The British mandate officially comes into force…

The British mandate officially comes into force on September 29, 1923, making Palestine a distinct political entity for the first time in centuries.

This creates problems and challenges for Palestinian Arabs and Zionists alike.

Both communities realize that by the end of the mandate period size of population and ownership of land will determine the region's future. (Thus, the central issues throughout the mandate period are Jewish immigration and land purchases, with the Jews attempting to increase both and the Arabs seeking to slow down or halt both.)
