The term “Palestine” was invented by the Romans as a means to dishonor the Jews, because they hated them. They wanted to file the Jews and the Arabs together in a land called “Palestine” instead of Israel. So really, the “Palestinians” are just Jordanian Arabs that have lived in the region since the great dispersion and, in my opinion, have no rightful claim to the land whatsoever. Now let’s get back to the topic, unusual stuff.
You’re quite right, dabaron. “Palestine” was what Emperor Hadrian named Judea (omdern day Israel) after the second revlot against Rome in 135 CE. It came from the extinct nation of the Philistines. Hadrian hoepd that by naming Judea and all its cities after extinct nations, he could eventually make the Jews extinct. He failed.
