The most notable theological divide between Jewish and Samaritan doctrine concerns the world's holiest site, which the Jews believe is the Temple Mount in Jerusalem and which Samaritans believe is Mount Gerizim near modern Nablus and ancient Shechem
The Samaritan High Priest is the high priest (kohen gadol) of the Samaritan community in the Levant, the office has existed continuously since the time of Aaron, the brother of Moses, and has been held by 133 priests over the last 3400 years. Since 1623/24, the office of high priest has been passed down in a family traced back to Aaron's grandson Itamar. After the death of a high priest, the office passes to the oldest male in that family, unless he has entered into a marriage that disqualifies him from the high priesthood.
One account by Josephus suggests that its office holders are an offshoot of the Zadokite high priests of Jerusalem from around the time of Alexander the Great - Samareis (Σαμαρεῖς) refers to inhabitants of the region of Samaria...
Samaritans call themselves Shamerim (שַמֶרִים), meaning "Guardians/Keepers/Watchers" from Semitic root שמר, which means "to watch, guard"
Modern genetic studies support the Samaritan narrative that they descend from indigenous Israelites. Shen et al. (2004) came up with genetic evidence that Samaritans are closely linked to Cohanim, and therefore can be traced back to an Israelite population prior to the Assyrian invasion of the Israelite Kingdom of Israel in approximately 721 BCE. The annals of Sargon II of Assyria indicate that he deported 27,290 inhabitants of the former kingdom..
The Book of Chronicles records that King Hezekiah of Judah invited members of the tribes of Ephraim, Zebulun, Asher, Issachar and Manasseh to Jerusalem to celebrate Passover after the destruction of the Northern Kingdom of Israel. However, the Samaritans were generally more populous and wealthier than the Judeans in Palestine, until 164 BC
The Dead Sea scrolls' Proto-Esther fragment 4Q550c has an obscure phrase about the possibility of a Kutha(ean)(Kuti) man returning but the reference remains obscure.[47] 4Q372 records hopes that the northern tribes will return to the land of Joseph.
Following the death of Alexander the Great, the area became part of the newly partitioned Ptolemaic Kingdom, which, in one of several wars, was eventually conquered by the neighboring Seleucid Empire.
Samaritan traditions of their history are contained in the Kitab al-Ta'rikh compiled by Abu'l-Fath in 1355
