"When Vasco da Gama landed in Calicut on the southwestern Malabar coast of India in 1498, the Vijayanagara empire was about to reach its apex. The Portuguese pursued their pepper trade farther south on the Malabar coast. In the decade after the fall of the empire, they decided as a commercial strategy to hedge their bets and to commence purchasing pepper from the Kanara region. During 1568–1569, they took possession of the coastal towns of Onor (now Honavar), Barcelor (now Basrur), and Mangalore and constructed fortresses and factories at each location.

Onor (Modern Honnavar) was located on the banks of the Sharavathi River, where the river widened into a lake, two miles (3 km) upstream from its mouth. Built strategically on a cliff, the Portuguese fort contained homes for thirty casados (married settlers). A natural sandbank kept out the large ocean-going ships, leaving the harbour accessible only to small craft. Approximately, 35 miles (56 km) farther upstream, the Portuguese maintained a weighing station at Gersoppa, where they purchased the pepper. During the latter part of the 16th century and the first half of the 17th, Onor not only became the principal port for the export of Kanara pepper, but also the most important Portuguese supply point for pepper in all of Asia.

Located some 50 miles (80 km) south of Onor, and a few miles up the Coondapoor estuary (now Varahi), was the town of Barcelore (now Basrur). Building their fortress downstream of the existing Hindu town in order to control any approaches from the sea, the Portuguese provided accommodation for 30 casados within its walls;[43] another 35 casados and their families lived in a walled compound at a stone's throw. Barcelore became a busy trading centre which exported rice, local textiles, saltpetre, and iron from the interior regions and imported corals, exotic yard goods and horses.

Fifty miles south of Barcelore was Mangalore, the last of the Portuguese strongholds in Kanara; it was situated on the mouth of the Netravati River. There too the Portuguese built a fortress and alongside it a walled town with accommodation for 35 casados families. Both Barcelore and Mangalore became principal ports for the export of rice, and during the first half of the 17th century supplied the other strategic fortalezas of significance to the Estado da India, the Portuguese Asian empire.[44][43] These included, Goa, Malacca, Muscat, Mozambique and Mombasa."
