Passage: In accordance with the Royal Charter of 27 March 1668, England leased these islands to the English East India Company in 1668 for a sum of £10 per annum. The population quickly rose from 10,000 in 1661, to 60,000 in 1675. The islands were subsequently attacked by Yakut Khan, the Muslim Koli admiral of the Mughal Empire, in October 1672, Rickloffe van Goen, the Governor-General of Dutch India on 20 February 1673, and Siddi admiral Sambal on 10 October 1673.In 1687, the English East India Company transferred its headquarters from Surat to Bombay. The city eventually became the headquarters of the Bombay Presidency. Following the transfer, Bombay was placed at the head of all the company's establishments in India. Towards the end of the 17th century, the islands again suffered incursions from Yakut Khan in 1689–90. The Portuguese presence ended in Bombay when the Marathas under Peshwa Baji Rao I captured Salsette in 1737, and Bassein in 1739.
