Palestinians is a nickname of the Arabs that lives in Israel but are not Israel citizens. There is no war between to them and the Arabs. Maybe you meant the war between the Arabs and the Jews.
20 years backward
No Jews the pyramids were built long before Israel
Jews have lived in the area (Bohemia, Moravia, Slovakia) since the Middle Ages, though there were periodic expulsions and readmissions.
They still live in former Yugoslavia republics.
A long list. Prominent among them are the Romans, the Arabs and the British.
The Arabs in general were greatly saddened by the creation of the State of Israel, because they believed that the land that had physically belonged to the Palestinian Arabs for as long as they could remember and should have been theirs for inheritance. In their minds, it did not make sense that a group of German, Polish, French, English, and Russian speaking people should claim land that their ancestors had not even visited for centuries. Even by the time of Israel's Declaration of Statehood, less than half of the land within the UN proscribed borders of Resolution 181 was owned by Jews. Therefore, the idea of Jewish State being even more physically expansive than the land already taken was alarming.
Since about AD1100.
God promised the Land of Israel (Canaan) to the descendants of Jacob in Genesis ch.28. He was renamed Israel in Genesis ch.35. Israelites, today also called Jews, have lived in Israel continually (albeit often as a minority) for the last 3000 years: Where_did_Jews_live_in_more_than_anywhere_elseDoes_Palestine_belong_to_Jews_or_MuslimsRecently, Israel became a country in 1948, but Jewish large-scale purchases of land began there a hundred years earlier.
Answer 1Primarily, the Jews historically lived in the area known as Palestine around 2000 years ago. The majority were then exiled by the Romans. The people who remained in the territory in the interim period began to consider themselves Arabs by the mid-1200s. When the British occupied the area and called it Palestine, these Arabs began to call themselves Palestinians. During this period, however, many Jews sought to return to their ancestral homeland and declare it as their own historic country. This provoked conflict between the people returning to their homeland and those who had lived there for centuries.Please see the Related Questions for more information.Answer 2the story is very long and complicated and quite frankly, the feud is pointless. in a biblical sense, some Muslim (and therefore many Arabs) believe that the Jews (/israelis) don't deserve the land of israel because in the Torah, the Jews turned in don't in fear of the Canaanites (the people that lived in that land while the Jews were enslaved in Egypt) and therefore demonstrated a lack of trust in god/El/Allah. as a result the Jews were sent into exile in the desert for 40 years. (personally i believe that the Jews have repented enough over the years and deserve their right to israel, but hey that's me) another reason of more recent history is a little somethng that took place during and after world war II. it was called the British mandate and it was when Great Britain was ruling over "palestine." the British promised the Muslims the state of Palestine to be a Muslim country, and in exchange the Arabs would send support to the allied powers and then, of course the war ended and a decade or so later the british went against there promise and gave Palestine to be a sovern Jewish State, which was renamed Israel (much like Jacob from the Torah, hmm...). might i add it was very neccisary for the Jews to have a homeland which is another conversation entirely...in short, the answer to your question, as demonstrated by these facts is... HATE. yep, that's it, thousands of years of hatred. both sides are right and have just cause and yet both sides are wrong and completely out of bounds, and unfortunately, the hate is there and there really is no going back now... sorry i could give you a more uplifting answer...
Answer 1there are many different veiws on who lived there first, i say that the Jews lived in israel first...... Palestine was never a country before the Palestinians and for Saudi Arabia i have no ideaThe Hurrians, a people related to the Georgians of the Caucasus, lived in Israel (or Palestine) and Syria long before any Semite came near the area; they built the world's first dolmens in 10,000 BC; they are the Horites and Rephaim of the Bible (like Og and Goliath). In 9000 BC they built the world's first city in southern Turkey. They spoke a Kartvelian language. Northern Arabia was most likely inhabited by Hurrian relatives (around 10,000 BC) and southern Arabia was entirely Nilotic African. In 10,000 BC, an African tribe called the Nostratic people invaded southern Arabia from Ethiopia and eventually ended up on the southern shore of the Black Sea in Turkey. They were the ancestors of the Semites, Hamites, Indo-Europeans, Uralics, Altaics, and others. They brought the Adam story with them from Africa, and were the people involved in the Flood in 7300 BC.Answer 2Israel/Palestine: This area (prior to the Muslim conquest in 634-638 CE) was a Byzantine Imperial province. The majority of the population was likely Orthodox Christian with a substantial Jewish minority. The Christians would likely have identified as ethnically Byzantine, Phoenician, Canaanite, Samaritan, etc. The Jews would have identified only as Jews.Saudi Arabia: The dominant population in Saudi Arabia since time immemorial was the Arabs. Prior to Islam, most Arabs were henotheists, which means that they believed in multiple gods but believed that one of those gods was superior to all of the others. Minorities of Arabs were Christians (mostly of heretical sects) and there were also a minority of Jewish Arabs.
The short answer is: about one thousand years. See the attached Related Link.
