Musa Kazim Pasha al-Husayni (, ) (1853 – 27 March 1934) held a series of senior posts in the Ottoman administration. He belonged to the prominent al-Husayni family and was mayor of Jerusalem (1918–1920). He was dismissed as mayor by the British authorities and became head of the nationalist Executive Committee of the Palestine Arab Congress from 1922 until 1934. His death was believed to have been caused by injuries received during an anti-British demonstration. Ottoman career Born in Jerusalem, as a boy Musa Kazim was sent to Istanbul and attended the Maktab Malkiya (State School) and graduated third amongst students from all over the Ottoman Empire. His first posting was in the Department of Health, but he was quickly promoted in an exceptionally successful career and was given the title Pasha. He became Governor of a series of Ottoman municipalities and regions. These included Safed, Akkar, Irbid, Asir, Najd, Thalis, Hauran. His highest position was as Governor of the al-Muntafaq region of Iraq. His status can be judged by his purchase in 1872 of 1,000 acres of fertile land around Jericho, amounting to two thirds of the farm land in the area. In 1905 he was the governor (kaymakam) of Jaffa.<ref>Pappé, Ilan (2002) 'The Rise and Fall of a Palestinian Dynasty. The Husaynis 1700–1948.

Mandate career In 1918 the British Military Governor of Jerusalem, Ronald Storrs, appointed Musa Kazem as mayor of the city. His brother, Hussein al-Husayni, had been mayor for eight years to 1918 and had died shortly after the surrender of the city to the British. Initially Musa Kazem's relationship with Storrs was good. He spoke English fluently and joined the Governor's pet project, The Association for Jerusalem, which was set up to raise the architectural standards of city buildings. In November 1918 he led a public demonstration against British policy for the first time. It was to protest the jailing of two Arabs following disturbances during counter-demonstrations over Jewish celebrations of the anniversary of the Balfour Declaration.Segev, Tom (2000) One Palestine, Complete – Jews and Arabs under the British Mandate.
