Silveira set fire to the western coast leading from Bandora through Thana and Basai to Surat. Portuguese General Nuno da Cunha discovered that the son of Meliqueaz, the governor of Diu, Malik Tokan was fortifying Basai with 14,000 men. Seeing this fortification as a threat, Nano da Cunha assembled a fleet of 150 ships with 4000 men and sailed to north of Basai. Upon seeing the naval superiority of the Portuguese, Malik Tokan attempted to initiate a peace agreement with Nano da Cunha. Upon rejection, Malik Tokan was forced to fight against the Portuguese. Despite bringing fewer soldiers, the Portuguese managed to kill most of the enemy while losing only a few of their own. The Treaty of Bassein was signed by Bahadur Shah of Gujarat and the Kingdom of Portugal on 23 December 1534 while on board the galleon São Mateus. Based on the terms of the agreement, the Portuguese Empire gained control of the village of Basai as well as its territories, islands and seas including Bombay. The village was renamed to Baçaim and became the northern capital of Portuguese territories in India. Garcia de Sá was later appointed as the first Captain (governor) of Baçaim by his brother-in-law Nuno da Cunha in 1536, who ruled until 1548 when the governorship was passed onto Jorge Cabral. The first cornerstone for the Bassein Fort was laid by António Galvão. Under Portuguese rule, the Bassein Fort was the Northern Court, or 'Corte da Norte', functioning as the headquarters of the Court of the North. Baçaim became the capital of the Northern Province, the most productive village of Portuguese India and became a resort for Portuguese 'fidalgos' (noblemen and wealthy merchants). A great Portuguese person would be called 'Fidalgo ou Cavalheiro de Baçaim' (Nobleman of Baçaim). By 1674, the Portuguese constructed 2 colleges, 4 convent schools and 15 churches in total in Baçaim's territories. For approximately 205 years, the presence of the Portuguese made the surrounding area a vibrant and opulent village. The local ethnic community were called 'Norteiro' (Northern men), named after the Court of the North functioning out of the fort. In 1674, about 600 Arab pirates from Muscat entered Baçaim via the west and pillaged the churches in Baçaim. The unexpected attack weakened the Portuguese control outside the fort walls and Maratha warriors stationed in the west isolated them further. Maratha era In the 18th century, Vasai Fort
