when did goa became part of independent india
History of Goa India made many requisitions to the Salazar regime of Portugal to grant their Indian colonies independence, but when that failed, on 18 December 1961, Indian troops crossed the border into Goa and liberated it. Operation Vijay involved sustained land, sea and air strikes for more than thirty-six hours; it resulted in the unconditional surrender of Portuguese forces on 19 December. A United Nations resolution "condemning" the invasion was proposed by the United States and the United Kingdom in the United Nations Security Council, but would be vetoed by the USSR. The territory of Goa was under military rule for five months. However, the previous civil service was soon restored. Goan voters went to the polls in a referendum and voted to become an autonomous, federally administered territory. Goa was later admitted Indian statehood in 1987.
