The Davidic line refers to the descendants of David, who established the House of David (Hebrew: בֵּית דָּוִד Bēt Dāwīḏ) in the Kingdom of Israel and the Kingdom of Judah. In Judaism, the lineage is based on texts from the Hebrew Bible, as well as on later Jewish traditions.
According to the biblical narrative, David of the tribe of Judah engaged in a protracted conflict with Ish-bosheth of the Tribe of Benjamin after the latter succeeded his father Saul to become the second king of an amalgamated Israel and Judah. Amidst this struggle, Yahweh had sent his prophet Samuel to anoint David as the true king of the Israelites. Following Ish-bosheth's assassination at the hands of his own army captains, David officially acceded to the throne around 1010 BCE, replacing the House of Saul with his own and becoming the Israelite third king. He was succeeded by his son Solomon, whose mother was Bathsheba. Solomon's death led to the rejection of the House of David by most of the Twelve Tribes of Israel, with only Judah and Benjamin remaining loyal: the dissenters chose Jeroboam as their monarch and formed the Kingdom of Israel in the north (Samaria); while the loyalists kept Solomon's son Rehoboam as their monarch and formed the Kingdom of Judah in the south (Judea). With the success of Jeroboam's Revolt having severed Israel's connection to the House of David, only the Judahite monarchs, except Athaliah, were part of the Davidic line.
