Margraviate of Baden in the context of "Margraviate of Baden-Baden"

The Grand Duchy of Baden (German: Großherzogtum Baden) was a German polity on the east bank of the Rhine. It originally existed as a sovereign state from 1806 to 1871 and later as part of the German Empire until 1918.

The duchy's 12th-century origins were as a margraviate that eventually split into two, Baden-Durlach and Baden-Baden, before being reunified in 1771. The territory grew and assumed its ducal status after the dissolution of the Holy Roman Empire but suffered a revolution in 1848, whose demands had been formulated in Offenburg the previous year at a meeting now considered the first-ever democratic program in Germany. With the collapse of the German Empire it became part of the Weimar Republic under the name Republic of Baden.

Karlsruhe (/ˈkɑːrlzruːə/ KARLZ-roo-ə; US also /ˈkɑːrls-/ KARLSS-; German: [ˈkaʁlsˌʁuːə] ; South Franconian: Kallsruh) is the third-largest city of the German state of Baden-Württemberg, after its capital Stuttgart and Mannheim, and the 22nd-largest city in the nation, with 308,436 inhabitants. It is also a former capital of Baden, a historic region named after Hohenbaden Castle in the city of Baden-Baden. Located on the right bank of the Rhine (Upper Rhine) near the French border, between the Mannheim-Ludwigshafen conurbation to the north and Strasbourg to the south, Karlsruhe is Germany's legal center, being home to the Federal Constitutional Court, the Federal Court of Justice and the Public Prosecutor General.

Karlsruhe was the capital of the Margraviate of Baden-Durlach (Durlach: 1565–1718; Karlsruhe: 1718–1771), the Margraviate of Baden (1771–1803), the Electorate of Baden (1803–1806), the Grand Duchy of Baden (1806–1918), and the Republic of Baden (1918–1945). Its most remarkable building is Karlsruhe Palace, which was built in 1715. It contains the Baden State Museum, the large cultural, art and regional history museum of the Baden region of Baden-Württemberg. There are nine institutions of higher education in the city, most notably the Karlsruhe Institute of Technology. Karlsruhe/Baden-Baden Airport is the second-busiest airport in Baden-Württemberg after Stuttgart Airport, and the 17th-busiest airport in Germany.

The Treaty of Rastatt was a peace treaty between France and Austria that was concluded on 7 March 1714 in the Baden city of Rastatt to end the War of the Spanish Succession between both countries. The treaty followed the Treaty of Utrecht of 11 April 1713, which had ended hostilities between France and Spain, on the one hand, and Great Britain and the Dutch Republic, on the other. A third treaty at Baden, Switzerland, was required to end the hostilities between France and the Holy Roman Empire.

By 1713, all parties to the war had been militarily depleted, and it was unlikely that continuing the conflict would bring about any results in the foreseeable future. The First Congress of Rastatt opened in November 1713 between France and Austria. The negotiations culminated in the Treaty of Rastatt on 7 March 1714, which ended hostilities and complemented the Treaty of Utrecht, which had been signed the previous year.

The Second Congress of Rastatt, which began its deliberations in November 1797, was intended to negotiate a general peace between the French Republic and the Holy Roman Empire, and to draw up a compensation plan to compensate those princes whose lands on the left bank of the Rhine had been seized by France in the War of the First Coalition. Facing the French delegation was a 10-member Imperial delegation made up of delegates from the electorates of Mainz, Saxony, Bavaria, Hanover, as well as the secular territories of Austria, Baden, Hesse-Darmstadt, the Prince-Bishopric of Würzburg, and the imperial cities of Augsburg and Frankfurt. The congress was interrupted when Austria and Russia resumed war against France in March 1799 at the start of the War of the Second Coalition, thus rendering the proceedings moot. Furthermore, as the French delegates attempted to return home, they were attacked by Austrian cavalrymen or possibly French royalists masquerading as such. Two diplomats were killed and a third seriously injured. The congress was held at Rastatt near Karlsruhe.

The Margraviate of Baden-Durlach was an early modern territory of the Holy Roman Empire, in the upper Rhine valley, which existed from 1535 to 1771. It was formed when the Margraviate of Baden was split between the sons of Margrave Christopher I and was named for its capital, Durlach. The other half of the territory became the Margraviate of Baden-Baden, located between the two halves of Baden-Durlach. Baden-Durlach became Lutheran during the Protestant Reformation, unlike Baden-Baden, which remained Catholic. Baden-Durlach occupied Baden-Baden from 1594 to 1622, but was driven out after being defeated at the Battle of Wimpfen, during the Thirty Years' War (1618–1648). The territory was ravaged during the Nine Years' War (1688–1697). Following the extinction of the Baden-Baden line in 1771, the Baden-Durlach inherited their territories and reunited the Margraviate of Baden. The reunified territory was caught up in the French Revolutionary and Napoleonic Wars, emerging in 1806 as the Grand Duchy of Baden.

Hohenbaden Castle (at the time of its establishment Schloss Hohenbaden, now Old castle or Altes Schloss) in German Baden-Baden was the residence of the margraves of Baden for almost 400 years. The castle was built around 1100 by Herman II, Margrave of Baden (1074–1130) on the west flank of the Battert rock.

Under Margrave Bernard I (1372–1431) the Gothic lower castle was built. This was expanded again by Jacob, Margrave from 1431 to 1453. At its peak, the castle had a hundred rooms. Christopher I built the New castle in the town of Baden itself and moved there in 1479.

Karl Wenzeslaus Rodecker von Rotteck (18 July 1775, Freiburg, Margraviate of Baden – 26 November 1840, Freiburg, Grand Duchy of Baden) was a German political activist, historian, politician and political scientist. He was a prominent advocate of freedom of the press and the abolition of compulsory labor.
