Kudamalai Nadu.^[17]

In 1018, Rajendra's forces captured the Maldives and Lakshadweep islands, and the same year captured Sandimaaththivu, the Kavaratti island west of Kerala.^[18][18]

In 1019, Rajendra sent another expedition against the Irrataipaadi Elaraiillakam, northern Karnataka and southern Maharashtra. With its new capital at Kalyani in northernmost Karnataka, which the Cholas lost again but recaptured after a battle at Musangi in eastern Karnataka. After a two-year lapse, Rajendra, with his capture of many regions of the Indian mainland, became more ambitious in conquering the northern and north-western parts of India.

He commenced his war expedition in this direction in 1021, capturing Sakkarakkoattam in the south of Chhattisgarh. Then, he sent part of his forces to the Ganges river in the north and the other in a north-westerly direction. At the same time, he stationed himself at Sakkarakkoattam until the two expeditions were complete.

The second expedition went to Uttarapatha and Gangetic region countries towards the Ganges river in the north from Sakkarakkoattam; they captured the regions of Odda Vishayam and Thandabuththi in Odisha, Kosala Naadu in northern Chhattisgarh, Thakkana Laadam and Uttara Laadam in Jharkhand, and Vangala Desam in modern-day Bangladesh, and reached the Ganges.

The Chola Indian Mainland expedition ended in 1022, and details of the countries conquered by his forces in the expedition were included in his Meikeerthi's from 1023. With the return of Rajendra Chola's forces to the Chola capital in 1022, the Royal Guru of Rajendra, Isaana Pandithar, built Gangaikonda Cholaeswarer temple at Kulampandel, Tamil Nadu. With his return, Rajendra claimed a new title, "Gangaikondaan", and gave the title "Gangaikonda Cholan" (the Chola who captured Gangai) to his younger brother, who led the Gangetic expedition. Rajendra commenced the construction of a new city named "Gangaikonda Cholapuram", with a new Siva temple named "Gangaikonda Cholaeswarem" and a large temple water tank called "Chola Gangam", where the holy water brought from the Ganges river was mixed. The Essalam Copper Plates of Rajendra state with the conquest of the Gangetic region, Rajendra constructed the new city of the Gangaikonda Cholapuram, the great Gangaikonda Choleswarer temple, and the sacred Cholagangam Tank at the Udaiyar Palaiyam region of Ariyalur district. In the temple "Gangaikonda Cholaeswarem" he built, the presiding deity of the Karuvarai (Sanctum Sanctorum) called the "Gangaikonda Cholaeswarer" also known as "Peruvudaiyar" – the God Siva in the form of Lingam, the biggest Lingam among the Siva Temples in the world over, having a height of 13 feet (4.0 m) and a circumference of 20 ft (6.1 m). The praśasti mentions Rajendra's conquests:^[19]

On the third Regnal year of Rajendra Chola – the conqueror of the East country, Ganges and Kadaram; this stone inscription was made to record the tax exemption grant given by Rajendra, the one who surrendered to Shiva.^[19]

The Vijayamkonda Cholaeswarem Siva temple of Erumbur in Cuddalore district – the present-day Kadambavanesvara temple near Erumbur – was built to commemorate the victory of Rajendra's forces over Sri Vijaya and many regions of Sumatra. The Kadaremkonda Cholaeswarem Siva temple in Kudimallur in Vellore district – present-day Bhimeswara temple near Kalavai – was built to commemorate Rajendra's victory over Kadarem and many regions of present-day Malaysia.^[20]

