Where did the chaldeans originate from?

The Chaldeans originated from the region of southern Mesopotamia, specifically in what is now modern-day Iraq. They emerged as a distinct group around the first millennium BCE, primarily in the area of Babylon. The Chaldeans were known for their contributions to astronomy and mathematics, and they played a significant role in the cultural and political landscape of ancient Mesopotamia. Over time, they became associated with the Neo-Babylonian Empire, particularly during the reign of King Nebuchadnezzar II.
