Israel and Palestine are fighting over a century-long territorial dispute over the Holy Land, a Middle Eastern region with great religious and historical significance to Christians, Jews, and Muslims. The conflict began in the mid-20th century, and it is one of the worlds most intractable. The roots of the conflict can be traced back to the Balfour Declaration, a public statement issued by the British government in 1917 during the First World War announcing support for the establishment of a "national home for the Jewish people" in Palestine. The conflict has its origins in competing claims to the Holy Land, and includes disputes over borders, Jerusalem, security, and Palestinian refugees. The current Israeli-Palestinian status quo began following Israeli military occupation of the West Bank and Gaza in the 1967 Six-Day War, known as the Palestinian territories. The conflict has resulted in several wars, armed uprisings, and terrorist acts, causing thousands of casualties. The conflict has also led to the displacement of hundreds of thousands of Palestinians. The primary approach to solving the conflict today is a so-called “two-state solution” that would establish Palestine as an independent state in Gaza and most of the West Bank, leaving the rest of the land to Israel.
