European traders first reached Indian shores with the arrival of the Portuguese explorer Vasco da Gama in 1498 at the port of Calicut, in search of the lucrative spice trade. Just over a century later, the Dutch and English established trading outposts on the Indian subcontinent, with the first English trading post set up at Surat in 1613. Over the course of the seventeenth and early eighteenth centuries, the British defeated the Portuguese and Dutch militarily but remained in conflict with the French, who had by then sought to establish themselves in the subcontinent. The decline of the Mughal Empire in the first half of the eighteenth century provided the British with the opportunity to establish a firm foothold in Indian politics. After the Battle of Plassey in 1757, during which the East India Company's Indian Army under Robert Clive defeated Siraj ud-Daulah, the Nawab of Bengal, the Company established itself as a major player in Indian affairs, and soon afterward gained administrative rights over the regions of Bengal, Bihar and Midnapur part of Odisha, following the Battle of Buxar in 1764. After the defeat of Tipu Sultan, most of South India came either under the Company's direct rule, or under its indirect political control as part a princely state in a subsidiary alliance. The Company subsequently seized control of regions ruled by the Maratha Empire, after defeating them in a series of wars. The Punjab was annexed in 1849, after the defeat of the Sikh armies in the First (1845–1846) and Second (1848–49) Anglo-Sikh Wars.