Rajendra I's overseas war expedition commenced in 1023; a large fleet of ships with Chola warriors was sent to Sri Vijaya, Palembang in southern Sumatra, which was captured. After that, the fleet captured the adjacent settlement Malaiyur.^[21] From there, the fleet sailed to the nearby island Bangha and captured Mevilibangham. The fleet then sailed to Pannai, on the eastern Sumatran mainland, followed by Ilamuridesam in northern Sumatra. The forces next sailed to Malaysia and captured Vallaipandur in modern-day north-east Malaysia and Kadarem in north-west Malaysia. From here, Rajendra's forces sailed north and captured the adjacent settlement Ilankasokam in south-east Thailand, followed by Mathamalingam, eastern Thailand and Thalaitakkolam in south-west Thailand. From here, the fleet departed to India, en route capturing Manakkavaarem in the Andaman and Nicobar Islands, the southern Myanmar (Burma) seaport city Magpapaalam, and returned to Chola country.^[11] The Chola south-east Asian expedition ended in 1024, and details of the lands conquered by his forces in this expedition were included in his Meikeerthan early silver kasu of 1025.^[22] With Rajendra's victory over Sri Vijaya(m) of Sumatra in 1023, he built a Siva Temple at Erumbur, Tamil Nadu, and named it Vijayamkonda Cholaeswarem.

With his triumph over the Kadaram, Rajendra assumed the new title "Kadaremkondaan", and one of his grandsons who led the Kadaram expedition was given the title "Kadaremkonda Cholan" (the Chola who captured Kadarem). A region of the present-day Kudimallur, Tamil Nadu, was named "Kadarekonda Cholapuram". Some villages in present-day Tamil Nadu still bear the names Kidarankondan in Thiruvaarur and Ariyalur regions (present Gedaramkondan in Ariyalur) and Kadaramkonda Cholapuram (present Narasingpuram). With Rajendra's victories over Kadaram, Malaysia, in 1023, he built a Siva temple in northern Tamil Nadu and named it Kadaremkonda Cholaeswarem.^[23]

Following Rajendra's victories in the wars on the Indian mainland and near-overseas, he built two "magnificent & gigantic temples completely out of Granite stone" as living monuments of his forces' great valour and superior status in this region, which are included in the UNESCO World Heritage Series.^[24] The two granite temples were built to commemorate their triumphs far overseas and as monuments of the Chola's achievements in South-East Asia and the high status of the Medieval Chola Empire in the world history of that period (1025 CE).^[25]

Rajendra led campaigns from 1002 CE; these include the conquest of the Rashtrakutas and the campaigns against the Western Chalukyas. He conquered the Chalukyan territories of Yedatore – a large part of Raichur district between the Krishna and the Tungabhadra rivers – Banavasi in north-western Mysore and the capital Manyakheta. Rajendra erected a Siva temple at Bhatkal. He also conquered Kollipakkai, located north of Hyderabad in present-day Telangana. An excerpt from an inscription in Tamil from Kolar states:

In the eighth year of the reign of Kopparakesarivanmar sri Rajendra Sola Deva, who, while the goddess of Fortune, having become constant, increased, and while the goddess of the great Earth, the goddess of victory in battle and the matchless goddess of Fame, having become his great queens, rejoiced-that in his extended lifetime, conquered with his great war-like army Idaiturai-nadu, Vanavasi shut in by a fence of continuous forests; Kollipakkai, whose walls were surrounded by sulli trees; Mannaikkadakkam whose fortification was unapproachable.^[26]

In 1018 and 1019 CE, Rajendra invaded and conquered the Pandya and Chera Perumal kingdoms.^[27] He appointed one of his sons as viceroy with the title Jatavarman Sundara Chola-Pandya with Madurai as the headquarters in charge of both Pandya and Chera/Kerala.

