Unarmed Indians move against Goa border (newsreel)
When India became independent in 1947, Goa remained under Portuguese control. The Indian government of Jawaharlal Nehru insisted that Goa, along with a few other minor Portuguese holdings, be turned over to India. Portugal, however, refused. France, which also had small enclaves in India (most notably Pondicherry, see French India), gave them up. Portugal, however, amended its constitution so that Goa became a Portuguese province and refused to surrender it.
In 1954, unarmed Indians[4] took over the tiny land-locked enclaves of Dadra and Nagar-Haveli. This incident led the Portuguese to lodge a complaint against India in the International Court of Justice at The Hague. The final judgement on this case, given in 1960, held that the Portuguese had a right to the enclaves, but that India equally had a right to deny Portugal access to the enclaves over Goan territory.
In 1955 a group of unarmed civilians, satyagrahis[5] demonstrated against Portugal. At least 22 of them were killed by Portuguese gunfire.[6]
Later the same year, the satyagrahis took over a fort at Tiracol and hoisted the Indian flag. They were driven away by the Portuguese, with a number of casualties. On 1 September 1955, the Indian consulate in Goa was closed. In 1955 also Jawaharlal Nehru declared his government would not tolerate Portuguese presence in Goa. India then instituted a blockade against Goa, Damão and Diu, in an effort to force the Portuguese to leave.
On December 19, 1961, Indian troops crossed the border into Goa. Code named 'Operation Vijay', the move involved sustained land, sea, and air strikes for more than 36 hours; it resulted in the unconditional surrender of Portuguese forces. A United Nations resolution condemning the invasion was proposed by the United States and the United Kingdom in the United Nations Security Council, but it was vetoed by the USSR.
Under Indian rule, Goan voters went to the polls in a referendum and elected to become an autonomous, federally administered territory. Goa was admitted to Indian statehood in 1987.
After annexation by India, the area was under military rule for five months, but the previous civil service was soon restored and the area became a federally administered territory. Goa celebrates its "Liberation Day" on 19 December every year, which is also a state holiday.
