In 1936 unrest broke out in the British mandate of Palestine amid frustration at rising Jewish immigration in the wake of Britain’s Balfour Declaration.

Areas A, B and C
A messy patchwork of control in the West Bank and Gaza Strip, agreed in 1995 as part of the Oslo II accord. In Area A, which includes the main Palestinian towns, the Palestinian Authority was given full civil and security control.

In Area C, which includes most Jewish settlements, Israel kept full control. See map.

It is home to roughly 2.2m people, many of whom rely on international aid, and has been run by Hamas, a militant group, since 2007.
