War of the Austrian Succession in the context of "First Silesian War"

The Seven Years' War, 1756 to 1763, was a global war fought by numerous great powers, primarily in Europe, with significant subsidiary campaigns in North America and South Asia. The warring states were Great Britain and Prussia fighting against France and Austria, with other countries joining these coalitions: Portugal, Spain, Saxony, Sweden, and Russia. Related conflicts include the Third Silesian War, French and Indian War, Third Carnatic War, Anglo-Spanish War (1762–1763), and Spanish–Portuguese War.

Although the War of the Austrian Succession ended with the Treaty of Aix-la-Chapelle (1748), none of the signatories were happy with the terms, and it was generally viewed as a temporary armistice. It led to a strategic realignment known as the Diplomatic Revolution that ended the long-running rivalry between Austria and France. The two declared war on Britain after signing the Treaty of Versailles (1756), with a second agreement in 1757 bringing Prussia into the war.

The War of Jenkins' Ear was fought between Great Britain and Spain from 1739 to 1748. Most of the fighting took place in New Granada and the Caribbean Sea, with major operations over by 1742. It is considered a related conflict of the 1740 to 1748 War of the Austrian Succession.

The name derives from Robert Jenkins, a British sea captain whose ear was allegedly severed in April 1731 by Spanish coast guards searching his ship for contraband. In 1738, opposition politicians in the British Parliament used the incident to incite support for a war against Spain.

Charles VI (German: Karl; Latin: Carolus; 1 October 1685 – 20 October 1740) was Holy Roman Emperor and ruler of the Austrian Habsburg monarchy from 1711 until his death, succeeding his elder brother, Joseph I. He unsuccessfully claimed the throne of Spain following the death of his relative, Charles II. In 1708, he married Elisabeth Christine of Brunswick-Wolfenbüttel, by whom he had his four children: Leopold Johann (who died in infancy), Maria Theresa, Maria Anna (Governess of the Austrian Netherlands), and Maria Amalia (who also died in infancy).

Four years before the birth of Maria Theresa, faced with his lack of male heirs, Charles provided for a male-line succession failure with the Pragmatic Sanction of 1713. The Emperor favoured his own daughters over those of his elder brother and predecessor, Joseph I, in the succession, ignoring the Mutual Pact of Succession he had signed during the reign of his father, Leopold I. Charles sought the other European powers' approval. They demanded significant terms, among which were that Austria close the Ostend Company. In total, the states of Great Britain, France, Saxony-Poland, the Dutch Republic, Spain, Venice, the Papal States, Prussia, Russia, Denmark, Savoy-Sardinia, and Bavaria, plus the Diet of the Holy Roman Empire, recognised the sanction. France, Spain, Saxony-Poland, Bavaria, and Prussia later reneged. Charles died in 1740, sparking the War of the Austrian Succession, which plagued his successor, Maria Theresa, for eight years.

The term French–Habsburg rivalry (French: Rivalité franco-habsbourgeoise; German: Habsburgisch-französischer Gegensatz) describes the rivalry between France and the House of Habsburg. The Habsburgs headed an expansive and evolving empire that included, at various times, the Holy Roman Empire, the Spanish Empire, Portugal through Iberian Union, Austria, Bohemia and Hungary from the Diet of Augsburg in the High Middle Ages until the dissolution of the monarchy following World War I in the late modern period.

In addition to holding the Austrian hereditary lands, the Habsburg dynasty ruled the Low Countries (1482–1794), Spain (1504–1700) and the Holy Roman Empire (1438–1806). All these lands were in personal union under Emperor Charles V. The expansion of the Habsburgs into western Europe increasingly led to border tensions with the Kingdom of France, which found itself encircled by Habsburg territory. The subsequent rivalry between the two powers became a cause for several conflicts. These include parts of the Anglo-French Wars (1066–1815), the War of the Burgundian Succession (1477–1482), the Italian Wars (1494–1559), the Thirty Years' War (1618–1648), the Nine Years' War (1688–1697), and the succession wars of Jülich (1609–1614), Mantua (1628–1631), Spain (1700–1713), Poland (1733–1736) and Austria (1740–1748).

The Russo-Swedish War of 1741–1743 (also known as The War of the Hats) was instigated by the Hats, a Swedish political party that aspired to regain the territories lost to Russia during the Great Northern War, and by French diplomacy, which sought to divert Russia's attention from supporting its long-standing ally the Habsburg monarchy in the War of the Austrian Succession. The war was a disaster for Sweden, which lost more territory to Russia.

