There has never been an independent Palestinian state in the history of the world.
The region was under the rule of the Ottoman Empire until 1918. It was conquered by the British during WWI. The original partition plan, accepted by the Jews and rejected by the Muslims, would have given the totality of the Holy Land to the Muslims.
The thing that happened was the Holocaust.
The things that happened after that, which resulted in the small expansion of Israel, were attempts at new Holocausts by neighboring Muslim states.
