East India Company, also called English East India Company, formally (1600–1708) Governor and Company of Merchants of London Trading into the East Indies or (1708–1873) United Company of Merchants of England Trading to the East Indies, English company formed for the exploitation of trade with East and Southeast Asia and India, incorporated by royal charter on December 31, 1600. Starting as a monopolistic trading body, the company became involved in politics and acted as an agent of British imperialism in India from the early 18th century to the mid-19th century. In addition, the activities of the company in China in the 19th century served as a catalyst for the expansion of British influence there.

The company was formed to share in the East Indian spice trade. That trade had been a monopoly of Spain and Portugal until the defeat of the Spanish Armada (1588) by England gave the English the chance to break the monopoly. Until 1612 the company conducted separate voyages, separately subscribed. There were temporary joint stocks until 1657, when a permanent joint stock was raised.
