Political differences between Iran and Israel are believed to be because of Israel’s stance, being allied to western influences even though the middle east has been monopolised by the u.n. since the fall of the Ottoman empire, and especially recently. Iran are also known to be pro-Palestinian.
The first documented account of thought to be Palestinians living in Samaria may be around the 13th Century BC. According to the biblical account, on fleeing Egypt, Israelites found foreigners living in the locality. The battle of Jericho commenced. Israelites described killing every last one of them. The thought to be migrants may have been the subject of a mandate of an early Assyrian empire.
According to records, during the as called neo-Persian empire, thought to be around 722 BC, ten tribes of Israel were led away and were settled in present day Iran. The tribes were Reuben, Simeon, Dan, Naphtili, Gad, Asher, Issachar, Zebulun, Manasseh and Ephraim. Known as the lost tribes of Israel. Nothing else much is known about them. Samaria was then repopulated by Babylonians and others.
The second migration to Samaria resulted in intermarriage with remaining Israeli residents. Samarians were thought to have carried on the Jewish faith for a while, though not many Jewish Samarians now.
