Answer 1

the assyrians

Answer 2

The Assyrians Wiped Out, the Medes and Chaldeans Expand. In order to secure the territory of Judah, Nebuchadnezzar brought Jehoiachin and Zedekiah, the two kings of Judah (in succession) and held them in Babylon. In keeping with Assyrian practice, the "New Babylonians," or Chaldeans forced a large part of the Jewish population to relocate. Numbering possibly up to 10,000, these Jewish deportees were largely upper class people and craftspeople; this deportation marks the beginning of the Exile in Jewish history. As you can see, the Chaldeans were called Neo-Babyloians.

Then in 555 BC Babylon came under the control of a king loyal to the Assyrians, Nabonidus (555-539 BC), who attacked Babylonian culture at its heart: he placed the Assyrian moon-god, Sin, above the Babylonian's principal god, Marduk, who symbolized not only the faith of Babylon but the very city and people itself. Angered and bitter, the priests and those faithful to Babylon would welcome Cyrus the Conqueror of Persia into their city and end forever Semitic domination of Mesopotamia.
