Further Austria in the context of "William of Austria"

The Erblande ("Hereditary Lands") of the House of Habsburg formed the Alpine heartland of the Habsburg monarchy. They were the hereditary possessions of the Habsburgs within the Holy Roman Empire from before 1526. The Erblande were not all unified under the head of the dynasty prior to the 17th century. They were divided into several groupings: the Archduchy of Austria, Inner Austria, the County of Tyrol, and Further Austria.

The Erblande did not include either the Lands of the Bohemian Crown or the Lands of the Hungarian Crown, since both monarchies were elective when the Habsburg Ferdinand I was elected to their thrones in 1526. Ferdinand divided the Erblande between his three heirs in 1564 and they were not reunited until 1665. The Erblande were gathered into the Austrian Circle in 1512. This ensured a direct connection between the junior lines of the Austrian Habsburgs and the Empire after 1564, since throughout this period the Austrian Habsburgs exercised only one vote in the Council of Princes.

Büsingen am Hochrhein (German: [ˈbyːzɪŋən ʔam ˈhoːxʁaɪn], lit. 'Büsingen on the High Rhine'; Alemannic: Büesinge am Hochrhi, pronounced [ˈbyəzɪŋə am ˈhoːçri]), often known simply as Büsingen, is a German municipality (7.62 km [2.94 sq mi]) in the south of Baden-Württemberg with a population of about 1,548 inhabitants. It is an exclave of Germany and Baden-Württemberg, and an enclave of Switzerland, entirely surrounded by the Swiss cantons of Schaffhausen, Zürich, and Thurgau. It is separated from the rest of Germany by a narrow strip of land (at its narrowest, about 680 m [2,230 ft] wide) containing the Swiss village of Dörflingen. Büsingen is approximately 5 km (3.1 mi) from the town of Schaffhausen and 3 km (1.9 mi) from Dörflingen, the nearest village. Its status as an exclave dates to before the formation of the modern German and Swiss states, having previously been a detached part of Further Austria, the Kingdom of Württemberg and the Grand Duchy of Baden.

Politically, Büsingen is part of Germany, forming part of the district of Konstanz, but, economically, it forms part of the Swiss customs union, along with the principality of Liechtenstein and up until 2019, albeit unofficially, the Italian village of Campione d'Italia. As such, there have been no border controls between Switzerland and Büsingen since 4 October 1967.

The Austrian Circle (German: Österreichischer Reichskreis) was an imperial circle of the Holy Roman Empire. It was one of the four imperial circles created by decree after the 1512 Diet at Cologne, twelve years after the original six Circles were established in the course of the Imperial Reform. It roughly corresponds to present-day Austria (except for Salzburg and Burgenland), Slovenia, and the Trentino-Alto Adige/Südtirol and Venezia Giulia regions of Northern Italy, but also comprised the Further Austrian territories in the former Swabian stem duchy.

The Circle of Swabia or Swabian Circle (German: Schwäbischer Reichskreis or Schwäbischer Kreis) was an imperial circle of the Holy Roman Empire established in 1500 on the territory of the former German stem-duchy of Swabia. However, it did not include the Habsburg home territories of Swabian Austria, the member states of the Swiss Confederacy nor the lands of the Alsace region west of the Rhine, which belonged to the Upper Rhenish Circle. The Swabian League of 1488, a predecessor organization, disbanded in the course of the Protestant Reformation and the Thirty Years War in the sixteenth and seventeenth centuries.
