The city of Bombay originally consisted of seven islands, namely Colaba, Mazagaon, Old Woman's Island, Wadala, Mahim, Parel, and Matunga-Sion. The history of this group of islands located on the west coast of India goes way back to the stone ages. Stone age implements have been found at several sites in these islands. The coastal regions, and presumably the islands were the home of the Koli fisher folk in the distant past.The British decided to develop these islands into a city and a centre of commerce. They have started factories in many places and many commercial treaties were signed with local rulers. In the four hundred years since then, the city has grown by a series of land reclamations, which now link the original islands into one mass. The British lured skilled workers and traders to move to this British holding. The opportunities for business attracted many Gujarati communities.
