Sultan Allaudin Shah bin Banbhina (Sindhi: سلطان علاؤالدين شاهه بن بانٻينو) better known as Jam Juna or Juna I (Sindhi: ڄام جوڻو) was the second Sultan of Sindh. He belonged to the Samma dynasty, reigning first as a Diarch to Sultan Sadruddin Shah Banbhina II bin Unar from 1352 to 1368 and then from 1371 to 1389.

Jam Juna ascended to power following the death of Jam Unar in 1352, sharing rule over Sindh with his nephew, Sadruddin Shah Banbhina II. Insha-i-Mahru mentions that both were joint rulers. Masumi attributes a reign of 13 years to Jam Juna. Amidst this period, Hamir Soomro, having suffered defeat, abandoned Sindh and likely sought refuge under the Delhi Sultanate’s protection.

Banbhina II, in alliance with the Mongols, launched multiple attacks on Gujarat and Punjab, prompting Ain-ul-Mulk Mahru, the Governor of Multan, to seek Firuz Shah Tughlaq’s intervention. In response, Firuz Shah Tughlaq tasked Malik-ul-Umra Rukunuddin Amir Hassan with expelling Banbhina II from both Gujarat and Sindh. However, the plan failed, and Banbhina II decisively ended Soomra rule in Sindh. This ultimately led to Firuz Shah Tughlaq’s invasion of Sindh between 1365–67 AD.

Unlike the aggressive and defiant Banbhina II, Jam Juna, an elderly and weaker figure, sought reconciliation with Delhi. He reportedly conveyed his willingness to submit to the Sultan through Syed Jalaluddin Bukhari of Uch, as suggested by Mahru’s correspondence. A letter from a Delhi Sultanate Amir to a military officer instructed the suppression of the Sindh rebellion, which had been fueled by Mongol support. This letter may have been written before Mahru’s governorship of Multan or during his tenure when he received a copy of the directive.

Jam Juna also wrote to Ain-ul-Mulk Mahru, the Governor of Multan, clarifying his position and condemning the actions of the Imperial forces in Sindh. In his letter, he asserted that:

• He had no involvement in the Mongol raids.
• The Imperial troops from Multan had plundered Sehwan and Sukkur, oppressing the local populace.
• Despite repeated provocations, Sindh’s army had exercised restraint on multiple occasions.
• The Multan government’s actions against Sindh were driven by vested interests rather than justice.
• The Imperial forces had wrongfully enslaved Sindhi Muslims and sold them in the market.
• Sindh possessed a formidable military, and any further incursions by Imperial troops would be met with severe consequences.
• The Subahdar of Gujarat and the Gumashta of Sehwan were unfairly holding the Jams accountable for every administrative failure in their regions.

In response to Jam Juna’s letter, Ain-ul-Mulk, the Governor of Multan, denied all accusations and countered that the Jams of Sindh had broken their submission to Delhi following rumors of Firuz Shah Tughlaq’s death during his second Bengal expedition in 1359 AD. He claimed that this submission had originally been secured through Syed Jalaluddin Bukhari.

Ain-ul-Mulk further accused the Sammas of using Mongol forces against the Delhi Sultanate, attacking Muslim territories in Gujarat and Multan, and usurping lands assigned to the Sultan’s representatives in Sehwan. He alleged that the Jams feigned diplomacy while secretly launching attacks on Sehwan’s administration.

He warned the Jams to remain as submissive as they had been under Bakram Khan, possibly referring to the Sammas of Northern Hyderabad and Nawabshah, who had submitted to Firuz Shah Tughlaq in 1351 AD. Drawing a provocative comparison, he stated that Hindu rulers who sent their daughters to the Royal Harem never rebelled, yet Sindhis, whom he likened to Raja Dahir’s daughters, were treacherous and untrustworthy. He dismissed Sindh’s military strength, remarking that the larger the prey, the greater the hunt.

In 1364 AD, Firuz Shah Tughlaq launched an expedition against Sindh, citing the defiance of the Sammas and their alliance with the Mongols in raids on Gujarat and Punjab.

Jam Juna, seen as more conciliatory, was accused by the Delhi authorities of failing to control Banbhina II’s actions. Despite diplomatic efforts, Sindh’s forces, including those led by Jam Juna, resisted the Imperial advance. Firuz Shah Tughlaq’s army suffered heavy losses due to ambushes near Samanagar and shortages of supplies in the Rann of Cutch, forcing a retreat to Gujarat. The failure of this campaign prompted Firuz Shah Tughlaq to prepare for a second invasion.
