Question: What country does Louis de Silvestre and Augustus II the Strong have in common?

Context paragraphs:
Pacification Sejm (1736): The Pacification Sejm was a session of the Sejm in 1736 that concluded the War of the Polish Succession in the Polish-Lithuanian Commonwealth that erupted after the death of Augustus II the Strong in February 1733.  It confirmed the accession of Augustus III to the Polish throne, and gave Augustus the power to appoint as Duke of Courland a candidate who had the approval of Russia, Prussia, and the local nobility.  (This power was in effect a retroactive approval of Augustus' agreement with Anna of Russia that she could name her preferred candidate, Ernst Johann von Biron, to that post.)

Civil war in Poland (1704–06): The civil war in Poland (1704–1706) was a part of a larger European conflict, the Great Northern War.  It focused on the struggle for the Polish throne between King Stanisław I supported by his Warsaw Confederation and Sweden, and the Russian-backed Sandomierz Confederation of Augustus II the Strong.  The war ended with Stanisław's victory and the Treaty of Altranstädt in 1706 in which August II renounced his claims to the Polish throne.  Stanisław's triumph would be short-lived, however, as by 1709 he would be forced to give up the throne to Augustus II once again.

Marie-Maximilienne de Silvestre: Marie-Maximilienne de Silvestre (1708–1798) was a French painter.

Augustus II the Strong: Augustus II the Strong (German: "August II.  der Starke" ; Polish: "August II Mocny" ; Lithuanian: "Augustas II" ; 12 May 1670 – 1 February 1733) of the Albertine line of the House of Wettin was Elector of Saxony (as Frederick Augustus I), Imperial Vicar and elected King of Poland and Grand Duke of Lithuania.

Crown of Augustus II the Strong: The Crown of Augustus II was intended for his coronation as a King of Poland.  The crown was made in 1697 by Freiburg's goldsmith Johann Friedrich Klemm.  It was not used, however.  The Augustus II's crown is kept in Dresden Armory (Rüstkammer) in Dresden, Germany.

Louis de Silvestre: Louis de Silvestre (23 June 1675 – 11 April 1760) was a French portrait and history painter.  He was court painter to King Augustus II of Poland, and director of the Royal Academy of Arts in Dresden.

Augustus Bridge: The Augustus Bridge is a bridge in the city of Dresden, in the state Saxony in Germany.  It was built between 1907 and 1910.  Crossing the river Elbe, the road bridge connects the Innere Neustadt in the north (right bank) with the historic area of the city in the south (left bank).  There has been a bridge at the same location since at least the 12th century.  Under king Augustus II the Strong of Poland and Saxony, a new sandstone bridge was built between 1727 and 1731.  This bridge was replaced by the present, also sandstone, bridge with 9 arches in order to provide a wider opening for river traffic.  It was designed by Wilhelm Kreis and Theodor Klette.  Three tram lines of the Dresdner Verkehrsbetriebe pass over the Augustus Bridge.

Johann Patkul: Johann Reinhold Patkul (27 July 1660 – 10 October 1707) was a Livonian nobleman, politician and agitator of Baltic German extraction.  Born as a subject to the Swedish Crown, he protested against the manner of King Charles XI of Sweden's reduction in Livonia, enraging the king, who had him arrested and sentenced to mutilation and death (1694).  Patkul fled from the Swedish Empire to continental Europe, and played a key role in the secret diplomacy (1698-1699) allying Peter I of Russia, Augustus II the Strong of Saxony and the Poland–Lithuania - as well as Christian V and his successor Frederick IV of Denmark–Norway - against Charles XII of Sweden, triggering the Great Northern War of 1700-1721.  During the first war years, Patkul retained a key role in the communication between the allies and other European courts, holding positions at king Augustus's court first in Augustus's interests (1698-1700), then in tsar Peter's service (1702- ).  In late 1705 Patkul fell from Augustus's favor and was arrested and charged with high treason.  Throughout the following year he was detained first in Sonnenstein, then in Königstein (both in Saxony), before Charles XII forced Augustus to extradite him by the Treaty of Altranstädt in late 1706.  Patkul spent another year in Swedish detention before Charles XII had him broken on the wheel and decapitated.

Polish–Lithuanian royal election, 1704: In early 1700, King of Poland, Grand Duke of Lithuania and Elector of Saxony, Augustus II the Strong began the Great Northern War by attacking Swedish Livonia.  Despite Russian support, Saxon army lost several battles, and soon afterwards, forces of the Swedish Empire controlled most of the Polish-Lithuanian Commonwealth.  In June 1703, Augustus II convened the Extraordinary Sejm in Lublin, where he faced widespread criticism.  His opponent were led by Primate of Poland, Michał Radziejowski, and sons of late King Jan III Sobieski, Jakub and Konstanty.

Great Northern War: The Great Northern War (1700–21) was a conflict in which a coalition led by the Tsardom of Russia successfully contested the supremacy of the Swedish Empire in Central, Northern, and Eastern Europe.  The initial leaders of the anti-Swedish alliance were Peter I of Russia, Frederick IV of Denmark–Norway and Augustus II the Strong of Saxony-Poland.  Frederick IV and Augustus II were defeated by Sweden, under Charles XII, and forced out of the alliance in 1700 and 1706 respectively, but rejoined it in 1709 after the defeat of Charles XII at the Battle of Poltava.  George I of Great Britain and of Brunswick-Lüneburg (Hanover) joined the coalition in 1714 for Hanover and in 1717 for Britain, and Frederick William I of Brandenburg-Prussia joined it in 1715.
