Just to add to the backplot…
The region of Judea (I don’t know the country name at the time) was absorbed into Alexander the Great’s empire. On his death, Judea and the surrounding provinces passed to the Seleucids based in then-current Syria. Several internal disputes later (one of which became Chanukah), the Roman Empire took over the province of Judaea (Latin spelling) along with much of the former Greek empire. After a certain period of unrest in the 1st century CE, the Romans attacked Jerusalem, destroying the Second Temple. Unrest continued sporadically for another century; a revolt attempt was crushed at Beitar in the mid-second century, and the Romans renamed the province Palestinia, after the Philistines based in Gaza (and possibly extinct by the time the Romans became a power).
Palestinia (Palestine, in English) later became part of the Byzantine empire, then was taken over by a series of Muslim powers, the last of which was the Ottoman Empire. See previous posts for the change from Ottoman to British control.
ca. 1900, Theodor Hertzl persuaded many Jews in Europe to return to Palestine and settle there. This First Aliyah settled and cultivated what was basically a wasteland, according to the Jewish history books. I ought to see what the other history books say in comparison.
As best I know, and I’m getting out of my good knowledge here, the Arabs in Palestine started identifying themselves as “Palestinians” ca. 1920. From then to after WWII, the Jewish settlers, Palestinians, and British Mandate forces had a low-level three-way fight. The British spun off the part of Palestine east of the Jordan River as the Arab country of Transjordan; I think this was during the interwar period. The UN Partition Plan of 1947 gave the Jewish-settled areas to the Jews, the Palestinian-inhabited areas to the Palestinians, and made Jerusalem an international city, not part of either side. The moment the partition went into effect in May 1948, the Arab countries attacked, essentially reducing the 3-sided war to 2-sided, as part of the partition plan was the termination of the British Mandate over Palestine.
Without getting into the realm of GD, I’ll only say that the fighting has continued ever since.
Your questions in post #4 are, I believe, in the realm of GD.
