Baasha, son of Ahijah, was the third king of the northern kingdom of Israel, reigning from approximately 909 to 886 BC. His rise to power was marked by violence, as he assassinated Nadab, the son of Jeroboam, during a military campaign against the Philistine city of Gibbethon (1 Kings 15:27-28). Following this coup, Baasha exterminated the entire house of Jeroboam, fulfilling the prophecy spoken by the prophet Ahijah (1 Kings 15:29).

Baasha's reign was characterized by continued idolatry and conflict with the southern kingdom of Judah. He perpetuated the sins of Jeroboam, leading Israel into further idolatry and provoking the anger of the LORD (1 Kings 15:34). His actions drew the condemnation of the prophet Jehu, son of Hanani, who delivered a message from the LORD declaring the downfall of Baasha's dynasty due to his evil deeds and the bloodshed he caused (1 Kings 16:1-4).

The death of Baasha is recorded in 1 Kings 16:6 : "And Baasha rested with his fathers and was buried in Tirzah, and his son Elah reigned in his place." This passage indicates that Baasha died a natural death and was succeeded by his son Elah. However, the prophecy against Baasha's house was soon fulfilled when Elah was assassinated by Zimri, one of his officials, who then exterminated Baasha's entire family (1 Kings 16:11-12).

Baasha's legacy is one of continued rebellion against God, as he failed to heed the warnings of the prophets and led Israel further into sin. His reign serves as a reminder of the consequences of disobedience and the fulfillment of divine prophecy.
