At the beginning of14th century, Muslim merchants from Arabia and India introduced Islam to the commercial ports of sulu archipelago while trading with local merchants in Sulu. Later, under the influence of Climar Mahmoud, an Islamic teacher, some local nobles and businessmen began to believe in Islam.
About AD 1450, with the support of local Muslim nobles and businessmen, Sulu Sultanate was formally established. After the founding of the Sultanate of Sulu, it believed in Sunni doctrine and implemented an Islamic political system of integrating politics with religion.
Sulu Kingdom appeared in China's historical records very early, and its name was recorded in Dade Nanhai Zhi (1304), and its geographical position and main products were recorded in detail in Shi Ma Zhi Lu Guo (1349) written by Wang Dayuan, a famous scholar in Yuan Dynasty.
During the Yongle period of the Ming Dynasty (14 17), the three Sulu kings led 340 family members and their entourage across the ocean to China, where they were warmly received by the Yongle Emperor of the Ming Dynasty. On the way back to Texas, King Ge Badala of Dongbadu died of illness. Ming Chengzu sent a doctor of rites to Dezhou to bury Dongwang as a vassal, and also gave him a copy of Ding Gong, which was inscribed by himself (the tomb of Sulu Dongwang). After the death of Dong Wang, his eldest son returned to China to succeed him, and the princess and two other sons stayed in Texas to guard the tomb. Their descendants acquired China nationality in the Qing Dynasty and were named An and Wen. It is said that the descendants of the East King have been handed down for 2 1 generation. Later, due to several major natural disasters in history, many descendants of Dongwang left Texas and distributed in many places. Now, the descendants of the East King have already integrated into China. 1987, the film "King Sulu and Emperor China" co-produced by China and the Philippines premiered, which reappeared this story.
In A.D. 19 15, the governor of the United States in Moro province signed an agreement with Sulu Sultan Quilen II, who gave up his secular rule in Sulu and only retained the position of religious leader. Since then, Sulu has become a part of the Philippines, and Sulu Kingdom has perished.
