Explanation: Goa, a region on the western coast of India, had a long history of colonial rule under the Portuguese. The Portuguese first arrived in Goa in the 16th century and established their rule over the region. For over 450 years, Goa remained under Portuguese control, making it one of the longest-standing European colonies in Asia.
India, after gaining independence from British rule on August 15, 1947, sought to integrate all territories under its sovereignty. However, Goa, Daman, and Diu remained under Portuguese control. The Indian government attempted to negotiate with Portugal to transfer these territories to India, but these efforts were unsuccessful.
On December 18, 1961, India launched a military operation known as Operation Vijay to liberate Goa from Portuguese control. The operation was swift and successful, and Goa was integrated into the Indian Union. This event marked a significant milestone in India's history, as it completed the process of integrating all territories under Indian sovereignty.
The date of December 18, 1961, is celebrated as Goa Liberation Day in Goa and is a public holiday in the state. It commemorates the end of colonial rule and the integration of Goa into the Indian Union. The liberation of Goa was a crucial event in the post-independence period of India, as it demonstrated the country's resolve to reclaim its territories and assert its sovereignty.
It is important to distinguish between the different dates mentioned in the options. August 15, 1947, marks India's independence from British rule, while January 26, 1950, is the date when India became a republic and adopted its constitution. These dates are significant in the broader context of India's history but are not related to Goa's liberation from Portuguese rule.
Understanding the historical context and the specific events surrounding Goa's liberation is crucial for comprehending the significance of December 18, 1961, in the history of Goa and India. This date represents the end of colonial rule and the beginning of Goa's integration into the Indian Union, marking a new chapter in the region's history.
