Where they also employed itinerant Arabs from throughout the Middle East to work on those very settlements. These Arabs without Historical roots in the Levant are the progenitors of the bulk of the so-called "Palestinian people" today.
Palestinian nationalism then generally subsumed under the title Arab nationalism but soon to assume its more particularistic title began to flourish at about the same time.
No, Arab Jew hatred, which later metastasized as the fraudulent movement of "Palestinian nationalism" didn't gain momentum until after Turkish rule was broken by the British toward the end of WWI.
Huh?
