The Chauci were an ancient Germanic tribe living in the low-lying region between the Rivers Ems and Elbe, on both sides of the Weser and ranging as far inland as the upper Weser. Along the coast they lived on artificial mounds called terpen, built high enough to remain dry during the highest tide. A dense population of Chauci lived further inland, and they are presumed to have lived in a manner similar to the lives of the other Germanic peoples of the region.
