The current term for the Indian city previously known as Bombay. Mumbai comes from the local Marathi language. The renaming of some Indian cities and states began with the end of Imperial British rule in 1947. A 1956 reorganization of states, changes to local languages and differences between Indian and British English caused more and changes continue. Other Indian cities have also formally switched to the names in their native languages, including Kolkata, formerly Calcutta.