Rajendra Chola I fought several battles with Western Chalukyas. From 992 CE to 1008 CE, during the reign of Rajaraja I, Rajendra raided and annexed several towns, such as Rattepadi, Banavasi and Toanur.^{[citation needed]}

In 1015, Jayasimha II became the king of Western Chalukyas. He tried to recover the losses suffered by his predecessor Satyashraya, who fled his capital and was later restored to the throne by Raja Raja I as a tribute-paying subordinate. Initially, Jayasimha II was successful because Rajendra was busy with his campaigns in Sri Lanka.^[29] In 1021, after the demise of the Eastern Chalukyan king Vimaladitya of Vengi, Jayasimha supported Vijayaditya VII's claim to the throne against the claims of Rajaraja Narendra, the son of Vimaladitya and Chola princess Kundavai.^[29] Rajendra helped his nephew Rajaraja defeat Vijayaditya.^[30]

Rajendra fought Jayasimha in the Battle of Maski.^[29] Rajendra led a 900,000-strong army and defeated Jayasimha II at the Battle of Maski in 1019 and 1020. On the eastern front, Rajendra led Rajaraja Chola I's army in Vengi and routed the rulers in battle. Vengi was later the site of the coronation of Rajendra's nephew following his victories in the Chola expedition to North India.^{[citation needed]}

Under his father Rajaraja I, Rajendra Chola I's commander Vallavaraiyan Vandiyadevan commanded an army that invaded Sri Lanka and sacked the capital city Anuradhapura.^[31] The new Chola capital was at Polonnaruwa, which was renamed "Jananathamangalam", a title of Rajaraja. Chola official Tali Kumaran erected a Siva temple called Rajarajeshvara ("Lord of Rajaraja") in the town Mahatittha – modern Mantota, Mannar – which was renamed Rajaraja-pura.^[32] Chola-occupied territories on the island were named Mummudicholamandalam after Mummudi Chola or Rajaraja I, Rajendra's father.^[33]

During his reign, Rajendra's father Rajaraja I annexed the Kingdom of Anuradhapura in northern Sri Lanka. Rajendra invaded the Kingdom of Polonnaruwa in the south in 1017.^[34] Chola raids were launched southwards from Rajarata into Rohana. By his fifth year, Rajendra claimed to have completely conquered the island. The whole of Anuradhapura, including the south-eastern province Rohana, was incorporated into the Chola Empire.^[35] According to the Sinhalese chronicle Mahavamsa, the conquest of Anuradhapura was completed in the 36th year of the reign of the Sinhalese monarch Mahinda V – about 1017 to 1018.^[35] But the Cholas never consolidated their control over the south of the island, which lacked large, prosperous settlements to tempt long-term Chola occupation. Under Rajendra, the Chola's predatory expansion in Sri Lanka approached a point of diminishing returns.^[36] According to the Culavamsa and Karandai plates, Rajendra led a large army into Anuradhapura and captured Mahinda's crown, queen and daughter, a vast amount of wealth and the king himself, whom Rajendra took to India as a prisoner to India, where he died in exile in 1029.^[37][35]

11–12 years after the Chola conquest of Rohana, Prince Kassapa, son of Mahinda, hid in Rohana, where Chola forces unsuccessfully searched for him. Soon after the death of Mahinda, Kassapa assumed the Sinhalese monarchy as Kassapa VI – also known as Vikramabahu – and reigned in Rohana from 1029 to 1040 while attempting to organise a campaign of liberation and unification. He became the king of Rohana after the 11–12 years of Chola rule in Rohana. Taking advantage of uprisings in the Pandya and Chera kingdoms,which seems to have no effect in this conflict, 2 Sinhala dandanayakas by the names of Budha and Kiththi massacred the Chola garrisons (on behalf of Kassapa IV) in a 6 month long battle at Palatupana in Rohana. Leftover soldiers of the 95,000-strong Chola army escaped to Pulatthinagara across dhakkina principality. Prince Kassapa IV launched an unsuccessful raid into Pulattinagara but died because of a disease before he could consolidate his power to a second raid into Pulattinagara. A series of non-sinhalese ephemeral aspirants to the throne subsequently appeared and disappeared in Rohana without dislodging the Cholas from the north.^[37] Kassapa VI's mysterious death in 1040, however, brought an end to the war until the rise of Vijayabahu. His successor Mahalana-Kitti (1040–1042) tried to lead an revolt against the Cholas but failed.

