Ahaziah was 22 years old when he began to rule, and he ruled for one year in Jerusalem. His mother was Athaliah, the granddaughter of King Omri of Israel.
The people of Jerusalem made Jehoram’s youngest son Ahaziah king in his place, because the raiders who came to the camp with the Arabs had killed all the older sons. So Jehoram’s son Ahaziah became king of Judah.
