On the Arabian Peninsula, the Arabs were able to establish several independent states. In 1916 Hussein bin Ali, Sharif of Mecca, established the Kingdom of Hejaz, while the Emirate of Riyadh was transformed into the Sultanate of Nejd. In 1926 the Kingdom of Nejd and Hejaz was formed, which in 1932 became the kingdom of Saudi Arabia. The Mutawakkilite Kingdom of Yemen became independent in 1918, while the Arab States of the Persian Gulf became "de facto" British protectorates, with some internal autonomy.
