[2] According to the Spanish historian Bartolomé Leonardo de Argensola (1609) he was instead the brother and successor of a Sultan called Gava who was murdered on a state visit to Ternate.
[7] The contemporary chronicler Gabriel Rebello, on the other hand, says that the Sultan formally abdicated in favour of his junior brother at this time, and does not actually mention the murder.
[12] The two regents for the young ruler were not happy about the missionary forays which could have disruptive effects, since Tidore was presently involved in warfare, and tried to dissuade the aristocrats from conversion, at least until the kingdom had stabilized.
[13] The murder of the Ternatan Sultan Hairun in 1570 at the hands of the Portuguese led to a general uprising against the white foreigners, who were besieged in their fortress in Ternate.
[16] His valiant and strongly anti-Portuguese brother Tidore Wonge went out to support the inhabitants of the Banda Islands in 1574, but was killed in Ceram on the way, at the hands of the rash Ambon captain Sancho de Vasconcellos.
However, Gapi Baguna began to fear Babullah's growing power in Maluku, and realized that a European establishment could attract the profitable clove trade.
A kinsman called Kaicili Salama (Çalama) took the challenge and set over to Ternate in the middle of the night with a group of followers, armed only with their krises.
[20] When the captain made no objections to her marrying Salama, the resentful Quisaira inspired his nephew Roque Pinheiro to murder him under the promise that she would give herself to him.
[22] Soon after the successful escape, a hundred Portuguese under Sancho de Vasconcellos arrived from Ambon in 1578 to construct a fort in Tidore, Fortaleza dos Reys Magos.
Gapi Baguna henceforth delivered 100 bahar of cloves to the Europeans each year as pareas, a kind of tribute in exchange for military protection.
[23] Although Babullah had built up a vast maritime spice empire from Mindanao to Sulawesi to the Banda Islands, he made no effort to invade Tidore since the fortress, in spite of its modesty, was strong enough to withstand an attack by indigenous troops.
[28] The news of the Iberian Union between Spain and Portugal were received in Maluku in 1582, to the consternation of Babullah, who again vainly tried to ally with Gapi Baguna against the Europeans.
In 1597, for example, Gapi Baguna asked for a Christian tailor to come to the court so that he could measure him for a shirt, but then allegedly forced him to become a Muslim, to the consternation of the Portuguese captain.
This notorious act was in fact carried out due to intrigues hatched by Sultan Saidi, who now found a good opportunity to execute his uncle and rival in 1586.
[37] Ternatan tradition says that the princess, Boki Randangagalo, was denounced by the Tidore ruler who is here called Mamolo; he left her to drift in a boat at sea, though she was rescued and brought to the Bacan Sultanate.
