Question: What was the pre-1701 capital of the country that signed the Treaty of Töplitz with Russia and Austria?

Context paragraphs:
Treaty of Zürich: The Treaty of Zurich was signed by the Austrian Empire, the French Empire, and the Kingdom of Sardinia on November 10, 1859.  The agreement was a reaffirmation of the terms of the preliminary peace of Villafranca, which brought the Austro-Sardinian War to an official close.  The treaty actually consisted of three separate treaties - a treaty between France and Austria, which reaffirmed the terms of the preliminary peace, re-established peace between the two emperors, and ceded Lombardy to France.  A second treaty, between France and Sardinia, saw France cede Lombardy to Sardinia.  The third treaty, signed by all three powers, re-established a state of peace between Austria and Sardinia.

Treaty of Paris (1810): The Treaty of Paris, signed on 6 January 1810, ended the war between France and Sweden after Sweden's defeat by Russia, an ally of France, in the Finnish War of 1808-1809.  Russia had previously been an ally of Sweden in the Third and Fourth Coalitions against France, but after Russia's defeat at Friedland, she joined France and attacked Sweden so as to compel her to join Napoleon's Continental System.  Indeed, the primary result of the treaty was Sweden's agreement to join the Continental System, so that Sweden would not trade with the UK.  Shortly after the treaty was signed, on 21 August 1810, one of Napoleon's marshals, Jean-Baptiste Bernadotte, was elected crown prince of Sweden, and he went on to found the House of Bernadotte, which remains the Royal House of Sweden.  The peace resulting from the treaty lasted until Napoleon's refusal to permit Sweden to annex Norway, which was then under the sovereignty of Denmark, an ally of France.  This was followed in January 1812 by French occupation of Swedish Pomerania for violation of the Continental System, since Sweden was still trading with the UK, and, in April, Sweden's conclusion of the Treaty of Petersburg with Russia against France.

Treaties of Reichenbach (1813): The Treaties of Reichenbach were a series of agreements signed in Reichenbach (present-day Dzierżoniów) between Great Britain, Prussia, Russia, and Austria.  These accords served to establish and strengthen a united coalition force against Napoleon I of France.  On 14 June 1813 the Treaty of Reichenbach was signed between Great Britain and Prussia.  Based on the terms of the accord, Britain agreed to provide Prussia a subsidy of 666,666 pounds sterling in order for Prussia to maintain its force of 80,000 troops.  In exchange for this aid, the king of Prussia agreed to cede the principality of Hildesheim and other territories to the Electorate of Hanover.  On 15 June 1813 the Treaty of Reichenbach was signed between Great Britain and Russia.  Based on the terms of the accord, Great Britain agreed to provide Russia with a subsidy of 1,333,334 pounds sterling in order for Russia to maintain its force of 160,000 troops.  On 27 June 1813 the Treaty of Reichenbach (also known as the "Reichenbach Convention") was signed between Prussia, Russia, and Austria.  Based on the terms of the accord, Austria agreed to declare war against Napoleon if he rejected its conditions of peace.

Prussia: Prussia (German:    ) was a prominent historical German state originating out of the Duchy of Prussia and the Margraviate of Brandenburg, and centred on the region of Prussia.  For centuries, the House of Hohenzollern ruled Prussia, successfully expanding its size by way of an unusually well-organised and effective army.  Prussia, with its capital in Königsberg and from 1701 in Berlin, shaped the history of Germany.

Treaty of Brest-Litovsk: The Treaty of Brest-Litovsk was a peace treaty signed on 3 March 1918 between the new Bolshevik government of Soviet Russia and the Central Powers (Germany, Austria-Hungary, Bulgaria, and the Ottoman Empire), that ended Russia's participation in World War I.  The treaty was signed at Brest-Litovsk (Polish: "Brześć Litewski" ; since 1945 Brest), after two months of negotiations.  The treaty was agreed upon by the Bolshevik government under threat of further advances by German and Austrian forces.  According to the treaty, Soviet Russia defaulted on all of Imperial Russia's commitments to the Triple Entente alliance.

Treaty of Värälä: The Treaty of Värälä (sometimes known as the Treaty of Wereloe) was a treaty signed in Värälä, Elimäki Municipality, Finland, between Russia (represented by Otto Heinrich Igelström) and Sweden (represented by Gustaf Mauritz Armfelt).  It was signed on 14 August 1790 and concluded the Russo-Swedish War.  The treaty confirmed status quo ante bellum with respect to the borders, however Russia's right to interfere with Swedish interior affairs from the Treaty of Nystad was expressly revoked.  The provisions of the previous Treaty of Abo were basically confirmed.

Treaty of Töplitz: The Treaty of Töplitz (other spellings: Treaty of Toeplitz, Treaty of Toplitz) was signed in Töplitz on 9 September 1813, between Russia, Austria, and Prussia.  The purpose of the agreement was to establish and strengthen a united coalition force against Napoleon I of France.  Based on the terms of the accord, all signatories agreed to support each other with 60,000 troops.  Another Treaty of Töplitz was signed between Great Britain and Austria.

Russo-Persian Treaty of Friendship (1921): The Russo-Persian Treaty of Friendship was signed on February 26, 1921 between representatives of Iran and the Soviet Russia.  Based on the terms of the treaty, all previous agreements made between the signatories including the Treaty of Turkmenchay were canceled.  Moreover, both the Soviet Russia and Iran were given full and equal shipping rights in the Caspian Sea along with the right to fly their respective national flags on their commercial vessels.  Ratifications were exchanged in Teheran on February 26, 1922.  It was registered in "League of Nations Treaty Series" on June 7, 1922.  The original purpose of the treaty was to prevent White Russian counter-revolutionary forces who fled to Iran after the Bolshevik Revolution from attacking the Soviets from Iranian territory as had happened as late as 1918.  The passage of the treaty, and particularly articles 5 and 6, was subject to vigorous debate in the Persian parliament; anti-British sentiment, however, lead to its acceptance without alteration.  The treaty would serve as the basis for a Soviet occupation in 1941, and articles 5 and 6 were eventually repudiated by Iran in 1979.

Treaty of Hubertusburg: The Treaty of Hubertusburg (German: "Frieden von Hubertusburg" ) was signed on 15 February 1763 at Hubertusburg Castle by Prussia, Austria and Saxony to end the Third Silesian War.  Together with the Treaty of Paris, signed five days earlier, it marked the end of the Seven Years' War.  The treaty ended the continental conflict with no significant changes in prewar borders.  Austria and Saxony renounced all claims to the Silesian territories ceded to Prussia in the 1742 Treaty of Berlin and the 1745 Treaty of Dresden.  Prussia clearly stood among the ranks of the European great powers, while the treaty enhanced the rivalry with Austria.

Treaty of Adrianople (1829): The Treaty of Adrianople (also called the Treaty of Edirne) concluded the Russo-Turkish War of 1828–29, between Russia and the Ottoman Empire.  It was signed on 14 September 1829 in Adrianople by Count Alexey Fyodorovich Orlov of Russia and by of the Ottoman Empire.  The Ottoman Empire gave Russia access to the mouths of the Danube and the fortresses of Akhaltsikhe and Akhalkalaki in Georgia.  The Sultan recognized Russia's possession of Georgia (with Imeretia, Mingrelia, Guria) and of the Khanates of Erivan and Nakhichevan which had been ceded to the tsar by Persia in the Treaty of Turkmenchay a year earlier.  The treaty opened the Dardanelles to all commercial vessels, thus liberating commerce for cereals, livestock and wood.  However, it took the Treaty of Hünkâr İskelesi (1833) to finally settle the Straits Question between the signatories.
