The Annexation of Goa was the process in which the Republic of India annexed the Portuguese State of India, the then Portuguese Indian territories of Goa, Daman and Diu, starting with the armed action carried out by the Indian Armed Forces in December 1961. In India, this action is referred to as the "Liberation of Goa". In Portugal, it is referred to as the "Invasion of Goa". Jawaharlal Nehru had hoped that the popular movement in Goa and the pressure of world public opinion would force the Portuguese Goan authorities to grant it independence, but without success; consequently, Krishna Menon suggested taking Goa by force.
The operation was codenamed Operation Vijay (meaning "Victory" in Sanskrit) by the Indian Armed Forces. It involved air, sea and land strikes for over 36 hours, and was a decisive victory for India, ending 451 years of rule by Portugal over its remaining exclaves in India. The engagement lasted two days, and twenty-two Indians and thirty Portuguese were killed in the fighting. The brief conflict drew a mixture of worldwide praise and condemnation. In India, the action was seen as a liberation of historically Indian territory, while Portugal viewed it as an aggression against its national soil and citizens. Justifying the successful military action, Nehru remarked that the "Portuguese ultimately left no choice open to us."
