The Balfour Declaration of 1917 expressed the British government's support for establishing a national home for the Jewish people in Palestine while protecting the rights of non-Jewish communities living there. This led to conflict between Jews and Arabs over control of the land in the following decades. After World War 2 and the Holocaust, the newly-formed United Nations proposed partitioning Palestine into separate Jewish and Arab states, which Jewish leaders accepted but Arab leaders rejected, leading to the 1948 Arab-Israeli war immediately following Israel's declaration of independence.
