Cuddalore, also spelt as Kadalur^{[note 1]} (/kʌdəˈlɔːr/ ^ⓘ), is a heavy industries hub and a port city, and headquarters of the Cuddalore District in the Indian state of Tamil Nadu. Situated south of Chennai, Cuddalore was an important city and port during the British Raj.

While the early history of Cuddalore remains unclear, the city first rose to prominence during the Pallavas' and Medieval Cholas' reign. After the fall of the Cholas, the town was ruled by various dynasties like Pandyas, Vijayanagar Empire, Madurai Nayaks, Thanjavur Nayaks, Thanjavur Marathas, Tipu Sultan, French and the British Empire. Cuddalore was the scene of the Seven Years' War and the Battle of Cuddalore in 1758 between the French and British. It has been a part of independent India since 1947. During the 2004 Indian Ocean earthquake, and the subsequent tsunamis generated, Cuddalore was one of the affected towns, with 572 casualties.

Apart from fishing and port-related industries, Cuddalore houses chemical, pharmacological and energy industries in SIPCOT, an industrial estate set up by the state government. The city is administered by municipal corporation covering 101.6 km² . It had a population of 308,781 in 2011. Cuddalore is a part of the Cuddalore legislative assembly constituency, a part of the Cuddalore Lok Sabha constituency. There are 25 schools, two arts and science colleges and two engineering colleges in the city. There is one government hospital, six municipal maternity homes, and 42 other private hospitals that take care of the citizens' healthcare needs. Roadways are the primary means of transportation, while the town also has rail connectivity. The nearest airport is Chennai International Airport, located 200 km (120 mi) away from the city, and another local airport is located in the district at Neyveli township is Neyveli Airport. The nearest seaport is Cuddalore Port where it handles small cargo ships, and the construction of port entry is underway. The closest major seaport is Karaikal port, located 100 km (62 mi) away from the town. Cuddalore is famous for educational institutions and medical establishments.

Before the English took control, Cuddalore (anglicised) was called கூடலூர், Kūṭalūr meaning confluence in Tamil.^[1] It is situated on the backwater formed by the confluent estuaries of the rivers viz., Ponnaiyar (South Pennar river flowing through Karnataka and Tamil Nadu), Kedilam, Uppanar and Paravanar. The Cuddalore district historically consisted of Chola Nadu and Nadu Naadu. The name Nadu Naadu meaning middle country may originate from its location between Chola Nadu and Tondaimandalam; or between the Pallavas and the Cholas; or between central territories and the ocean.^[2]

From ancient times the old town has been a seaport. For two centuries, Cuddalore was subject to several foreign powers including the Netherlands, Portugal, France, and the British. Until 1758 Cuddalore was the capital to the South Indian territories which were under British control. Britain ruled a more significant part of South India (entire Tamil Nadu, parts of present Andhra Pradesh, Kerala and Karnataka) from this fort (St. David).

In the early 17th century, the Dutch obtained permission from the ruler of Cuddalore to build a fort there, but political pressure from their Portuguese rivals forced them to abandon it.

Later, the French and English came to Cuddalore for trade and business. The French established a settlement 16 kilometres (10 mi) up the coast at Pondicherry in 1674, followed in 1690 by Fort St. David's British colony at Cuddalore.

During the 18th century, various wars between the European powers spilt over to their colonial empires, and their allies, including those in the Indian subcontinent. During this period the French and British fought several times in the area.

In 1746, during First Carnatic War, part of the Austrian Succession War, French forces besieged the British at Fort St. David for several months before being driven off in 1747.

In 1758, during the Seven Years' War, the French took the fort, and there was an inconclusive naval action, the Battle of Cuddalore, off the coast. The fort was later abandoned, in 1760, when the British attacked Pondicherry.

In 1782, during the Second Anglo-Mysore War, the French again took Cuddalore at the time of the American War of Independence and were besieged there in 1783 by the British. During the siege French and British naval forces again clashed off the Cuddalore coast. The siege failed, but the fort was returned to the British in 1795. There were five different naval actions off the coast during this period, all of which were indecisive.^[3]

Some Cuddalore streets retain their British names, such as Clive Street, Wellington Street, Sloper Street, Canning Street, Rope Street (Rope Street, Wellington Street, Sloper Street and Canning Street jointly known as Salangukara Village), Lawrence Road and Imperial Road. The Cuddalore Central Prison, opened in 1865, is a historically significant landmark. Subramania Bharati and other political leaders served prison terms there.

Tsunami waves that followed the 2004 Indian Ocean earthquake near Sumatra hit India's eastern coast on 26 December 2004 at 8:32 a.m. (IST), resulting in 572 casualties. Several fishing hamlets disappeared, while Silver Beach and the historically significant Cuddalore Port was devastated. Fort St. David survived without damage. On 30 December 2011, Cyclone Thane caused widespread damage to crops and buildings.

