Their was a place called GOA in Portugual and India in Britain. but, Britishers and Portuguese thought that these should be placed alongside of China and Pakistan in Asia. So, they pasted these lands on Asian map.

On 12 February 1502, Gama sailed with a fleet of twenty warships, with the object of enforcing Portuguese interests in the east. This was subsequent to the voyage of Pedro Álvares Cabral, who had been sent to India two years earlier. (Swinging far to the west across the Atlantic in order to make use of the pattern of favourable winds, Cabral became the official European discoverer of Brazil.) When he finally reached India, Cabral learned that the Portuguese citizens who had been left by Gama at the trading post had been murdered.
After encountering further resistance from the locals, he bombarded Calicut and then sailed south of Calicut to reach Cochin, a small kingdom where he was given a warm welcome. He returned to Europe with silk and gold.
Once he had reached the northern parts of the Indian Ocean,
Gama waited for a ship to return from Mecca and seized all the merchandise on it. He then ordered that the hundreds of passengers be locked in the hold and the ship - which was named Mîrî, and which contained many wealthy Muslim merchants - to be set on fire.[13] When Gama arrived at Calicut on October 30, 1502 the Zamorin was willing to sign a treaty.[14]
Gama assaulted and exacted tribute from the Arab-controlled port of Kilwa in East Africa, one of those ports involved in frustrating the Portuguese. His ships engaged in privateer actions against Arab merchant ships, and then destroyed a Calicut fleet of twenty-nine ships. Following that battle he extracted favorable trading concessions from the Zamorin, returning to Portugal in September 1503.
In 1510, the Portuguese defeated the ruling Bijapur kings with the help of a local ally, Timayya, leading to the establishment of a permanent settlement in Velha Goa (or Old Goa).
The Portuguese converted a large portion of their subjects in Goa to Christianity. The repeated wars of the Portuguese with the Marathas and the Deccan sultanate, along with the repressive religious policies of Portuguese led to large migrations of Goans to neighbouring areas.
In 1510, Portuguese admiral Afonso de Albuquerque attacked Goa at the behest of the local cheftian Thimayya. After losing the city briefly to its former ruler, Ismail Adil Shah, the Muslim king of Bijapur, Albuquerque returned in force only three months later, on November 25, with a fleet fully renovated. In less than a day they took possession of Goa from and his Ottoman allies, who surrendered on 10 December.
It is estimated that 6000 of the 9000 Muslim defenders of the city died, either on the fierce battle in the streets or drowned while trying to escape.
