Ciri Leliatu is only known from relatively late historical traditions. According to these, the four
North Malukan kingdoms
Ternate, Tidore (Duko),
Bacan and
Jailolo were founded by the four sons of the Arab Jafar Sadik. The son who inherited Tidore, Sahjati, was followed by seven rulers with the title
Kolano. The last of them was Matagena who, according to the chronicle
Hikayat Ternate, was a
Malay lord who expelled his predecessor
Kolano Sele and acquired kingship over the island. According to even later sources, he was descended from a line of Muslim
qadis and thus started a new royal lineage, and eventually died in Gotowasi village in
Halmahera. He is nevertheless counted among the pre-Islamic rulers. Matagena's son was Ciri Leliatu, also called Ciriliyati, who succeeded to the
Kolano-ship in the late 15th century. An Arab called Syekh Mansur came to Tidore and converted him to Islam, whereby he received the Islamic name Sultan Jamaluddin. The eldest son of the king was named after the preacher, and later succeeded his father as Sultan
al-Mansur. (large outrigger for warfare) in a manuscript from the 16th century. There are, however variants of the conversion story. The
Ambonese chronicle
Hikayat Tanah Hitu, written in the 17th century, says that the key figure was Mahadum, who was the son of a Sultan of
Samudra Pasai. Mahadum performed missionary work in several places in Indonesia, successively travelling to the east. From the
Banda Islands he proceeded to Jailolo on
Halmahera whose king he converted and gave the name Yusuf. From there he went to the nearby Tidore Island and won its ruler for Islam. The converted king is here called Ismail, who showed great favours to Mahadum and gave him the princess Syamai as wife. From this marriage a son Syuku was born. Finally the Kolano of Ternate heard about Mahadum and invited him to his island, letting himself be converted under the name
Zainal Abidin. Mahadum died in Ternate and his son Syuku was married to Zainal Abidin's daughter. European sources from the 16th century confirm that a wave of Islamic conversions took place in the North Malukan kingdoms in the second half of the 15th century, since many Muslim merchants from
India,
Java and the
Malay world came there to trade in
cloves which grew abundantly in Tidore. ==Contact with the Papuans==
