The Kingdom of Judah (also known as the "Southern Kingdom") was created in c. 930 BCE on the split up of the United Monarchy. David was made king over the tribe of Judah as early as 1007 BCE, and the Davidic line was followed by Judah for over 420 years, until the Kingdom fell in 586 BCE to the Babylonian Empire under Nebuzar-adan, captain of Nebuchadnezzar's body-guard.
