Gau (country Subdivision)
Gau (plural Gaue, Dutch: gouw, Frisian: gea or goa, Gronings and Old Frisian: go) is a German term for a region within a country, often a former or actual province. It was used in medieval times, when it can be seen as roughly corresponding to an English shire. The administrative use of the term was revived as a subdivision during the period of Nazi Germany in 1933–1945. It still appears today in regional names, such as the Ambergau.
