Mumbai (previously known as Bombay until 1996) is a natural harbour on the west coast of India, and is the capital city of Maharashtra state. It is India's largest city, and one of the world's most populous cities. It is the financial capital of India. The city is the second most-populous in the world. It has approximately 14 million people. Along with the neighbouring cities of Navi Mumbai and Thane, it forms the world's 4th largest urban agglomeration. They have around 19.1 million people.
The seven islands that form Bombay were home to fishing colonies. The islands were ruled by successive kingdoms and indigenous empires before Portuguese settlers took it. Then, it went to the British East India Company. During the mid-18th century, Bombay became a major trading town. It became a strong place for the Indian independence movement during the early 20th century. When India became independent in 1947, the city was put into Bombay State. In 1960, following the Samyukta Maharashtra movement, a new state of Maharashtra was created with Bombay as the capital. It was renamed Mumbai in 1996.
