Babylonians

Babylonians are an ancient nation from what is modern-day iraq and syria, that is mentioned in the Bible; mostly in the context of colonizing the Ancient Kingdom of Judah and bringing it to it's temporal end by exiling the Jews to Babylonia and Persia for 68 years in two waves (the first one of only the elites and upper-middle class in 597 and the second of the general population in 586 BC).

Biography
The Babylonians are humoristically mentioned as candidates for the ones who built the Pyramids of Ancient Egypt in "Cartman's Mom is Still a Dirty Slut".