Vijayabahu I of Polonnaruwa I (1055–1110) descended from or claimed to be descended from the Sinhalese royal house, the House of Lambakanna II. By the age of seventeen, he had defeated his most-potent rivals in Rohana and was anxious to take on the Cholas.^[37] The crisis in the country left a few scattered, turbulent chiefs and intractable rebels whose allegiance, if any, was at best opportunistic, which proved a problem to both sides in the conflict, frustrating both the Sinhalese kings and the Cholas. Vijayabahu, from his base in Rohana, faced a similar difficulty; he had to contend with the hostility of local chiefs who regarded him as a more-significant threat than the Cholas to their independence. For that reason, the Cholas recruited nominal support from rebel chiefs in Rohana. Vijayabahu needed help consolidating a firm territorial base from which to launch a decisive campaign against the Cholas. On another front, the Cholas needed to eliminate similar opposition in the north. Gradually the wider conflict developed into a prolonged, back-and-forth struggle of raids and counter-raids; the forces of Vijayabahu advanced upon Polonnaruva, and then fell back to fortresses in Dakkhinadesa and Rohana to withstand retaliatory Chola attacks and sieges.^[37] Vijayabahu eventually defeated the Cholas and drove them out of the island restoring ancient Sri Lanka's sovereignty.

In 1019 CE, Rajendra's forces marched through Kalinga towards the Ganges river. In Kalinga, the Chola forces defeated Indraratha, ruler of the Somavamsi dynasty.^[38] Rajendra accepted the help of the Paramaras and the Kalachuris, with whom Indraratha had a bitter enmity, and Rajendra took advantage of this situation. The combined armies defeated Indraprastha, who was probably killed. The Chola army eventually reached the Pala kingdom of Bengal, where they defeated Mahipala. The Chola army also defeated the last ruler of the Kamboja Pala dynasty, Dharmapala of Dandabhukti.^[39][40] The Chola army went on to raid eastern Bengal – modern-day Bangladesh – defeated Govindachandra of the Chandra dynasty, and invaded the Bastar region.^[41][42]

The Tamil praśasti of Rajendra I reads:

(He seized) Śakkarakkōţţam, whose warriors were brave; Madura-maṇḍalam destroyed in a trice, the prosperous city of Nāmaṇaik-kōṇam with its dense groves. Pañcap-paḷḷi whose warriors (bore) cruel bows, Māśunideśa with its green fields; a large heap of family-treasures with many (other) treasures (which he carried away), after having conquered Indraratha of the ancient race of the moon, together with (his) family, in a fight which took place at Ādinagar, (a city) whose fame knew no decline; Oḍḍa-viṣaya which was difficult of approach on account of its dense forest defence; the good Kōśalai-nāḍu where Brahmins assembled; Taṇḍabutti in whose gardens bees abounded, (land which he acquired) after having destroyed Dharmapāla (in) a hot battle; Takkaṇalāḍam, whose fame reached (all) directions, (and which he occupied) after having forcibly attacked Raṇaśura; Vangāḷa-deśā, where the rain water never stopped, (and from which) Gōvindacandra fled, having descended (from his) male elephant; elephants of rare strength, women and treasure, (which he seized) after having been pleased to put to flight in a hot battlefield the strong Mahipāla by the sound of a conch from the deep sea; Uttiralāḍam (on the shore of) the expansive ocean (producing) pearls; and the Gangā whose waters bearing flagrant flowers dashed against the bathing places (tirtha)^[43]

To celebrate his victory in the Ganges, Rajendra constructed a new capital at Gangaikondacholapuram and built Gangaikonda Choleeswarar Temple, which is similar to the Brihadeeswarar Temple at Thanjavur. There has been general disagreement among historians on the nature of the expedition. Early scholars such as V. Venkayya interpreted Rajendra's campaign to "bring the waters of the Ganges into Chola territory" as a pilgrimage to the Ganges river.^[44] This theory has been refuted by later historians, the most notable being K. A. Nilakanta Sastri.^[23] The military nature of the campaign is suggested by the last line of the Thiruvalangadu plates, which state the king erected the Cholaganga tank as a Ganga-jalamayam jayasthambham ("liquid pillar of victory).^[23]

