The increase in Jewish immigration and land acquisition, the growing power of Haj Amin el-Husayni, and general Arab frustration at the continuation of European rule, has radicalized increasing numbers of Palestinian Arabs by 1936.

Husayni has come to dominate the Palestinian Arab movement after a bitter clash with other nationalist elements, notably the Nashashibis, over personal rather than ideological differences.

During most of the period of the British mandate, bickering between these groups has seriously weakened the effectiveness of Arab efforts.

They achieve a measure of unity in 1936, when all the Palestinian groups join to create a permanent executive organ known as the Arab Higher Committee (AHC) under Husayni's leadership.
