In 1687, the Company shifted its main holdings from Surat to Bombay, which had become the administrative centre of all the west coast settlements. Following the transfer, Bombay was placed at the head of all the Company's establishments in India. However, the onset of plague and cholera delayed implementation, and the headquarters was not actually moved to Bombay until 1708. During the Governorships of John Gayer, Nicholas Waite, and William Aislabie (1694–1715), the Bombay Governors also held the title of "General". Their main title, meanwhile, continued to be "President", with Governor of Bombay being a supplementary title and role.
