The 1961 Indian annexation of Goa, was an action by India’s armed forces that ended Portuguese rule in its Indian enclaves in 1961. The armed action, code named Operation Vijay by the Indian government, involved air, sea and land strikes for over 36 hours, and was a decisive victory for India, ending 451 years of Portuguese colonial rule in Goa. One of the problems vexing the Indian prime minister Jawarhalal Nehru in the 1950s was what to do about Goa. The situation began to come to a head in 1955 when a group of Goanese and Indian protesters staged a ‘liberation march’ in Goa and more than 20 of them were shot and killed.