Cuddalore is located at  11°45′N 79°45′E / 11.75°N 79.75°E / 11.75; 79.75. It has an average elevation of 6 m (20 ft). The land is completely flat with large black and alluvial soil inland and coarse sand near the seashore. The sandstone deposits in the town are popular. The Pennayar River runs north of the town, while Gadilam River runs across it. Cuddalore is situated at 200 km (120 mi) from the state capital Chennai and 18 km (11 mi) from Puducherry, the neighbouring union territory.^[4]

The Cuddalore Formation of the Cauvery Basin received siliciclastic detritus from inland areas of the Southern Granulite Terrain (SGT). It represented continental–fluvial sedimentation in the eastern continental margin of South India during the Miocene. Indian Summer Monsoon was thought to be initiated in the early Miocene and intensified during the middle Miocene causing major climatic shifts in the Indian subcontinent. In the present work, detailed mineralogical and geochemical studies on the siliciclastic Cuddalore Formation have been carried out to understand the provenance and paleoclimatic conditions during the Miocene. The paleocurrent direction, textural immaturity and framework detrital modes of sandstones suggest rapid uplift of basement and sediment source from nearby Madras Block of SGT. Various diagnostic immobile trace element ratios such as Th/Sc, Co/Th, La/Sc, La/Co suggest a tonalite–trondhjemite–granodiorite–charnockite provenance, and somewhat more felsic composition of source area compared to the present upper continental crust (UCC).^[5]

Being a coastal town, historically, Cuddalore's primary industry was fishing. Although Cuddalore was once a port town, the shipping trade has now moved to larger centres. Cuddalore also hosts the heavy chemical, pharmacological and energy industries in SIPCOT, an industrial estate set up by the state government. The National Thermal Power Corporation (NTPC) and Tamil Nadu Electricity Board (TNEB) planned to commence power plants around the town.^[13]

The industrial development in Cuddalore's recent past has resulted in extreme pollution. SIPCOT, the central industrial area in the town is a "global toxic hotspot."^[20] Local communities have voiced concern about industrialization and pollution.^[21] The SIPCOT chemical industry estate in Cuddalore was investigated in November 2002 by a team from the Indian People's Tribunal headed by J. Kanakaraj. The group reported "a noticeable stench of chemicals in the air". The report published in July 2003 noted that "Villages like Kudikadu, Thaikal, Eachangadu and Sonnanchavadi lie in a virtual 'gas chamber' surrounded on three sides by chemical factories and bounded on the fourth by the river".^[22] There are reports of illegal dumping of toxic waste.^[23] On 22 March 2008, a report for the "Tamil Nadu Pollution Board" prepared by the Nagpur-based "National Environmental Engineering Research Institute" found that residents of the SIPCOT area of Cuddalore were at least 2000 times more likely than their counterparts to contract cancer in their lifetimes due to exposure to high levels of toxic gases from chemical industries in the region.^[24]

The Cuddalore Port operates at the confluence of the Gadilam River and the Paravanar River. The ships anchor in midstream at about 1.5 kilometres (1 mi) from the shore, where cargo is loaded and discharged through lighters. There is a bar at the mouth of the combined river, which maintains a depth of 1.5–1.8 metres (5–6 ft) at low water. During July to September, the depth over the bar is reduced to about 0.91–1.22 m (3–4 ft). Other ports under construction in Cuddalore are Thiruchopuram port, Silambimangalam port, Parangipettai port (Porto Nova) and PY-03 Oil Field (operational).^[25]

Fort St David, situated on the River Gadilam near Devanampattinam and acquired in 1653 CE by Elihu Yale, a Christian slave-trader and cruel slave master, is one of the most visited tourist attraction in Cuddalore. The wealth embezzled and extracted by him was infused into Yale University.^{[citation needed]} Only two decades later, in 1677, when Shivaji captured Gingee, the fort fell into the Marathas' hands. In 1690, the British East India Company purchased the fort and the adjacent villages (within "ye randome shott of a piece of ordnance".) A great gun was fired to different points of the compass. All the country within its range, including the town of Cuddalore, passed into English possession. The villages thus obtained are called "cannonball villages".^[64] The fortifications were strengthened in 1693, 1698, 1702, 1725, 1740 and 1745. In 1746 Fort St. David became the British headquarters for British India. The British ruled a more significant part of south India (Tamil Nadu, parts of the present- Andhra Pradesh, Kerala and Karnataka) from Fort St. David. An attack by Dupleix was successfully repulsed. In 1756, Clive was appointed governor. The French captured the fort in 1758 but in 1760 relinquished it to Sir Eyre Coote of the British East India Company. The French recaptured the fort in 1782 and held it in 1783 during the Battle of Cuddalore. In 1785 the fort passed into British possession. By this time, however, the centre of British rule was Fort St George.^[65][66]
