For over 450 years, the coastal enclaves of Daman (Portuguese: Damão) and Diu on the Arabian Sea coast were part of Portuguese India, along with Goa and Dadra and Nagar Haveli. Goa, Daman and Diu were incorporated into the Republic of India on 19 December 1961, by military conquest. Portugal did not recognise the Indian annexation of these territories until the Carnation Revolution of 1974.
