After the April riots an event took place that turned the traditional rivalry between the Husseini and Nashashibi clans into a serious rift, with long-term consequences for al-Husseini and Palestinian nationalism. According to Sir Louis Bols, great pressure was brought to bear on the military administration from Zionist leaders and officials such as David Yellin, to have the mayor of Jerusalem, Musa Kazim Pasha al-Husayni, dismissed, given his presence in the demonstration of the previous March. Colonel Storrs, the Military Governor of Jerusalem, removed him without further inquiry, replacing him with Raghib al-Nashashibi of the rival Nashashibi clan. This, according to the Palin report, 'had a profound effect on his co-religionists, definitely confirming the conviction they had already formed from other evidence that the Civil Administration was the mere puppet of the Zionist Organization.'
