They declare their intention for a Jewish National Homeland: the Balfour Declaration
This even sparked an outbreak of violence on both sides
Begun when a British commissioner was killed. The British response was to take control of all military, execute suspected terrorists, and jail thousands of others.
The British accepted many of the demands of the Arab terrorists. They agreed to strictly limit Jewish immigration, and tighten restrictions on land sales in Palestine. The white Paper also called for a single unified state rather than a divided Palestine.
The victory by the British was at the cost of "Tens of thousands jailed, thousands killed, hundreds executed, countless houses demolished, and key leaders in exile."
This mean the Jews were to have signs outside their homes identifying them as Jews, and many of their rights were taken away.
Thousands of Jews are rounded up to be shipped on trains to concentration camps. They are only just barely saved by political maneuvering and the support of the non-Jewish Bulgarian people.
