French India, formally the Établissements français dans l'Inde ("French establishments in India"), was a French colony comprising geographically separate enclaves on the Indian subcontinent. The possessions were originally acquired by the French East India Company beginning in the second half of the 17th century, and were de facto incorporated into the Union of India in 1950 and 1954. The French establishments included Pondichéry, Karikal and Yanaon on the Coromandel Coast, Mahé on the Malabar Coast and Chandernagor in Bengal.
