The British occupied Hebron on 8 December 1917; governance transited to a mandate in 1920. Most of Hebron was owned by old Islamic charitable endowments ("waqfs"), with about 60% of all the land in and around Hebron belonging to the Tamīm al-Dārī waqf. In 1922, its population stood at 17,000. During the 1920s, Abd al-Ḥayy al-Khaṭīb was appointed Mufti of Hebron. Before his appointment, he had been a staunch opponent of Haj Amin, supported the Muslim National Associations and had good contacts with the Zionists. Later, al-Khaṭīb became one of the few loyal followers of Haj Amin in Hebron. During the late Ottoman period, a new ruling elite had emerged in Palestine. They later formed the core of the growing Arab nationalist movement in the early 20th century. During the Mandate period, delegates from Hebron constituted only 1 per cent of the political leadership. The Palestinian Arab decision to boycott the 1923 elections for a Legislative Council was made at the fifth Palestinian Congress, after it was reported by Murshid Shahin (an Arab pro-Zionist activist) that there was intense resistance in Hebron to the elections. Almost no house in Hebron remained undamaged when an earthquake struck Palestine on July 11, 1927.
