Hussein was born on 28 June 1994 in Amman to the then-Prince Abdullah and Princess Rania. Abdullah had met Rania, a marketing employee at Apple Inc., in Amman at a dinner organized by Abdullah's sister Princess Aisha in January 1993; they married six months later. Hussein is the namesake of his grandfather, King Hussein. Hussein claims descent in the male line from Muhammad's daughter Fatimah and Ali, the fourth caliph. The Hashemites ruled Mecca for over 700 years until its 1925 conquest by the House of Saud, and have ruled Jordan since 1921. The Hashemites are the oldest-ruling dynasty in the Muslim world, and are the second-oldest-ruling dynasty in the world, after the Imperial House of Japan. His paternal grandmother is an English convert to Islam, and his mother is of Palestinian descent.
