Muqrin ibn Zamil, the ruler of eastern Arabia, including al-Hasa, al-Qatif, and Bahrain, and the last Jabrid ruler of Bahrain, is defeated in battle by an invading Portuguese force that conquers the islands of Bahrain in 1521.
Having been captured in battle, King Muqrin dies from his wounds several days later.
The Portuguese commander, António Correia, will later depict King Muqrin's bleeding head on his family's coat of arms.
