Dezhou (Chinese: 德州; pinyin: Dézhōu) is a prefecture-level city in northwestern Shandong province, People's Republic of China. It borders the provincial capital of Jinan to the southeast, Liaocheng to the southwest, Binzhou to the northeast, and the province of Hebei to the north.
The King of Sulu Paduka Pahala from the first royal family on Sulu before the Hashemites went on a tribute mission to the Ming dynasty Yongle Emperor. He died of natural causes in China and his two sons were left in the care of Hui Muslims in Dezhou, Shandong. The two families descended from the two sons were given the surnames An and Wen by the Ming Emperors. They lived through the Ming and Qing dynasties and still live in Dezhou today.
The Kingdom of Sulu was converted to Islam, and the Hashemite Sharif ul-Hāshim of Sulu arrived in Sulu and married a princess of the previous non-Hashemite royal family, founding the Sulu Sultanate.
Tausug delegations from Sulu have visited Dezhou to see the descendants of the previous royal family.