The Chola expedition to the Ganges had a long-lasting influence. According to R. D. Banerji, a Kannadiga chief who accompanied Araiyan Rajarajan on his campaign settled in Bengal and founded the Sena Dynasty.^[23] It is believed the Karnata people of Mithila might have descended from soldiers of the Chola army.^[23] According to the Siddhantasaravali of Trilocana Sivacharya, many Shaivite Brahmins from Bengal were taken to Chola country, where Rajendra granted them lands. They eventually settled in Kanchipuram and the Cauvery Delta, forming the Sivacharya community.^[23]

Srivijaya was a kingdom centred in Palembang, Sumatra, and was ruled by the Sailendra dynasty. During the reign of Mara Vijayatungavarman, Srivijaya had cordial relations with the Chola Empire during the reign of Rajaraja Chola I, leading to Mara Vijayatungavarman building the Chudamani Vihara in Nagapattinam. Sangrama Vijayatunggavarman succeeded Mara.

Khmer Emperor Suryavarman I started a war against the kingdom of Tambralinga on the Malay Peninsula, and requested aid from Rajendra.^[45][46] After learning of Suryavarman's alliance with Rajendra, Tambralinga requested aid from Srivijaya, which Sangrama granted.^[45][47] This led to the Chola invasion of the Srivijiya Empire. This belligerence were partly influenced by religion; the Chola and Khmer Empire were Hindu Shaivites, while Tambralinga and Srivijaya Empires were Mahayana Buddhists.^[48][22]

The Cholas are known to have benefitted from both piracy and foreign trade. Sometimes, Chola naval expeditions led to plunder and conquest as far as South-east Asia.^[49] While Srivijaya controlled two major naval choke points the Malacca and Sunda Straits, the Malacca Strait's north-west opening was controlled from Kedah on the Malay Peninsula side and from Pannai on the Sumatran side.

In 1025 CE, Rajendra's Chola forces crossed the Indian Ocean and invaded Srivijaya, attacking several places in modern-day Malaysia and Indonesia.^[50] The Cholas sacked the capital Kadaram and Pannai on Sumatra, and Malaiyur on the Malay Peninsula. Rajendra also invaded Tambralinga and the Gangga Nagara Kingdom in modern-day Malaysia and southern Thailand.^[51][52][53] Chola forces captured the last ruler of the Sailendra Dynasty Sangrama Vijayatunggavarman.^[21] The Chola invasion was the end of Srivijaya.^[54][55] Srivijaya's maritime power declined under the Chola attack.^[56] Chola forces conquered large portions of Srivijaya, including its ports Ligor, Kedah and Tumasik (now Singapore).^[56][57] The Chola invasion furthered the expansion of Tamil merchant associations such as the Manigramam, Ayyavole and Ainnurruvar into South-East Asia,^{[58][59][60][61]} and for the next century, Tamil trading companies from southern India dominated the region.^[54][55] Rajendra's expedition is mentioned in corrupted form as Raja Chulan in the medieval Malay chronicle Sejarah Melaya, and Malay princes have names ending with Cholan or Chulan, such as Raja Chulan of Perak.^{[62][63][64][65][66]} One record of Rajendra describes him as the King of Lamuri in north Sumatra.^[67] The Chola invasion led to the fall of the Sailendra Dynasty of Srivijaya also coincided with the return voyage of the Buddhist scholar Atiśa from Sumatra to India in 1025.^[68]

