Origins of the name.
The word "Kraich" apparently arose from the Celtic word "Creuch," meaning "mud" or "loam." The territory of a Gau (country subdivision) signifies an open area, free from woods, such as farmland or meadows.
The area of Kraichgau was first mentioned in the Early Middle Ages, in the Lorsch codex, as "Creichgowe" in the year 769. In 773, it was called "Chrehgauui," in 778 "Craichgoia."
By 1594, the name was closer to its modern form, being referred to as "Kreuchgau."
