How did the Palestinian people become refugees Are they originally from Palestine or Jordan ?

The main bulk of Palestinian refugees were created through the ethnic cleansing of Palestine at the hand of Zionist militias between 1947-1948 and the subsequent establishment of the state of Israel. This campaign of ethnic cleansing took place before and during the war of 1948, and saw approximately 800,000 Palestinians expelled from their homes, and over 530 villages being demolished. Another large wave of displacement and expulsions followed the war of 1967. Israel depends upon the displacement of these refugees and their descendants to maintain itself as an ethnocracy.
