On this day February 3, 1509
The Battle of Diu, between Portugal and the Ottoman Empire takes place in Diu, India.
The naval Battle of Diu was a critical sea battle that took place on 2–February 3, 1509 between Portugal and a joint fleet of the Mamlûk Burji Sultanate of Egypt, the Zamorin of Calicut and the Sultan of Gujarat, with technical naval support from the Republic of Venice and the Republic of Ragusa (Dubrovnik).
This battle is critical from a strategic perspective since it marks the beginning of the dominance of the Europeans in the Asian naval theater. It also marks the spillover of the Christian-Islamic power struggle, in Europe and the Middle East, into the Indian Ocean which was the dominant region of international trade at that time.
The battle set the stage for domination of trade in the Indian Ocean by the Portuguese for the next century, and thus greatly assisted the growth of the Portuguese Empire.
