The development of townships and a significant growth in population came as the city was proclaimed the capital of Bengal under Mughal rule in 1608. During Mughal rule the areas currently under Dhaka district was famous for its textile products – especially the Muslin. Mughal subahdar Islam Khan was the first administrator of the city. Khan named the town "Jahangir Nagar" ("City of Jahangir") in honour of the Mughal emperor Jahangir, although this name was dropped soon after Jahangir's death. The main expansion of the city took place under Mughal general Shaista Khan. The city then measured 19 by 13 kilometres (12 by 8 mi), with a population of nearly a million people. The city passed to the control of the British East India Company in 1757 after the Battle of Plassey and eventually to the Crown, British Empire, in 1765 at the Battle of Buxar. The city's population shrank dramatically during this period as the prominence of Kolkata rose, but substantive development and modernisation eventually followed. A modern civic water supply system was introduced in 1874 and electricity supply launched in 1878. The Dhaka Cantonment was established near the city, serving as a base for British and Indian soldiers.
