History of Goa:

• After India's independence in 1947, Portugal refused to give up its territories in India.

On 19 December 1961, the Indian Armed Forces liberated Goa, Daman and Diu in "Operation Vijay". The Portuguese Governor-General, Manuel António Vassalo e Silva, surrendered. 19 December is celebrated as "Goa Liberation Day".

The 12th Constitutional Amendment Act, 1962 made Goa, Daman and Diu a Union Territory.
