who was the king of judah when jerusalem fell
Siege of Jerusalem (587 BC) Following the siege of 597 BC, the Neo-Babylonian king Nebuchadnezzar installed Zedekiah as tributary king of Judah, at the age of 21. However, Zedekiah revolted against Babylon, and entered into an alliance with Pharaoh Hophra, the king of Egypt. Nebuchadnezzar responded by invading Judah[1] and began a siege of Jerusalem in December 589 BC. During this siege, the duration of which was either 18 or 30 months,[2] the Bible describes the city as enduring horrible deprivation.[3] In 586 BC, after completion of the eleventh year of Zedekiah's reign,[4] Nebuchadnezzar broke through Jerusalem's walls, conquering the city. Zedekiah and his followers attempted to escape but were captured on the plains of Jericho and taken to Riblah. There, after seeing his sons killed, Zedekiah was blinded, bound, and taken captive to Babylon,[5] where he remained a prisoner until his death.
History of Jerusalem during the Kingdom of Jerusalem Jerusalem was conquered by the Christian First Crusade in 1099, after it had been under the Muslim rule for 450 years. It became the capital of the Christian Kingdom of Jerusalem, until it was again conquered by the Ayyubids in 1187. For the next forty years, a series of Christian campaigns (the Third, Fourth and Fifth Crusades) attempted in vain to retake the city, until Frederick II, Holy Roman Emperor leading the Sixth Crusade successfully negotiated its return in 1229. In 1244, the city was taken by the Khwarazmian dynasty and mostly destroyed. After 1250, it came under the rule of the Mamluk sultanate and was gradually rebuilt during the later 13th century.
