He is traditionally said to have been born on 10 February 1528, though it might have been much later since his father
Hairun is stated by Portuguese sources to have been born in c. 1522.
Kaicili (prince) Baab was the oldest, or one of the oldest, sons of Sultan
Hairun (r. 1535–1570) by his consort Boki Tanjung from
Bacan. According to some versions his mother was the daughter of Sultan Alauddin I of
Bacan, while others say she came from
Mandioli west of Bacan Island. Little is known about his childhood, except that his father fostered his religious training; he was taught to "preach to the people", meaning that he received a thorough knowledge of the Qur'an. Prince Baab and his brothers were apparently trained by a
mubaligh (Islamic scholar) and a military expert in which they gained an understanding of the sciences of religion as well as warfare. According to the later chronicle of Naïdah, he was the foster son of the Sultan of Bacan. Since boyhood he also accompanied his father, following him in his temporary exile to
Goa in 1545–1546. Later he helped him to run the affairs of government and the sultanate, and co-signed an act of vassalage in 1560 - the oldest preserved Indonesian letter with seals. He is known in contemporary Portuguese sources as the heir to the throne (
herdeiro do reino), though certain later sources say that he had one or two brothers with more legitimate claims. ,
Tractado de las drogas y medicinas de las Indias orientales, 1578. Ternate, an important center for the
trade in
cloves, had been heavily dependent on the Portuguese since 1522, when they built a stone fort on the island. The Ternatan elite at first cooperated with the
Catholic foreigners whose superior weaponry and possession of the trading entrepôt of
Melaka made them useful allies. However, the behavior of the Portuguese commanders and soldiery soon evoked resentment. Sultan Hairun lived in an uneasy relationship with the Portuguese captains who nevertheless assisted him in defeating the other sultanates in
North Maluku,
Tidore and
Jailolo. A Ternatan-Portuguese conflict broke out in the 1560s, since Muslims in
Ambon appealed for assistance from the Sultan against the Europeans, who at this time were bent on Christianizing the island. Sultan Hairun sent a war fleet under Prince Baab who appeared before the Christian village Nusaniwi in 1563 and demanded its surrender. However, the siege had to be lifted as three Portuguese ships appeared. For a time after 1564, the Portuguese were forced to leave Ambon altogether, although they came back and established a stronghold in 1569. Moreover, Baab undertook an expedition to the northern parts of Sulawesi in 1563 in order to bring these lands under his father's realm. The Portuguese authorities in Maluku understood that this would be paired with the dissemination of Islam and therefore detrimental to their position in the East Indies, and efforts were made to convert populations in
Menado,
Siau Island,
Kaidipang,
Toli-Toli, etc. to Christianity. In spite of all these conflicts, the Ternate-Portuguese relationship was not entirely broken. The officer Gonçalo Pereira Marramaque led an expedition to the
Philippines in 1569, where the rulers of Tidore, Bacan and Ternate were summoned to participate. Prince Baab showed up with fifteen
korakoras (large outriggers). However, since Ternate had little interest in this venture, Baab diverted on the way and brought his fleet to the
Melaka Straits where he performed acts of piracy. He nevertheless lost 300 men in the enterprise. The Portuguese enterprise in the Philippines likewise turned out to be a failure, to the ill-concealed satisfaction of Hairun. Still, Baab was discontent with his father being too indulgent towards the Europeans. , late 16th century. == The death of Sultan Hairun ==
