The old names Bombay, Madras and Calcutta were changed for the following reasons
~ To revert back to the local names from anglicized names of British origin
~ To change any misspellings
~ To change from European names to Indian names
Some cities that have changed their names are Bengaluru (formerly Bangalore), Mysuru (formerly Mysore), Thiruvananthapuram (formerly Trivandrum) and Kochi (formerly Cochin)
