Baasha (bâ'a-shah), wickedness, or, as some suppose, in the work. Son of Ahijah, of the tribe of Issachar. He was probably of mean origin. At the siege of Gibbethon, he conspired against Nadab, king of Israel, killed him and all his family, and possessed himself of the throne. He attempted to fortify Raman, with a view, it would seem, of preventing the access of the Israelites into Judah, 1 Kings 15:17, but his design was frustrated by a Syrian invasion, instigated by Asa, king of Judah. Baasha's evil conduct provoked the denunciation of God's judgments upon his house, as predicted by Jehu the prophet. He reigned 24 years, 953-930 B. c, and was buried in Tirzah, his capital. 1 Kings 15:16-22; 1 Kings 16:1-7; 1 Kings 21:22; 2 Chronicles 16:1-6; Jeremiah 41:9.
