Bengal Subah

The Bengal Subah, also referred to as Mughal Bengal, was the largest subdivision of Mughal India encompassing much of the Bengal region, which includes modern-day Bangladesh, the Indian state of West Bengal, and some parts of the present-day Indian states of Bihar, Jharkhand and Odisha between the 16th and 18th centuries. The state was established following the dissolution of the Bengal Sultanate, a major trading nation in the world, when the region was absorbed into the Mughal Empire. Bengal was the wealthiest region in the Indian subcontinent.

Bengal Subah has been variously described the "Paradise of Nations" and the "Golden Age of Bengal". It alone accounted for 40% of Dutch imports from Asia. The eastern part of Bengal was globally prominent in industries such as textile manufacturing and shipbuilding, and it was a major exporter of silk and cotton textiles, steel, saltpeter, and agricultural and industrial produce in the world. The region was also the basis of the Anglo-Bengal War.

By the 18th century, Bengal emerged as a semi-independent state, under the rule of the Nawabs of Bengal, who acted on Mughal sovereignty. It started to undergo proto-industrialization, making significant contributions to the first Industrial Revolution, especially industrial textile manufacturing. In 1757 and 1764, the Company defeated the Nawab of Bengal at the Battle of Plassey and the Battle of Buxar, and Bengal came under British influence. It was deindustrialized after being conquered by the British East India Company. In 1765, Emperor Shah Alam II granted revenue rights over Bengal to the Company and the judicial rights in 1793. In 1803, the Emperor ceased to be the suzerain of the Company and the "Province of Bengal, Behar and Orissa" of the Mughal Empire was thus formally annexed into the Presidency of Fort William of the East India Company. In 1813, the East India Company Act 1813 transferred sovereignty of the Company's territories to the Crown.
