Chaldea

Chaldea refers to a region in southern Mesopotamia, possibly located in the marshy land of the Euphrates and Tigris rivers. The region was inhabited by nomadic Chaldeans, who were West Semitic-speaking migrants from the Levant, and later became known as the Chaldeans or Chaldees. During the Neo-Babylonian Empire (626-539 BC), a ruling dynasty of Chaldean origin ruled the kingdom, although the final ruler, Nabonidus, was an Assyrian usurper. The name Chaldea is derived from the Akkadian māt Kaldu and is not to be confused with the modern Chaldean Catholic Church or its adherents, who are predominantly ethnic Assyrians.learn more on wikipedia
