What is the story of the Fall of Babylon?

Answer 1

Babel was founded by Noah's great grandson,Nimrod, but it's construction suddenly stopped when God confused their languages. (Genesis 11:9) Rebuilders came and went, Hammurabi strengthened the city under Semitic rule.
Babylon was part of the Assyrian World Power, and the Chaldean ruler, Nabopolassar, and his son, Nebuchadnezzar II rebuilt it with a new government about 645 B.C.E.(Daniel 4:30). Strong and imposing, this mighty city remained unchallenged and unconquerable, the capital of the third world power, finally conquering Jerusalem and taking the Jews as captives in 607BCE., where they remained until 539 B.C.E. (Gregorian calendar), when, as prophesied years before, Babylon fell to the Medo-Persian armies under Cyrus the Great(Jeremiah 51:30-32).
That night, Belshazzar, son of Nebuchadnezzar, held a banquet for a thousand people(Daniel 5:1) disrespectfully using utensils from God's temple for his drunken party (Daniel 5:2-4) and forgetting to guard the doors. When writing miraculously appeared on the wall, saying: "MENE, MENE, TEKEL and PARSIN" (Daniel 5:5-28) Daniel, God's prophet, translated the meaning to the king. His government would be destroyed. That night, Cyrus' army diverted the waters of the Euphrates River and walked to Babylon on the riverbed. In one night, they captured the palace, killed Belshazzar(Daniel 5:30), and Babylon had fallen. God's prophecy was fulfilled(Isa 44:26-45:7;Jeremiah 50:38) and God's people could go home to Jerusalem(2Chronicles 36:22, 23; Ezra 1:1-4) after 70 years of bondage.
