From the History Channel:
King David ruled the region around 1000 B.C. His son, who became King Solomon, is credited with building the first holy temple in ancient Jerusalem. In about 931 B.C., the area was divided into two kingdoms: Israel in the north and Judah in the south.
Around 722 B.C., the Assyrians invaded and destroyed the northern kingdom of Israel. In 568 B.C., the Babylonians conquered Jerusalem and destroyed the first temple, which was replaced by a second temple in about 516 B.C.
For the next several centuries, the land of modern-day Israel was conquered and ruled by various groups, including the Persians, Greeks, Romans, Arabs, Fatimids, Seljuk Turks, Crusaders, Egyptians, Mamelukes, Islamists and others.
From 1517 to 1917, what is today Israel, along with much of the Middle East, was ruled by the Ottoman Empire.
In the late 19th and early 20th century, an organized religious and political movement known as Zionism emerged among Jews.
Zionists wanted to reestablish a Jewish homeland in Palestine. Massive numbers of Jews immigrated to the ancient holy land and built settlements. Between 1882 and 1903, about 35,000 Jews relocated to Palestine. Another 40,000 settled in the area between 1904 and 1914.
When World War I ended in 1918 with an Allied victory, the 400-year Ottoman Empire rule ended, and Great Britain took control over what became known as Palestine (modern-day Israel, Palestine and Jordan).
The British controlled Palestine until Israel, in the years following the end of World War II, became an independent state in 1947.
And of course there's more. War — or impending war — in the Middle East has become a staple of recent history.
But the who-started-it squabble is lost in the sands of millenia.
