and mentioned in the Old Javanese eulogy of Nagarakretagama by the name "Solot". After that, it became part of the Bruneian Empire before gaining its own independence on 1578. The region then became part of the independent Sultanate of Sulu, founded in 1405. The arrival of Western powers later became a conflict when the Spanish start to impose the rule of Spanish East Indies over the Sulu Archipelago. Spanish military expeditions against the sultanate were launched over the centuries of the colonial Philippines period (1565–1946). The Moro Rebellion (1899–1913) independence movement continued the Islamic Moro conflict, against the United States occupation in areas of the Moro people in the archipelago and southwestern Philippines. 1405–1844: Sulu Sultanate and Spanish East Indies The Sulu Archipelago was part of the Islamic Sultanate of Sulu, founded in 1405 by Shari’ful Hashem Syed Abu Bak’r. The sultanate also included portions of Borneo, Mindanao, Palawan, and other islands in the region. From the first Spanish encounters with Jolo island, the Spanish–Moro conflict met firm and organised resistance from the Sultanate of Sulu. Miguel López de Legazpi had established a colony in Cebu in May 1565, however the initial focus of the Spanish conquest to establish the Spanish East Indies was northwards. In June 1578 Francisco de Sande, Governor-General of the Spanish East Indies, dispatched captain Esteban Rodríguez de Figueroa and the Jesuit priest Juan del Campo and the coadjutor Gaspar Gómez to Jolo, resulting in a negotiated compromise where the Sulu sultan paid a regular tribute in pearls. The following year, Figueroa was awarded the sole right to colonise Mindanao. In 1587, during a campaign against Borneo launched by Sande, Figueroa attacked and burned down Jolo. The Spaniards left Jolo after a few days. The Joloanos resolved to resist Spanish intrusions. In response to attacks, Joloanos raided Spanish settlements and reducciones. In 1593, the first permanent Roman Catholic mission was established on the Zamboanga Peninsula, and three years later, the Spanish Army launched another attack on Jolo, which was repelled by the army of Rajah Bongsu. In November 1593, the Spanish Empire sent Juan Ronquillo to Tampakan to thwart the slave raiders. The following year, the Spanish Army troops relocated to Caldera Bay (Recodo), Mindanao. In 1598, another expedition was launched against Jolo, but was repelled by the Joloanos. In late 1600, Captain Juan Gallinato with a group of about 200 Spanish soldiers attacked Jolo but
