County of Bregenz
Bregenz is recorded as a county within the Holy Roman Empire between 1043 and 1160. It was in possession of the Udalrichinger, who took the titles of counts of Bregenz. After 1160, Bregenz falls to the counts of Montfort-Bregenz (1160 to 1338), a cadet branch of the counts of Montfort, Montfort-Tettnang-Bregenz (1354 to 1451). After 1451, the title of count of Bregenz is held by the House of Habsburg and Bregenz is incorporated into the duchy of Austria. The nominal title of count of Bregenz was kept as one of the titles of the Austrian emperor until 1918.
