There is no “Palestinian” people ever mentioned, not even by the Romans that invented the term, not in the Bible, not in other ancient records, not in the 19th century – only since Yasser Arafat.
They are the Arabs who call themselves Palestinians.
They are indistinguishable from those Arabs who live in the surrounding artificial states such as Iraq, Jordan, Saudi Arabia or the other entities throughout the Middle East created by the colonial powers, France and Britain. Both powers were victorious after the Ottoman Turkish Empire lay defeated at the end of World War I.
Both of these European powers carved artificial borders across the corpse of what had been Turkey’s empire in the Middle East, and both France and Britain have left a resulting legacy of war and violence ever since. One such territory, previously occupied by Ottoman Turkey for 400 years, was the geographical entity known sometimes as Palestine.
But there is no such thing as a Palestinian people; no such thing as a Palestinian history; and no Palestinian language exists. There has never been any independent, sovereign Palestinian state in all of recorded history — let alone an Arab independent state of Palestine.