Despite the devastation, the Srivijaya mandala survived because the Chola attack was short and only meant to plunder so the invasion failed to install direct administration over Srivijaya. This invasion severely weakened the Srivijayan hegemony, and enabled the formation of regional kingdoms like Kahuripan and its successor Kediri, in Java, which were based on agriculture rather than coastal and long-distance trade. Sri Deva was enthroned as the new king and trading activities resumed. Deva sent an embassy to the court of China in 1028.^[69] The invasion was not followed by direct Cholan occupation, and the region was unchanged geo-politically, trade had considerable consequences. Tamil traders encroached on the Srivijayan realm that was traditionally controlled by Malay traders, and the Tamil guilds' influence increased on the Malay Peninsula and the north coast of Sumatra.^[69]

With the growing presence of Tamil guilds in the region, relations between Srivijaya and the Cholas improved. Chola nobles were accepted in the Srivijaya court, and in 1067, a Chola prince named Divakara or Devakala was sent as a Srivijayan ambassador to the Imperial Court of China. The prince, who was the nephew of Rajendra Chola, was enthroned in 1070 as Kulothunga Chola I. During the Kedah rebellion, Srivijaya asked the Cholas for help. In 1068, Virarajendra Chola launched a naval raid to help Srivijaya reclaim Kedah.^[70] Virarajendra reinstated the Kedah king at the request of the Srivijayan Maharaja, and Kedah accepted Srivijayan sovereignty.^[71][70]

Rajendra I died in 1044 in Brahmadesam, present-day Tiruvannamalai district, Tamil Nadu. Rajendra's son Rajadhiraja I recorded this information in an inscription, which states Rajendra's queen Viramahadevi committed sati upon her husband's death. Her remains were interred in the same tomb at Brahmadesam. It adds the queen's brother Madhuranthaka Parakesari Velan,^[72] who was a general in Rajendra's army, constructed a watershed at the same place in memory of his sister.^[3][73]

According to the Siddanta Saravali of Trilochana Sivacharya, Rajendra Chola I was a poet who composed hymns to praise the god Siva. A commentary on the same work says Rajendra brought several Saivas from the banks of the Ganges river and settled them in Kanchi and across the Chola Empire.^[74]

After his successful campaign for the Ganges river in North India, Rajendra gained the title Gangaikonda Chola (The Chola who took the Ganges river). After his successful South-East Asian campaign, he gained the title "Kadaram Kondan" (He who took Kedah).^[75]

He inherited the title Mummudi Cholan (Chola with three crowns) from his father Mummudi, a title used by Tamil kings who ruled the three kingdoms of Cholas, Pandyas and Cheras.^[76] Rajendra assumed other titles to commemorate his conquests, such as Mudigonda Cholan and Irattapadikonda Cholan.

Rajendra I bore the title Chalukya-Chudamani (Crest Jewel of the Chalukyas).^[77]

Rajendra I had many queens; Tribhuvana or Vanavan Mahadevi, Mukkokilan, Panchavan Mahadevi, Puteri Onangki and Viramahadevi, the last of whom committed sati upon Rajendra's death.^[10] He had seven sons; Rajarajan, Rajadhiraja, Manukula Kesari, Sanga Varman, Rajendra II, Rajamahendran and Virarajendra. Rajarajan was the eldest of the seven but died before reaching thirteen. Manukula Kesari died in 1021 during the war with the Western Chalukyas. Arulmoli Nangaiyar Piranar and Ammangadevi (queen of eastern Chalukya Rajaraja Narendra and the mother of Kulottunga I) are the known daughters of Rajendra.^[10]

Rajendra Chola I built several sites.^[78] Rajendra built Gangaikondacholapuram to commemorate his victory over the Pala Dynasty. The name of the city Gangaikonda Cholapuram means "The City of the Conqueror of Ganga River" or "the town of the one who defeated the kings near the Ganga". The city has an artificial lake, which is filled with water from the Kollidam and Vellar rivers. The outer fortification in the city is wider than the inner one. The remains of the outer fortification consists of a mound encircling the palace.

