Augustus III of Poland in the context of "Hubertusburg"

Johann Sebastian Bach (31 March [O.S. 21 March] 1685 – 28 July 1750) was a German composer and musician of the late Baroque period. He is known for his prolific output across a variety of instruments and forms, including the orchestral Brandenburg Concertos; solo instrumental works such as the cello suites and sonatas and partitas for solo violin; keyboard works such as the Goldberg Variations and The Well-Tempered Clavier; organ works such as the Schübler Chorales and the Toccata and Fugue in D minor; and choral works such as the St Matthew Passion and the Mass in B minor. Since the 19th-century Bach Revival, he has been widely regarded as one of the greatest composers in the history of Western music.

The Bach family had already produced several composers when Johann Sebastian was born as the last child of a city musician, Johann Ambrosius, in Eisenach. After being orphaned at age 10, he lived for five years with his eldest brother, Johann Christoph, then continued his musical education in Lüneburg. In 1703 he returned to Thuringia, working as a musician for Protestant churches in Arnstadt and Mühlhausen. Around that time he also visited for longer periods the courts in Weimar, where he expanded his organ repertory, and the reformed court at Köthen, where he was mostly engaged with chamber music. By 1723 he was hired as Thomaskantor (cantor with related duties at St Thomas School) in Leipzig. There he composed music for the principal Lutheran churches of the city and Leipzig University's student ensemble, Collegium Musicum. In 1726 he began publishing his organ and other keyboard music. In Leipzig, as had happened during some of his earlier positions, he had difficult relations with his employer. This situation was somewhat remedied when his sovereign, Augustus III of Poland, granted him the title of court composer of the Elector of Saxony in 1736. In the last decades of his life, Bach reworked and extended many of his earlier compositions. He died due to complications following eye surgery in 1750 at the age of 65. Four of his twenty children, Wilhelm Friedemann, Carl Philipp Emanuel, Johann Christoph Friedrich, and Johann Christian, became composers.

The szlachta (Polish pronunciation: [ˈʂlaxta] ; Lithuanian: šlėkta; lit. 'nobility') , the nobles, were the noble estate of the realm in the Kingdom of Poland, the Grand Duchy of Lithuania, and the Polish–Lithuanian Commonwealth. It was the dominating social class in the Kingdom of Poland and the Polish-Lithuanian Commonwealth, which was exercising political rights and power. Szlachta as a class differed substantially from the feudal nobility of Western Europe. The estate was officially abolished in 1921 by the March Constitution.

The origins of the szlachta are obscure and the subject of several theories. The szlachta secured substantial and increasing political power and rights throughout its history, beginning with the reign of King Casimir III the Great between 1333 and 1370 in the Kingdom of Poland until the decline and end of the Polish–Lithuanian Commonwealth in the late 18th century. Apart from providing officers for the army, its chief civic obligations included electing the monarch and filling honorary and advisory roles at court that would later evolve into the upper legislative chamber, the Senate. The szlachta electorate also took part in the government of the Commonwealth via the lower legislative chamber of the Sejm (bicameral national parliament), composed of representatives elected at local sejmiks (local szlachta assemblies). Sejmiks performed various governmental functions at local levels, such as appointing officials and overseeing judicial and financial governance, including tax-raising. The szlachta assumed various governing positions, including voivode, marshal of voivodeship, castellan, and starosta.

Charles III (Spanish: Carlos Sebastián de Borbón y Farnesio; 20 January 1716 – 14 December 1788) was King of Spain from 1759 until his death in 1788. He was also Duke of Parma and Piacenza as Charles I (1731–1735), King of Naples as Charles VII and King of Sicily as Charles III (or V) (1735–1759). He was the fourth son of Philip V of Spain and the eldest son of Philip's second wife, Elisabeth Farnese. During his reign, Charles was a proponent of enlightened absolutism and regalism in Europe.

In 1731, the 15-year-old Charles became Duke of Parma and Piacenza following the death of his childless grand-uncle Antonio Farnese. In 1734, at the age of 18, he led Spanish troops in a bold and almost entirely bloodless march down Italy to seize the Kingdom of Naples and Kingdom of Sicily and enforce the Spanish claim to their thrones. In 1738, he married the Princess Maria Amalia of Saxony, daughter of Augustus III of Poland, who was an educated, cultured woman. The couple had 13 children, eight of whom reached adulthood. They resided in Naples for 19 years. Charles gained valuable experience in his 25-year rule in Italy, so that he was well prepared as the monarch of the Spanish Empire. His policies in Italy prefigured ones he would put in place in his 30-year rule of Spain.

The War of the Polish Succession (Polish: Wojna o sukcesję polską; 1733–35) was a major European conflict sparked by a civil war in the Polish–Lithuanian Commonwealth over the succession to Augustus II the Strong, which the other European powers widened in pursuit of their own national interests. France and Spain, the two Bourbon powers, tested the power of the Austrian Habsburgs in Western Europe, as did the Kingdom of Prussia, whilst Saxony and Russia mobilized to support the eventual victor. The fighting in Poland–Lithuania resulted in the accession of Augustus III, who in addition to Russia and Saxony, was politically supported by the Habsburgs.

The war's major military campaigns and battles occurred outside the borders of Poland–Lithuania. The Bourbons, supported by Charles Emmanuel III of Sardinia, moved against isolated Habsburg territories. In the Rhineland, France successfully took the Duchy of Lorraine, and in Italy, Spain regained control over the kingdoms of Naples and Sicily lost in the War of the Spanish Succession, while territorial gains in northern Italy were limited despite bloody campaigning. Great Britain's unwillingness to support Habsburg Austria demonstrated the infirmity of the Anglo-Austrian Alliance.

Stanisław II August (born Stanisław Antoni Poniatowski; 17 January 1732 – 12 February 1798), known also by his regnal Latin name Stanislaus II Augustus, and as Stanisław August Poniatowski (Lithuanian: Stanislovas Augustas Poniatovskis), was King of Poland and Grand Duke of Lithuania from 1764 to 1795, and the last monarch of the Polish–Lithuanian Commonwealth.

Born into wealthy Polish aristocracy, Poniatowski arrived as a diplomat at the Russian imperial court in Saint Petersburg in 1755 at the age of 22 and became intimately involved with the future empress Catherine the Great. With her aid, he was elected King of Poland and Grand Duke of Lithuania by the Sejm in September 1764 following the death of Augustus III. Contrary to expectations, Poniatowski attempted to reform and strengthen the large but ailing Commonwealth. His efforts were met with external opposition from neighbouring Prussia, Russia and Austria, all committed to keeping the Commonwealth weak. From within he was opposed by conservative interests, which saw the reforms as a threat to their traditional liberties and privileges granted centuries earlier.

The only surviving original piece of the Polish crown jewels (Polish: Polskie klejnoty koronne) from the time of the Piast dynasty is the ceremonial sword Szczerbiec. It is currently on display along with other preserved royal items at the Wawel Royal Castle Museum in Kraków.

Several royal crowns were made, including several during the 16th century, a "Hungarian Crown", a "Swedish Crown" used by the Vasa kings, and others that were subsequently lost or destroyed. The crown regalia used by the Saxon kings, and some remainders of older Polish monarchs which were appropriated by king Augustus II, also the Elector of Saxony — like a cup of Queen Jadwiga so-called roztruchan, and the magnificent scale armour, so-called karacena, of King John III Sobieski — are today on display in the Grünes Gewölbe and the Rüstkammer in Dresden, Germany.
