Muslim rule
In 1350 CE, Goa was conquered by the Bahmani Sultanate. However in 1370, the Vijayanagar empire, a resurgent Hindu empire situated at modern day Hampi, reconquered the area. The Vijayanagar rulers held on to Goa for nearly 100 years, during which its harbours were important landing places for Arabian horses on their way to Hampi to strengthen the Vijaynagar cavalry. In 1469, however, Goa was reconquered, by the Bahmani Sultans of Gulbarga. When this dynasty broke up in 1492, Goa became a part of Adil Shah's Bijapur Sultanate, who made Goa Velha their second capital. The present Secretariat building in Panaji is a former Adil Shahi palace, later taken over by the Portuguese Viceroys as their official residence.
Portuguese conquest
In 1498, Vasco da Gama rounded the Cape of Good Hope and landed at Calicut. 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, the Muslim king of Bijapur, Albuquerque returned in force and captured the city, killing the Muslim inhabitants Church in Old Goa.
Albuquerque and his successors left almost untouched the customs and constitutions of the thirty village communities on the island, only abolishing the rite of sati (widow-burning). A register of these customs (Foral de usos e costumes) was published in 1526; it is among the most valuable historical documents pertaining to Goan customs.
Goa was the base for Albuquerque's conquest of Malacca (1511) and Hormuz (1515). Albuquerque intended it to be a colony and a naval base, as distinct from the fortified factories established in certain Indian seaports. Goa was made capital of the Portuguese Vice-Kingdom in Asia, and the other Portuguese possessions in India, Malacca and other bases in Indonesia, East Timor, the Persian Gulf, Macau in China and trade bases in Japan were under the suzerainty of its Viceroy. By mid-16th century, the area under occupation had expanded to most of present-day limits.
Goa was granted the same civic privileges as Lisbon. Its senate or municipal chamber maintained direct communications with the king and paid a special representative to attend to its interests at court. In 1563 the governor even proposed to make Goa the seat of a parliament representing all parts of the Portuguese east but this was rejected by the king.
The Portuguese set up a base in Goa in their quest to control the spice trade. Merchandise from all parts of the East was displayed in its bazaar, and separate streets were set aside for the sale of different classes of goods–Bahrain pearls and coral, Chinese porcelain and silk, Portuguese velvet and piece-goods, drugs and spices from the Malay Archipelago.
In 1542, St. Francis Xavier mentions the architectural splendour of the city; but it reached the climax of its prosperity between 1575 and 1625. Travellers marvelled at Goa Dourada, or Golden Goa, and there was a Portuguese proverb, "He who has seen Goa need not see Lisbon."
