The East India Company (EIC) was an English, and later British, joint-stock company founded in 1600 and dissolved in 1874. It was formed to trade in the Indian Ocean region, initially with the East Indies, and later with East Asia. The company gained control of large parts of the Indian subcontinent and colonised parts of Southeast Asia and Hong Kong. At its peak, the company was the largest corporation in the world by various measures and had its own armed forces in the form of the company's three presidency armies, totalling about 260,000 soldiers, twice the size of the British army at the time.

The Battle of Plassey was a decisive victory of the British East India Company, under the leadership of Robert Clive, over the Nawab of Bengal and his French allies on 23 June 1757. Robert Clive was paid £1 million by the Jagat Seth family - a rich Indian family business group - to defeat Siraj-ud-Daulah. The victory was made possible by the defection of Mir Jafar, Nawab Siraj-ud-Daulah's commander in chief who was also paid by the Jagat Seths. The battle helped the British East India Company take control of Bengal in 1772. Over the next hundred years, they continued to expand their control over vast territories in the rest of the Indian subcontinent, including Burma.
