The beginning of the use of the title sultan in Kedah is attributed to a visit by a Muslim scholar from Yemen, Sheikh Abdullah bin Ja'afar Quamiri, to Durbar Raja II's palace at Bukit Mariam in 1136.[citation needed] The audience resulted in the king's conversion to Islam. He adopted the name "Mudzaffar Shah" and established the sultanate of Kedah, which continues to rule today.[1]
