Affonso de Albuquerque (Alhandra ca. 1453 – December 16, 1515, at sea), commonly known as Affonso the Great, “O Grande” (Portuguese: Afonso de Albuquerque, also spelled Aphonso d’Albuquerque and Alfonso), was a Portuguese general, and a “great conqueror”, a statesman, and empire builder. Albuquerque advanced the three-fold Portuguese grand scheme of combating Islam, spreading Christianity and securing the trade of spices and the establishment of a Portuguese Asian empire. Among his achievements, Afonso was the first European to enter the Persian Gulf and led the first voyage by a European fleet into the Red Sea. His military and administrative works are generally regarded as among the most vital to building and securing the Portuguese Empire in the Orient, the Middle East, and the spice routes of the Eastern Oceania. Albuquerque is generally considered a military genius, and “probably the greatest naval commander of the age” given his successful strategy: he attempted to close all the Indian Ocean naval passages to the Atlantic, Red Sea, Persian Gulf, and to the Pacific, transforming it into a Portuguese mare clausum established over the opposition of the Ottoman Empire and its Muslim and Hindu allies. In the expansion of the Portuguese Empire, Albuquerque initiated a rivalry that would become known as the Ottoman–Portuguese war, which would endure for many years. Many of the Ottoman–Portuguese conflicts in which Albuquerque was directly involved took place in the Indian Ocean, in the Persian Gulf regions for control of the trade routes, and on the coasts of India. It was Albuquerque’s military brilliance in these initial campaigns against the much larger Ottoman Empire and its allies that enabled Portugal to become the first global empire in history. He had a record of engaging and defeating much larger armies and fleets. For example, his capture of Ormuz in 1507 against the Persians was accomplished with an army fifty times smaller. Other famous battles and offensives led by Albuquerque include the conquest of Goa in 1510 and the capture of Malacca in 1511. He became admiral of the Indian Ocean, and was appointed head of the “fleet of the Arabian and Persian sea” in 1506. During the last five years of his life, he turned to administration, where his actions as second governor of Portuguese India were crucial to the longevity of the Portuguese Empire. He pioneered European sea trade with China during the Ming Dynasty with envoy Rafael Perestrello, also Thailand with Duarte Fernandes as envoy, and with Timor, passing through Malaysia and Indonesia in a voyage headed by António de Abreu and Francisco Serrão. He also aided diplomatic relations with Ethiopia using priest envoys Joao Gomes and João Sanches, and settled diplomatic ties with Persia, during the Safavid dynasty. He became known as “the Terrible”, “the Great”, “the Caesar of the East”, “Lion of the Seas”, and “the Portuguese Mars”.
