Bengal Sultanate–Kingdom of Mrauk U War of 1512–1516

The Bengal Sultanate–Kingdom of Mrauk U War of 1512–1516 was a conflict in the 16th century between the Bengal Sultanate and the Kingdom of Mrauk U.

Background
After the Reconquest of Arakan, the Kingdom of Mrauk U was established as a Bengali protectorate. By the 16th century, Mrauk U challenged Bengali hegemony and declared independence several times. Southeastern Bengal, including the port of Chittagong, often fell under Arakanese rule.

Conflict
During Alauddin Husain Shah's expeditions to Tripura, the ruler of Arakan helped Dhanya Manikya, the ruler of Tripura and expelled Husain Shah's officers from Chittagong. In 1513, Husain Shah assigned the charge of Arakan expedition to Paragal Khan. Paragal Khan advanced from his base on the Feni River. The expedition of territory to the western bank of Kaladan river was placed under his governorship administration. The hostilities probably ended in 1516, when Mrauk U recognized Bengali sovereignty over Chittagong and northern Arakan. As a result of the conflict, Mrauk U again became a vassal of the Bengal Sultanate.

Aftermath
After the war, Paragal Khan was appointed the governor of Chittagong region. Paragal Khan with his son, Chhuti Khan, developed a military garrison in Paragalpur. The site was chosen to defend the Bengal Sultanate's borders from pirates from the Kingdom of Mrauk U in the South. It was named Laskarpur (after Laskar soldiers) before being renamed Paragalpur after Paragal Khan. Syed Sultan, noted medieval poet, was from Paragalpur
