The Kings of Judah were the monarchs who ruled over the ancient Kingdom of Judah, which was formed in about 930 BCE, according to the Hebrew Bible, when the United Kingdom of Israel split, with the people of the northern Kingdom of Israel rejecting Rehoboam as their monarch, leaving him as solely the King of Judah.

Ahaziah of Judah or Jehoahaz I, was the sixth king of Judah, and the son of Jehoram and Athaliah, the daughter of king Ahab of Israel. He was also the first Judahite king to be descended from both the House of David and the House of Omri, through his mother and successor, Athaliah.
