From 1920-1948 a ( class ‘A’ Mandate) State of Palestine existed as per international law but it was, as all of its major institutions, Jewish. Until the 1960s, name “Palestine” resonated as something Jewish to European ears; the Muslims rejecting the name saying it didn’t belong. The 4,000 year old Jewish homeland or “Land of Israel” or the “Holy Land” were all synonymous!!
