Overview

The Indian 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.

Significance

The Indian annexation of Goa in December 1961 brought an end to Portuguese territorial presence in the Indian subcontinent, eliminating what Indian leadership regarded as the last vestige of European colonialism on Indian soil. With a force of approximately 45,000 troops against a Portuguese garrison of 3,500, India conducted a swift military operation that resulted in the capitulation of Portuguese forces under M. A. Vassalo e Silva. Jawaharlal Nehru had initially pursued a political resolution, expecting popular pressure and international opinion to compel Portugal to relinquish its Estado da India territories, but António Salazar's government refused to yield. The decision to use force, advanced by Krishna Menon, marked a significant shift in Indian foreign policy—a non-aligned state resorting to armed annexation despite earlier reliance on diplomatic and moral pressure. The operation folded Goa, Daman, and Diu into the Indian Union and effectively closed the Portuguese Colonial War's Indian theater, though Portugal did not formally recognize the annexation. The event was received domestically as liberation and internationally with division, illustrating the tension between anti-colonial arguments and established norms of territorial sovereignty.