Rajendra established Gangaikonda Cholapuram as his capital from the mediaeval Chola capital Thanjavur, which became the capital for the next 250 years.^[25] Rajendra I built several temples using plans and infrastructure recommended in Tamil Vastu and Agama sastra texts.^[79] These included a Dharma Sasta, Vishnu and other temples. These temples were destroyed in the late 13th and 14th centuries, except the Brihadishvara temple. The other Chola landmarks are evidenced by soil-covered mounds and excavated, broken pillar stumps and brick walls found over several kilometres from the surviving temple.^[79][80]

Rajendra states Dehejia must have involved the same artisans used by his father and transferred them from Thanjavur.^[81] Most or all of the Chola kings from Rajendra I had their coronations at Gangaikonda Cholapuram. Archaeological excavations have revealed fort walls and palace remains a few kilometres from this temple.

Rajendra also built a royal palace of burnt brick. The ceilings were covered with small, flat tiles laid in several courses in a fine lime mortar. The pillars were probably made of polished wood and were supported on granite bases; a few pillar bases have survived. Iron nails and clamps have been recovered from this palace site. A tunnel links the palace and the temple's inner first prakaara to the north.

Rajendra also developed Koneswaram temple in Trincomalee. The temple to Bhadrakali, which is located further along the complex inland along Konesar Road, benefitted from Rajendra.^[82] The Kali temple is mentioned in the book Birds of Prey (1997) by Wilbur Smith, which is set in the 1660s. The Thirukonasala Mahatyam, describing the origins of the world, Lanka and Koneswaram based on puranic legends, is lost. The historical literature Mattakallappu Manmiyam (Batticaloa Manmiyam) chronicles the Tamil settlement in Batticaloa; it follows the Dakshina Kailasa Puranam and Dakshina Kailasa Manmiam in its description of Koneswaram as one of the nine most-important and sacred sites in the world for Hindus.^[83]

Rajendra also expanded the Pathirakali Amman Temple in Trincomalee. It attracted many pilgrims during his reign.

Rajendra developed an efficient water management system from the village level upwards. The increase in royal patronage, and the number of devadana and bramadeya lands increased the role of the temples and village assemblies. Committees like (tank committee) and totta-variam (garden committees) were active, and the temples had vast resources in land, men and money.

Rajendra built a large tank named Cholagangam in his capital city Gangaikonda Cholapuram, and it was described as the liquid pillar of victory.

Ottakoothar's Vikrama Cholan Ula mentions Rajendra's conquests:

The king Rajendra Chola, generous as Karpaga tree that gives whatever one wants, went with his army, conquered and ruled and protected the land, where Ganges flows and Kadaram. He belongs to the lineage of Vikrama ^[84]

— Ottakoothar, Vikrama Cholan Ula, verse 18

The Malay-language Hikayat Iskandar Zulkarnain was written about Alexander the Great as Dhul-Qarnayn, and from it, the ancestry of several South-East Asian royal families is traced to Iskandar Zulkarnain (Alexander the Great).^[85] through Rajendra (Raja Chulan, Raja Cholan) in the Malay Annals such as the Sumatran Minangkabau royalty.^[86][87]

Several inscriptions of Rajendra commemorating his reign and conquests have been found. An inscription at Adhipuriswara temple in Chengalpattu district gives his natal star as Tiruvadarai. Donations were made to the temple to celebrate the king's birthday in Maargali.^[88] An inscription at Umamahesvara temple in Konerirajapuram, Thanjavur district, refers to donations by Alvar Parantakan Kundavai-Pirattiyar during the third year of Rajendra's reign.^[89]

The walls of Rajarajeswaramudaiya Mahadevar Temple, built by his father and later developed by Rajendra, include inscriptions describing many donations to the temple made by Rajendra.^[90]

Rajendra appointed his son Rajadhiraja as heir apparent to the Chola throne in 1018.^[16] Large military expeditions, like the Pandya and Chalukya wars, were carried out by Rajadhiraja.^[91] The prominent officials of the time were:
