Explanation: In 1505, the King of Portugal appointed a governor in India for a three-year term and equipped the incumbent with sufficient force to protect the Portuguese interests.

• Francisco De Almeida, the newly appointed governor, was asked to consolidate the position of the Portuguese in India and to destroy Muslim trade by seizing Aden, Ormuz and Malacca.
• In 1507, the Portuguese squadron was defeated in a naval battle off Diu by the combined Egyptian and Gujarat navies, and Almeida’s son was killed.
• Next year, Almeida avenged his defeat by totally crushing the two navies. Almeida’s vision was to make the Portuguese the master of the Indian Ocean.
• His policy was known as the Blue Water Policy (cartaze system).
