Further Austria, Outer Austria or Anterior Austria (, formerly die Vorlande (pl.)) was the collective name for the early (and later) possessions of the House of Habsburg in the former Swabian stem duchy of south-western Germany, including territories in the Alsace region west of the Rhine and in Vorarlberg. While the territories of Further Austria west of the Rhine and south of Lake Constance (except Konstanz itself) were gradually lost to France and the Swiss Confederacy, those in Swabia and Vorarlberg remained under Habsburg control until the Napoleonic Era. Geography Further Austria mainly comprised the Alsatian County of Ferrette in the Sundgau, including the town of Belfort, and the adjacent Breisgau region east of the Rhine, including Freiburg im Breisgau after 1368. Also ruled from the Habsburg residence in Ensisheim near Mühlhausen were numerous scattered territories stretching from Upper Swabia to the Allgäu region in the east, the largest being the margravate of Burgau between the cities of Augsburg and Ulm. During the Habsburg monarchy they were humorously called "tail feathers of the Imperial Eagle". Some estates in Vorarlberg possessed by the Habsburgs were also considered part of Further Austria, though they were temporarily directly administered from Tyrol. History The original home territories of the Habsburgs, the Aargau with Habsburg Castle and much of the other original possessions south of the High Rhine and Lake Constance were already lost in the 14th century to the expanding Swiss Confederacy after the battles of Morgarten (1315) and Sempach (1386). These territories were never considered part of Further Austria – except for the Fricktal region around Rheinfelden and Laufenburg, which remained a Habsburg possession until 1797. From 1406 until 1490 Further Austria together with the Habsburg County of Tyrol was included in the definition of "Upper Austria" (Oberösterreich, not to be confused with the modern Austrian state of Upper Austria). From 1469 to 1474 Archduke Sigismund gave large parts in pawn to the Burgundian duke Charles the Bold. At the Treaty of Westphalia in 1648, the Sundgau became part of France. After the Ottoman wars many inhabitants of Further Austria were encouraged to emigrate and settle in the newly acquired Transylvania region, people that later were referred as Danube Swabians. In the 18th century, the Habsburgs acquired a few minor new Swabian territories, such as Tettnang in 1780. In the reorganization of the Holy Roman Empire in the course of the French Revolutionary
