Goa observed Goa Day on May 30 as its 27^th Statehood anniversary. It was on this day in 1987 when Goa became 25^th State of the Indian Union.
Story of Goa joining Union of India
Goa remained a territory under Portuguese Empire from 1510 to 1947. After Independence India requested Portuguese to cede Goa and few other holdings to India, which was refused by Portugal.
On the contrary, Portugal lodged a complaint against India in the International Court of Justice at The Hague. In 1960, the court held in its judgment that Portugal had right to the enclaves but that India equally had a right to deny Portugal access to the enclaves over Indian Territory.
In December 1961, Indian forces launched Operation Vijay and entered Goa as a result of which the Portuguese forces surrendered. Following this action, a resolution condemning the action of India was proposed in the United Nations Security Council which was vetoed by the USSR. Then, under Indian control, Goa voted in a referendum to become an autonomous, federally administered territory. Goa was attained statehood on May 30, 1987.
Note: Goa Day is different from Goa’s “Liberation Day” that is observed on December 19 every year.
