Part one
Not at all barknmod. Prior to 1947 Israel was made up of small pockets of land within Palestine. In that year the UN Partition took place. At that point about half of Palestine was annexed to Israel. Palestine was essentially left with the area we now call the West Bank, Gaza and a small pocket of land in the northern border of Lebanon. By 1949 the land in the north was taken over. Not only Palestinians were removed but also the Druze. At that  time both the West bank and Gaza shrank in size; about the size of those areas now occupied by Palestinians. This happened after the British Mandate and the Arab-Israel War of 1948 ended. Obviously I am giving you a nutshell history lesson but you can always do some research.

Between 1949, when the State of Israel was declared, and the present day, Gaza has remained as a small pocket of land but the West Bank has been incrementally taken over by Israel with settlements, leaving pockets of land for the Palestinians.
