The Breisgau (German pronunciation: [ˈbʁaɪ̯sɡaʊ̯] (listen)) is an area in southwest Germany between the Rhine River and the foothills of the Black Forest. Part of the state of Baden-Württemberg, it centers on the city of Freiburg im Breisgau. The district of Breisgau-Hochschwarzwald, which partly consists of the Breisgau, is named after the Black Forest area. Parts of the Breisgau are also situated in the political districts of Freiburg im Breisgau and Emmendingen.
The earliest historically attested inhabitants were Celts. In Roman times, the area was part of the province of Germania Superior, but after the rupture of the limes Germanicus in 260, the area was settled by the Alemanni. It remained a part of Alemannia throughout the Early Middle Ages and was a buffer zone between the central Alemannic lands and Alsace, which was less strongly colonized by the Alemanni.
In the mid-9th century, it was a march-like county guarding the frontier with southern Lotharingia and Alsace. In 859, it was bestowed on Charles the Fat, the son of King Louis I, a sign of its importance. In the 10th century, the Breisgau was a county within the Duchy of Swabia, ruled by the Zähringen family. In the 12th century, they detached themselves from Swabia, establishing the Margraviate of Baden. In the Breisgau, the dukes of Zähringen founded Freiburg, which became their chief city.
From the 13th/14th century to 1797, the area was part of the Vorlande, the area in southwest Germany ruled by the Austrian Habsburgs, but the Breisgau, along with the rest of the Vorlande, was ceded by them to the former Duke of Modena, a relative, as compensation for his loss of his hereditary lands to the French Cisalpine Republic. In 1805, by the Treaty of Pressburg, the area was ceded to the Grand Duchy of Baden.