The House of Kleist is the name of an old and distinguished Prussian noble family, originating in Pomerania, whose members obtained many important military and administrative positions within the Kingdom of Prussia and later in the German Empire. Members of the family served as officers in Prussian and German conflicts including the War of Spanish Succession, War of the Austrian Succession, Seven Years' War, Napoleonic Wars, World War I and World War II.

The poet and author Heinrich von Kleist is the most famous member of the family.

Maria Theresa (Maria Theresia Walburga Amalia Christina; 13 May 1717 – 29 November 1780) was the ruler of the Habsburg monarchy from 1740 until her death in 1780, and the only woman to hold the position in her own right. She was the sovereign of Austria, Hungary, Croatia, Bohemia, Transylvania, Slavonia, Mantua, Milan, Moravia, Galicia and Lodomeria, Dalmatia, Austrian Netherlands, Carinthia, Carniola, Gorizia and Gradisca, Austrian Silesia, Tyrol, Styria and Parma. By marriage, she was Duchess of Lorraine, Grand Duchess of Tuscany, and Holy Roman Empress.

Maria Theresa started her 40-year reign when her father, Charles VI, Holy Roman Emperor, died on 20 October 1740. Charles VI paved the way for her accession with the Pragmatic Sanction of 1713 and spent his entire reign securing it through international diplomacy. He neglected the advice of Prince Eugene of Savoy, who believed that a strong military and a rich treasury were more important than mere signatures. Eventually, Charles VI left behind a weakened and impoverished state, particularly due to the War of the Polish Succession and the Russo-Turkish War (1735–1739). Moreover, upon his death, Saxony, Prussia, Bavaria, and France all repudiated the sanction they had recognised during his lifetime. Frederick II of Prussia (who became Maria Theresa's greatest rival for most of her reign) promptly invaded and took the affluent Habsburg province of Silesia in the eight-year conflict known as the War of the Austrian Succession. In defiance of the grave situation, she managed to secure the vital support of the Hungarians for the war effort. During the course of the war, Maria Theresa successfully defended her rule over most of the Habsburg monarchy, apart from the loss of Silesia and a few minor territories in Italy. Maria Theresa later unsuccessfully tried to recover Silesia during the Seven Years' War.

The House of Lorraine (German: Haus Lothringen) originated as a cadet branch of the House of Metz. It inherited the Duchy of Lorraine in 1473 after the death without a male heir of Nicholas I, Duke of Lorraine. By the marriage of Francis of Lorraine to Maria Theresa of Austria in 1736, and with the success in the ensuing War of the Austrian Succession (1740–1748), the House of Lorraine was joined to the House of Habsburg and became known as the House of Habsburg-Lorraine (German: Haus Habsburg-Lothringen). Francis, his sons Joseph II and Leopold II, and his grandson Francis II were the last four Holy Roman emperors from 1745 until the dissolution of the empire in 1806. The House of Habsburg-Lorraine inherited the Habsburg Empire, ruling the Austrian Empire and then Austria-Hungary until the dissolution of the monarchy in 1918.

Although its senior agnates are the dukes of Hohenberg, the house is currently headed by Karl von Habsburg (born 1961), grandson of the last emperor Charles I.

The Third Silesian War (German: Dritter Schlesischer Krieg) was a war between Prussia and Austria (together with its allies) that lasted from 1756 to 1763 and confirmed Prussia's control of the region of Silesia (now in south-western Poland). The war was fought mainly in Silesia, Bohemia and Upper Saxony and formed one theatre of the Seven Years' War. It was the last of three Silesian Wars fought between Frederick the Great's Prussia and Maria Theresa's Austria in the mid-18th century, all three of which ended in Prussian control of Silesia.

This conflict can be viewed as a continuation of the First and Second Silesian Wars of the previous decade. After the Treaty of Aix-la-Chapelle ended the War of the Austrian Succession, Austria enacted broad reforms and upended its traditional diplomatic policy to prepare for renewed war with Prussia. As with the previous Silesian Wars, no particular triggering event initiated the conflict; rather, Prussia struck opportunistically to disrupt its enemies' plans. The war's cost in blood and treasure was high on both sides, and it ended inconclusively when neither of the main belligerents could sustain the conflict any longer.
