The name Mumbai has been derived from the name of the local Goddess called Mumbadevi. Mumbai has a rich past and cultural heritage. Originally it was a group of seven islands, and was a part of the Maurya Empire during the reign of Ashoka. Later it came under the control of many dynasties till the Silharas wrested the region in early 800s. In 1343 AD, the region was captured by the Kingdom of Gujarat in whose possession it remained for the next 200 years. In 1543, the isles came under the control of the Portuguese and in 1661 ceded as dowry to Catherine de Braganza upon her marriage to Charles II of England. Charles II in turn leased the Island to the British East India Company who named it Bombay. Mumbai city is the capital of Maharashtra. Previously known as Bombay, it one of the world's largest and most densely populated areas. Situated on the west coast of India, this city is known for its deep natural harbour.
