The Samaritans

In later Hebrew writings the word Samaritan speaks of the people of the district of Samaria in central Israel. They came from intermarriages of certain Israelites with the colonists from Babylon and other parts of Mesopotamia and Syria. These colonists had been placed there by the Assyrian kings Sargon II and Esarhaddon, after the Northern Kingdom of Israel had been conquered and the stronghold at Samaria fell to the Assyrians. It resulted in thousands of Israelites being deported away, never to be heard from again, and colonists being chosen by the Assyrians and placed in Samaria along with a governor.
