Mohammad Amin al-Husayni becomes the Grand Mufti of Jerusalem. Until late 1921, al-Husayni focused his efforts on Pan-Arabism and the ideology of the Greater Syria in particular, with Palestine understood as a southern province of an Arab state whose capital was to be established in Damascus. The struggle for Greater Syria collapsed after Britain ceded control over present day Syria and Lebanon to France in July 1920. Al-Husayni then turned from Damascus-oriented Pan-Arabism to a specifically Palestinian ideology centered on Jerusalem, which sought to block Jewish immigration to Palestine.
