A law has come into force in India changing the name of the federal territory of Pondicherry - which will now be called Puducherry.
Officials say the move is to reflect the indigenous history of the region.
Puducherry, which means "new village", was the original Tamil name before it was changed by the French.
It was a French colony for more than 200 years, becoming part of the modern Indian state in 1963, 16 years after India's independence.
Several Indian cities have been renamed in recent years to reflect local languages and nationalist sentiment - including Mumbai for Bombay and Chennai for Madras.
