Well, it's biblical !
Kingdom of Israel / Judah was founded between 1030 -1010 BC
That bit on the map called Philistia (Palestine) contains modern day Gaza.
According to history (biblical and other sources), Jerusalem was sacked by the Babylonians 586 BC, and the Jews were displaced / enslaved. They returned and were again displaced / and half a million massacred by the Romans in 135 AD after the Bar Kokhba revolt along with the very early Christians. Then the Muslims conquered all of the Levant in the 7th century AD followed by the Christian crusaders, Mongols, Ottomans, Egyptians and retook by the Ottomans with British help.
