Question: The Margraviate of the country that borders Lake Constance, besides Germany and country Karin Thomas was born, is an instance of what?

full_context: Document 1: Alps: Crossing the Italian-Austrian border, the Brenner Pass separates the Ötztal Alps and Zillertal Alps and has been in use as a trading route since the 14th century. The lowest of the Alpine passes at 985 m (3,232 ft), the Semmering crosses from Lower Austria to Styria; since the 12th century when a hospice was built there it has seen continuous use. A railroad with a tunnel 1 mile (1.6 km) long was built along the route of the pass in the mid-19th century. With a summit of 2,469 m (8,100 ft), the Great St. Bernard Pass is one of the highest in the Alps, crossing the Italian-Swiss border east of the Pennine Alps along the flanks of Mont Blanc. The pass was used by Napoleon Bonaparte to cross 40,000 troops in 1800. The Saint Gotthard Pass crosses from Central Switzerland to Ticino; in the late 19th century the 14 km (9 mi) long Saint Gotthard Tunnel was built connecting Lucerne in Switzerland, with Milan in Italy. The Mont Cenis pass has been a major commercial road between Western Europe and Italy. Now the pass has been supplanted by the Fréjus Road and Rail tunnel. At 2,756 m (9,042 ft), the Stelvio Pass in northern Italy is one of the highest of the Alpine passes; the road was built in the 1820s. The highest pass in the alps is the col de l'Iseran in Savoy (France) at 2,770 m (9,088 ft).
Document 2: Rhine: The Rhine emerges from Lake Constance, flows generally westward, as the Hochrhein, passes the Rhine Falls, and is joined by its major tributary, the river Aare. The Aare more than doubles the Rhine's water discharge, to an average of nearly 1,000 m3/s (35,000 cu ft/s), and provides more than a fifth of the discharge at the Dutch border. The Aare also contains the waters from the 4,274 m (14,022 ft) summit of Finsteraarhorn, the highest point of the Rhine basin. The Rhine roughly forms the German-Swiss border from Lake Constance with the exceptions of the canton of Schaffhausen and parts of the cantons of Zürich and Basel-Stadt, until it turns north at the so-called Rhine knee at Basel, leaving Switzerland.
Document 3: Brusio spiral viaduct: The Brusio spiral viaduct (or Brusio circular viaduct; Italian: Viadotto elicoidale di Brusio, German: Kreisviadukt Brusio) is a single-track nine-arched stone spiral railway viaduct.
Document 4: Glenfinnan Viaduct: The Glenfinnan Viaduct is a railway viaduct on the West Highland Line in Glenfinnan, Inverness-shire, Scotland. Located at the top of Loch Shiel in the West Highlands of Scotland, the viaduct overlooks the Glenfinnan Monument and the waters of Loch Shiel.
Document 5: Rhine: The Rhine (Latin: Rhenus, Romansh: Rein, German: Rhein, French: le Rhin, Dutch: Rijn) is a European river that begins in the Swiss canton of Graubünden in the southeastern Swiss Alps, forms part of the Swiss - Liechtenstein, Swiss - Austrian, Swiss - German and then the Franco - German border, then flows through the German Rhineland and the Netherlands and eventually empties into the North Sea.
Document 6: Rhine: Lake Constance consists of three bodies of water: the Obersee ("upper lake"), the Untersee ("lower lake"), and a connecting stretch of the Rhine, called the Seerhein ("Lake Rhine"). The lake is situated in Germany, Switzerland and Austria near the Alps. Specifically, its shorelines lie in the German states of Bavaria and Baden-Württemberg, the Austrian state of Vorarlberg, and the Swiss cantons of Thurgau and St. Gallen. The Rhine flows into it from the south following the Swiss-Austrian border. It is located at approximately 47°39′N 9°19′E﻿ / ﻿47.650°N 9.317°E﻿ / 47.650; 9.317.
Document 7: Anna-Karin Hesse: Anna-Karin Hesse (1 August 1961 – 14 July 1983) was a Swedish alpine skier who competed in the 1980 Winter Olympics.
Document 8: Brusio spiral viaduct: A signature structure of the World Heritage-listed Bernina railway, it is located near Brusio, in the Canton of Graubünden, Switzerland, and was built to limit the railway's gradient at that location within its specified maximum of 7%.
