Adonijah was a son of David who attempted to secure the throne near the end of his father's life but was displaced when David publicly established Solomon as successor.
Biography
Adonijah, son of Haggith, was born after Absalom and became a leading claimant to David's throne. As David aged, Adonijah exalted himself, gathered chariots and supporters, and held a sacrificial feast with Joab and Abiathar while excluding Solomon, Nathan, Zadok, and David's mighty men. Nathan and Bathsheba informed David, who ordered Solomon immediately anointed and enthroned. Adonijah sought sanctuary at the altar and was initially spared after pledging good conduct. After David's death, however, he asked Bathsheba to obtain Abishag the Shunammite as his wife. Solomon interpreted the request as a renewed dynastic claim and ordered Adonijah's execution.
Biblical Significance
Adonijah's failed bid for kingship forms the immediate background to Solomon's accession. His story illustrates the political danger surrounding royal succession in David's household.
