Boheyat, or Abu Hayat, was born to Sultan Bayan Sirrullah and his main consort, a daughter of Sultan al-Mansur of Tidore. He was only a minor when his father passed away in 1521, allegedly poisoned. Before his death the old Sultan had instructed his consort to keep the friendship with the Portuguese, of whom some had stayed on Ternate since 1512. The Portuguese seafarers were in an expansive phase and kept the vital trading city Melaka since 1511. The enormous potential profits in the spice trade made Maluku interesting for a permanent establishment. Bayan Sirrullah saw their presence in Ternate as advantageous for the advancement of Ternate's power, not least with regard to their superior weapon technology. After his demise, Boheyat was enthroned, but real power rested with the queen Mother and the regent Kaicili Darwis, born from a co-wife of Bayan Sirrullah.
The Portuguese captain António de Brito began the construction of a fortress on Ternate in 1522, which was named São Jõao Bautista. According to agreement, the spice trade was left to the Portuguese, where a certain price was fixed for the cloves. This arrangement soon made for grass abuses, however. Resentment grew from other causes as well. The father of the widowed queen, the Sultan of Tidore, passed away in 1526, seemingly poisoned by a Portuguese physician. According to Malukan customs, peace should be kept during the first 40 days after the passing of a ruler. The Portuguese nevertheless staged an attack on Tidore and ruined the place. The arrival of new white foreigners added to the regional instability. Tidore had bonded with the remnants of the Magellan expedition in 1521 and hoped for Spanish reinforcements to counter the Portuguese and Ternatan rivals. In fact a Spanish ship appeared in 1527, whose crew was welcomed with open arms by the Tidorese. The newcomers oversaw the construction of a fort on Tidore; however, the Spanish bases in the Americas were too far away, and the Tidore-Spanish alliance only had substantial consequences after the founding of the Spanish Philippines. The other Malukan kingdoms also let themselves be involved in the rivalries between Spain-Tidore and Portugal-Ternate, since Bacan took Ternate's side and Jailolo on Halmahera supported Tidore.
Increasing tension
The regent Kaicili Darwis was an important ally of the Portuguese for several years. He balanced the influence of the Queen Mother from Tidore, who had ambitions to unite Tenate and Tidore under one of her sons and had some support in both places. However, Darwis fell out with the new captain Jorge de Menese who arrived in 1527. Menese grossly insulted the religious feelings of the Muslim Ternatans and treated even aristocrats with utter contempt. In this tense situation, Boheyat died, still an adolescent, in 1529, after having spent his reign as the virtual prisoner of the Portuguese. There were suspicions about his death being due to poisoning. He was succeeded by his full brother Dayal, under whom the relation between Menese and Darwis came to a complete rift.
