Israel and the Palestinians have been at odds since the founding of Israel in 1948. After World War II (1939-1945) and the Holocaust, in which 6 million European Jews were killed, many nations embraced the idea of creating a Jewish state in British-ruled Palestine. (The region was the historical homeland of the Jewish people.) As Jews began moving to the area in increasing numbers, tensions erupted between them and the Palestinians, most of whom are Muslim.
In 1947, a year before British rule over Palestine was set to end, the United Nations (U.N.) voted to divide the area into a Jewish state and an Arab state (see key dates, below). The U.N. partition plan designated Jerusalem as a special international zone, not belonging to either country.
Jews accepted the plan, and the following year they founded the nation of Israel, which later became a key U.S. ally. Arab leaders rejected the partition plan.
In 1948, Israel’s Arab neighbors attacked. Israel survived and, in the course of the war, seized control of western Jerusalem. Two decades later, during the Six-Day War in 1967, Israel captured the rest of Jerusalem, along with other territories. Israel has controlled the entire city ever since.