Document 9: Principality of Bayreuth: The Principality of Bayreuth () or Margraviate of Brandenburg-Bayreuth ("Markgraftum Brandenburg-Bayreuth") was an immediate territory of the Holy Roman Empire, ruled by a Franconian branch of the Hohenzollern dynasty. Since Burgrave Frederick VI of Nuremberg was enfeoffed with the Margraviate of Brandenburg in 1415/17, the Hohenzollern princes transferred the margravial title to their Franconian possessions, though the principality never had been a march. Until 1604 they used Plassenburg Castle in Kulmbach as their residence, hence their territory was officially called the Principality of Kulmbach or Margraviate of Brandenburg-Kulmbach until the Empire's dissolution in 1806.
Document 10: Věra Klimková: Věra Klimková (born Věra Leskovjanská on 11 August 1957 in Spišská Nová Ves) was a Czechoslovakian cross country skier who competed from 1982 to 1988. She finished seventh in the 4 × 5 km relay at the 1988 Winter Olympics in Calgary.
Document 11: Karin Thomas: Karin Thomas (born 3 October 1961 in Brusio) was a Swiss cross country skier who competed from 1982 to 1988. She finished sixth in the 4 x 5 km relay at the 1984 Winter Olympics in Sarajevo and fourth in that same event at the 1988 Winter Olympics in Calgary.
Document 12: Switzerland: By 1200, the Swiss plateau comprised the dominions of the houses of Savoy, Zähringer, Habsburg, and Kyburg. Some regions (Uri, Schwyz, Unterwalden, later known as Waldstätten) were accorded the Imperial immediacy to grant the empire direct control over the mountain passes. With the extinction of its male line in 1263 the Kyburg dynasty fell in AD 1264; then the Habsburgs under King Rudolph I (Holy Roman Emperor in 1273) laid claim to the Kyburg lands and annexed them extending their territory to the eastern Swiss plateau.
Document 13: Karolína Grohová: Grohová competed at the 2014 Winter Olympics for the Czech Republic. She placed 38th in the qualifying round in the sprint, failing to advance to the knockout stages. She also competed with Eva Vrabcová-Nývltová, Petra Nováková and Klára Moravcová in the relay, finishing 10th.
Document 14: Switzerland: Switzerland lies between latitudes 45° and 48° N, and longitudes 5° and 11° E. It contains three basic topographical areas: the Swiss Alps to the south, the Swiss Plateau or Central Plateau, and the Jura mountains on the west. The Alps are a high mountain range running across the central-south of the country, comprising about 60% of the country's total area. The majority of the Swiss population live in the Swiss Plateau. Among the high valleys of the Swiss Alps many glaciers are found, totalling an area of 1,063 square kilometres (410 sq mi). From these originate the headwaters of several major rivers, such as the Rhine, Inn, Ticino and Rhône, which flow in the four cardinal directions into the whole of Europe. The hydrographic network includes several of the largest bodies of freshwater in Central and Western Europe, among which are included Lake Geneva (also called le Lac Léman in French), Lake Constance (known as Bodensee in German) and Lake Maggiore. Switzerland has more than 1500 lakes, and contains 6% of Europe's stock of fresh water. Lakes and glaciers cover about 6% of the national territory. The largest lake is Lake Geneva, in western Switzerland shared with France. The Rhône is both the main source and outflow of Lake Geneva. Lake Constance is the second largest Swiss lake and, like the Lake Geneva, an intermediate step by the Rhine at the border to Austria and Germany. While the Rhône flows into the Mediterranean Sea at the French Camarque region and the Rhine flows into the North Sea at Rotterdam in the Netherlands, about 1000 km apart, both springs are only about 22 km apart from each other in the Swiss Alps.
Document 15: Margraviate of Austria: The Margraviate of Austria was a southeastern frontier march of the Holy Roman Empire created in 976 out of the territory on the border with the Principality of Hungary. Originally under the overlordship of the Dukes of Bavaria, it was ruled by margraves of the Franconian Babenberg dynasty. It became an Imperial State in its own right, when the Babenbergs were elevated to Dukes of Austria in 1156.
