In the Near East, the first half of this century was dominated by the Neo-Babylonian or Chaldean empire, which had risen to power late in the previous century after successfully rebelling against Assyrian rule. The Kingdom of Judah came to an end in 587 BC when Babylonian forces under Nebuchadnezzar II captured Jerusalem, and removed most of its population to their own lands. Babylonian rule was toppled however in the 540s, by Cyrus, who founded the Persian Empire in its place. The Persian Empire continued to expand and grew into the greatest empire the world had known at the time.
