Recently, the Indian Navyconducted a Seminar to commemorate the Diamond Jubilee (50 Years) of the liberation of Goa.Goa Liberation Day is celebrated on 19th December every year.
The day marks the occasion when the Indian armed forces freed Goa in 1961 from 450 years of Portuguese rule.
The Portuguese colonized several parts of India in 1510 but by the end of the 19th-century Portuguese colonies in India were limited to Goa, Daman, Diu, Dadra, Nagar Haveli and Anjediva Island (a part of Goa).
As India gained independence on 15th August, 1947, it requested the Portuguese to cede their territories but they refused.
The Goa liberation movement started off with small scale revolts, but reached its peak between 1940 to 1960.
In 1961, after the failure of diplomatic efforts with the Portuguese, the Indian Government launched Operation Vijay and annexed Daman and Diu and Goa with the Indian mainland on 19th December.
On 30th May 1987, the territory was split and Goa was formed. Daman and Diu remained a Union Territory.
