This final consolidation of the Arabian Kingdom was accomplished by the end of 1925 (1345/46 AH). In the previous three years, the Sharif of Makkah had failed to maintain good relations with the British and, through his incompetence in administering the Holy Cities, had alienated much of the Arab world. Abdul Aziz ( Ibn Saud), responding to a popular demand from the people of Makkah, became the King of Hijaz and the Sultan of Nejd and its Dependencies. Ibn Saud was now ruler of most of the Arabian peninsula and Guardian of the Holy Cities of Makkah and Madinah.
