Sultan Babullah (10 February 1528 (?) – July 1583), also known as Sultan Baabullah (or Babu [Baab] in European sources) was the 7th Sultan and 24th ruler of the Sultanate of Ternate in Maluku who ruled between 1570 and 1583. He is known as the greatest Sultan in Ternatan and Moluccan history, who defeated the Portuguese occupants in Ternate and led the Sultanate to a golden peak at the end of the 16th century. Sultan Babullah was commonly known as the Ruler of 72 (Inhabited) Islands in eastern Indonesia, including most of the Maluku Islands, Sangihe and parts of Sulawesi, with influences as far as Solor, East Sumbawa, Mindanao, and the Papuan Islands. His reign inaugurated a period of free trade in the spices and forest products that gave Maluku a significant role in Asian commerce.
