During the French Revolution in the year 1793 the British “East India Company” took control of the region and returned to the French “East India Company” in 1814. However, when the British “East India Company” gained control of the whole of India in the late 1850s, they allowed the French “East India Company” to retain their settlements at Pondicherry, Mahe, Yanam, Karaikal and Chandronagor.

In 1947, the independence of India gave impetus for the union of France’s Indian possessions with former British India and an agreement between French Government and India Government, in 1948, stipulated that the inhabitants of France’s Indian possessions would choose their political future. On a de facto basis, the bureaucracy had been united with India’s on 1 November 1954 and the de jure union of French India with the Indian Union took place in the year 1963. In the process Chandronagor opted to be merged with the State of West Bengal and Pondicherry along with Karaikal, Mahe and Yanam was constituted as a Union Territory in the Indian Union
