Francisco Serrão was a Portuguese explorer and a possible cousin of Ferdinand Magellan. His 1512 voyage was the first known European sailing east past Malacca through modern Indonesia and the East Indies. He became a confidant of Sultan Bayan Sirrullah, the ruler of Ternate, becoming his personal advisor. He remained in Ternate where he died around the same time Magellan died.
Fort Kastela is a ruined Portuguese fortress located at the southwest coast of Ternate. It is famous for being the first colonial fortification constructed in the Spice Islands (Maluku) of Indonesia. Built by the Portuguese in 1522, it is also referred to in different languages as São João Baptista de Ternate or Fortaleza de Ternate (Portuguese), Ciudad del Rosario (Spanish) or Gammalamma. Today it is locally known as Kastella/Kastela.
Sultan Babullah, also known as Sultan Baabullah 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.
Boheyat or Abu Hayat was the third Sultan of Ternate in Maluku, whose largely nominal reign lasted from 1521 to 1529. In his time the Portuguese strengthened their positions in Ternate.
Sultan Saidi Berkat was the eighth Sultan of Ternate in the Maluku Islands. His capital and seat of power was in the city of Ternate. He succeeded to the extensive east Indonesian realm built up by his father Sultan Babullah, reigning from 1583 to 1606. The Spanish, who colonized the Philippines and had interests in Maluku, repeatedly tried to subdue Ternate, but were unsuccessful in their early attempts. Saidi's reign coincides with the arrival of the Dutch in Maluku, which indirectly caused his deposal and exile through a Spanish invasion.
Sultan Mudafar Syah I, also spelt Muzaffar Syah, was the ninth Sultan of Ternate who ruled from 1606 to 1627. He reigned during an important transitional phase, when the Dutch East India Company gained ascendency in the Maluku Islands and began to regulate the commerce in spices. This was the beginning of the colonial subordination of Maluku that would accelerate during his successors.
Sultan Al-Mansur was the second Sultan of Tidore in Maluku islands, who reigned from at least 1512 until 1526. Certain legends associate him with the beginnings of Tidore's rule over the Papuan Islands and western New Guinea. During his reign the first visits by Portuguese and Spanish seafarers took place, which led to grave political and economic consequences for the societies of eastern Indonesia. Trying to preserve his realm in the face of Western encroachment, he finally fell victim to Portuguese enmity.
Sultan Mir ; or Amiruddin Iskandar Dulkarna'in was the third Sultan of Tidore in Maluku Islands. He had a long and troubled reign from 1526 to the 1550s where he tried to counter the hegemonic ambitions of the Portuguese and their Ternate allies. The global rivalries between Spain and Portugal characterized the period, and the two Iberian powers indiscriminately involved the spice sultanates Tidore and Ternate in their power game.
Gava was a Sultan of Tidore in Maluku Islands who ruled briefly in the years up to 1560. His fairly obscure reign was characterized by an attempt to expand Tidore's territory in Halmahera which ended with his violent demise at the hands of his rival, the Sultan of Ternate.
Sultan Gapi Baguna, also known as Sirajul Arifin, was the sixth Sultan of Tidore in Maluku Islands. He reigned from 1560 to 1599, a time of major political realignments. Due to the great expansion of Tidore's rival Ternate, the previous Tidorese hostility towards the Portuguese was changed into a strategic policy of cooperation, while the Spanish establishment in the Philippines and the Iberian Union in 1581 brought him Spanish support.
Mole Majimun was the seventh Sultan of Tidore in Maluku Islands, who reigned from 1599 to 1627. He was also known as Sultan Jumaldin or Kaicili Mole. In his time the transition to the hegemony of the Dutch East India Company (VOC) began in eastern Indonesia, though Tidore held on to its traditional alliance with the Spanish Empire.
Sultan Ngarolamo was the eighth Sultan of Tidore in Maluku Islands. He was also known as Sultan Alauddin, or Kaicili Ngaro, ruling from 1627 to 1634. Due to a combination of factors he was deposed after a short reign and was eventually killed at the instigation of the Sultan of Ternate.
Sultan Gorontalo was the ninth Sultan of Tidore in Maluku Islands, ruling from 1634 to 1639. His brief reign was caught up in the tension between the Spanish Empire and the Dutch East India Company, leading to his violent death in 1639.
Sultan Saidi was the tenth Sultan of Tidore in Maluku islands. He was also known as Magiau, and ruled from 1640 to 1657. His reign saw intermittent hostilities with Tidore's traditional rival, the Sultanate of Ternate, which included interference in an anti-Dutch rebellion in Ternate and Ambon and attempts to increase Tidorese territory in Maluku. By the time of Saidi's reign Tidore had gained a political position in parts of the Papuan territories.
The Sultanate of Jailolo was a premodern state in Maluku, modern Indonesia that emerged with the increasing trade in cloves in the Middle Ages. Also spelt Gilolo, it was one of the four kingdoms of Maluku together with Ternate, Tidore, and Bacan, having its center at a bay on the west side of Halmahera. Jailolo existed as an independent kingdom until 1551 and had separate rulers for periods after that date. A revivalist Raja Jailolo movement made for much social and political unrest in Maluku in the 19th century. In modern times the sultanate has been revived as a symbolic entity.
The Ternatean–Portuguese conflicts were a series of conflicts in the Spice Islands in eastern Indonesia between the Portuguese and their allies on one hand, and the Sultanate of Ternate and its allies, on the other. Hostilities broke out from time to time after the establishment of Portugal in Moluccas in 1522. The strongly Catholic and Muslim identities of the combatants gave the struggle elements of a war of religion, although this aspect was frequently blurred by cross-faith alliances. It was also an economic war since the Portuguese aim was to control export of the profitable trade in cloves. Portuguese-Ternatan rivalry later merged with attempts of expansion by the Spanish in the Philippines. The Portuguese were eventually defeated in 1605 by an alliance between the Dutch East India Company (VOC) and Ternate, ending their active involvement in Moluccas affairs. However, they were soon replaced by the Spanish who maintained an Iberian presence in the region up to 1663.
The Attack on Jailolo was a military expedition launched by the combined force of Spanish-Portuguese and Ternatean armies to oust the ruler of Jailolo. The attack failed.
In 1603, a military expedition was launched by a joint of Spanish-Portuguese forces to capture the city of Ternate. The expedition failed to achieve its objectives.
The Ternate expedition was a military expedition by the Spanish to establish their rule on Maluku island. The expedition failed and was the Spanish's first attempt to seize Malukus.
