Upper Alsace
Upper Alsace (southern Alsace) was a landgraviate of the Holy Roman Empire centred on Ensisheim and Landser, north of the County of Ferrette (Pfirt). The counts of Habsburg ruled the territory from the 1130s down to its cession to France in the 17th.
Albert III, Count of Habsburg, received the landgraviate of Upper Alsace from the Emperor Frederick I in 1186. Frederick's son, Duke Frederick V, was his lord with the title of Duke of Aslace (Elisatiae dux).
On 9 May 1469, Duke Charles the Bold of Burgundy acquired the landgraviate of Upper Alsace and the county of Ferrette for 50,000 Rhenish florins. At the time of its purchase, the landgraviate was heavily mortgaged and pawned. Landser was mortgaged to Thüring von Hallwill for 7,000 florins. On 20 September Charles appointed Peter von Hagenbach as the "grand bailiff (Landvogt) of Ferrette and Alsace" with his seat at Ensisheim. This official was a successor of the previous Austrian-appointed Landvogt, and thus in the service of the landgrave of Upper Alsace. The Landvogtei (bailiwick) of Alsace itself was an imperial office then mortgaged to the Electoral Palatinate.
