<P0-S0> The monarchs of Prussia were members of the House of Hohenzollern who were the hereditary rulers of the former German state of Prussia from its founding in 1525 as the Duchy of Prussia. <P0-S1>  The Duchy had evolved out of the Teutonic Order, a Roman Catholic crusader state and theocracy located along the eastern coast of the Baltic Sea. <P0-S2>  The Teutonic Knights were under the leadership of a Grand Master, the last of whom, Albert, converted to Protestantism and secularized the lands, which then became the Duchy of Prussia. <P0-S3>  The Duchy was initially a vassal of the Kingdom of Poland, as a result of the terms of the Prussian Homage whereby Albert was granted the Duchy as part of the terms of peace following the Prussian War. <P0-S4>  When the main line of Prussian Hohenzollerns died out in 1618, the Duchy passed to a different branch of the family, who also reigned as Electors of Brandenburg in the Holy Roman Empire. <P0-S5>  While still nominally two different territories, Prussia under the suzerainty of Poland and Brandenburg under the suzerainty of the Holy Roman Empire, the two states are known together historiographically as Brandenburg-Prussia. <P0-S6>  Following the Second Northern War, a series of treaties freed the Duchy of Prussia from any vassalage to any other state, making it a fully sovereign Duchy in its own right. <P0-S7>  This complex situation (where the Hohenzollern ruler of the independent Duchy of Prussia was also a subject of the Holy Roman Emperor as Elector of Brandenburg) laid the eventual groundwork for the establishment of the Kingdom of Prussia in 1701. <P0-S8>  For diplomatic reasons, the rulers of the state were known as the King in Prussia from 1701 to 1772; largely because they still owed fealty to the Emperor as Electors of Brandenburg, the "King in Prussia" title (as opposed to "King of Prussia") avoided offending the Emperor. <P0-S9>  As the Prussian state grew through several wars and diplomatic moves throughout the 18th century, it became apparent that Prussia had become a Great Power that did not need to submit meekly to the Holy Roman Empire. <P0-S10>  By 1772, the pretense was dropped, and the style "King of Prussia" was adopted. <P0-S11>  Thus it remained until 1871, when in the aftermath of the Franco-Prussian War, the King of Prussia Wilhelm I was crowned German Emperor. <P0-S12>  From that point forward, though the Kingdom of Prussia retained its status as a constituent state of the German Empire, all remaining Kings of Prussia also served as German Emperor, and that title took precedence. <SEP> <P1-S0>  The battle was fought by the Habsburg Monarchy, the Polish–Lithuanian Commonwealth and the Holy Roman Empire, under the command of King John III Sobieski against the Ottomans and their vassal and tributary states. <P1-S1>  The battle marked the first time the Commonwealth and the Holy Roman Empire had cooperated militarily against the Ottomans, and it is often seen as a turning point in history, after which "the Ottoman Turks ceased to be a menace to the Christian world". <P1-S2> The Battle of Vienna (German: "Schlacht am Kahlen Berge" or "Kahlenberg"; Polish: "bitwa pod Wiedniem" or "odsiecz wiedeńska" (The Relief of Vienna); Modern Turkish: "İkinci Viyana Kuşatması", Ottoman Turkish: "Beç Ḳalʿası Muḥāṣarası") took place at Kahlenberg Mountain near Vienna on 1683 after the imperial city had been besieged by the Ottoman Empire for two months. <P1-S3>  In the ensuing war that lasted until 1699, the Ottomans lost almost all of Hungary to the Holy Roman Emperor Leopold I. <SEP> <P2-S0> The Magnate conspiracy, also known as the Zriny Frangipani Conspiracy (Croatian: "Zrinsko-frankopanska urota" ) in Croatia, and Wesselényi conspiracy (Hungarian: "Wesselényi-összeesküvés" ) in Hungary, was a 17th-century attempt to throw off Habsburg and other foreign influences over Hungary and Croatia. <P2-S1>  The attempted coup was caused by the unpopular Peace of Vasvár, struck in 1664 between Holy Roman Emperor Leopold I and the Ottoman Empire. <P2-S2>  The poorly organized attempt at revolt gave the Habsburgs reason to clamp down on their opponents. <P2-S3>  It was named after Hungarian Count Ferenc Wesselényi, and by Croatian counts Nikola Zrinski, Petar Zrinski and Fran Krsto Frankopan. <SEP> <P3-S0>  The second son of Ferdinand III, Holy Roman Emperor, by his first wife, Maria Anna of Spain, Leopold became heir apparent in 1654 by the death of his elder brother Ferdinand IV. <P3-S1>  Elected in 1658, Leopold ruled the Holy Roman Empire until his death in 1705. <P3-S2> Leopold I (name in full: "Leopold Ignaz Joseph Balthasar Felician"; Hungarian: "I. Lipót" ; 9 June 1640 – 5 May 1705) was Holy Roman Emperor, King of Hungary, Croatia, and Bohemia.
