The development of New Imperialism saw the conquest of nearly all eastern hemisphere territories by colonial powers. The commercial colonization of India commenced in 1757, after the Battle of Plassey, when the Nawab of Bengal surrendered his dominions to the British East India Company, in 1765, when the Company was granted the diwani, or the right to collect revenue, in Bengal and Bihar, or in 1772, when the Company established a capital in Calcutta, appointed its first Governor-General, Warren Hastings, and became directly involved in governance.
