When was the commercial colonization of India commenced?

Company rule in India (sometimes, Company Raj, "raj", lit. "rule" in Hindustani) refers to the rule or dominion of the British East India Company over parts of the Indian subcontinent. This is variously taken to have commenced in 1757, after the Battle of Plassey, when Mir Jafar, the new Nawab of Bengal enthroned by Robert Clive, became a puppet in the Company's hands; in 1765, when the Company was granted the diwani, or the right to collect revenue, in Bengal and Bihar; or in 1773, when the Company established a capital in Calcutta, appointed its first Governor-General, Warren Hastings, and became directly involved in governance.
