Kingdom of Israel (Samaria)
Shechem was the first capital of the Kingdom of Israel.[14]  Afterwards it was Tirzah.[15]  King Omri built his capital in Samaria (1 Kings 16:24), which continued as such until the destruction of the Kingdom by the Assyrians (). During the three-year siege of Samaria by the Assyrians, Shalmaneser V died and was succeeded by Sargon II of Assyria, who himself records the capture of that city thus: "Samaria I looked at, I captured; 27,280 men who dwelt in it I carried away"  into Assyria. Thus, around 720 BCE, after two centuries, the kingdom of the ten tribes came to an end.
