History
Chattogram has been a port for well over a thousand years, visited by Arab traders and fought over by Bengal and the Arakanese kingdom to the south. The Portuguese knew it as Porto Grande in the 16th century, and Portuguese and Arakanese raiders worked the coast until the Mughal governor Shaista Khan took the city in 1666. The port passed to the East India Company in the later 18th century. In 1930 the revolutionary Surya Sen led a raid on the British armoury here, and in the Second World War the city was a base for the Burma front; Commonwealth war cemeteries at Chattogram and Cumilla hold the dead. Further back, the Mainamati ruins near Cumilla mark Buddhist monasteries of the 8th to 12th centuries.
Sylhet's turning point came in 1303, when its conquest by Muslim forces was followed by the arrival of the Sufi saint Shah Jalal, whose shrine remains the region's spiritual centre. Commercial tea planting began in 1857. In 1947 a referendum placed most of Sylhet in East Pakistan.
The Hill Tracts followed a separate course, governed under special rules as a hill district. The Kaptai dam of the early 1960s flooded the valley around Rangamati and displaced about 100,000 people, most of them Chakma. After 1971 settlement by Bengalis and demands for autonomy led to an insurgency by the Shanti Bahini that ended with a peace accord in 1997. In March 1971 Chattogram was the site of the declaration of independence, and since 2017 Cox's Bazar district has sheltered the Rohingya fleeing Myanmar.
