Prelude (1370–1569) and the
Grand Duchy of Lithuania in 1526. The
Kingdom of Poland and the
Grand Duchy of Lithuania underwent an alternating series of wars and alliances across the 13th and 14th centuries. The relations between the two states differed at times as each strived and competed for political, economic or military dominance of the region. In turn, Poland had remained a staunch ally of its southern neighbour,
Hungary. The last Polish monarch from the native
Piast dynasty,
Casimir the Great, died on 5 November 1370 without fathering a legitimate male heir. Consequently, the crown passed onto his Hungarian nephew,
Louis of Anjou, who ruled the
Kingdom of Hungary in a
personal union with Poland. Louis died on 10 September 1382 and, like his uncle, did not produce a son to succeed him. His two daughters,
Mary and
Jadwiga (Hedwig), held claims to the vast dual realm. The future
queen regnant was betrothed to young
William Habsburg, Duke of Austria, but certain factions of the nobility remained apprehensive believing that William would not secure domestic interests. Instead, they turned to
Jogaila, the Grand Duke of Lithuania. Jogaila was a lifelong
pagan and vowed to
adopt Catholicism upon marriage by signing the
Union of Krewo on 14 August 1385. The Act imposed Christianity in Lithuania and transformed Poland into a
diarchy, a kingdom ruled over by two sovereigns; their descendants and successive monarchs held the titles of king and grand duke respectively. The ultimate clause dictated that Lithuania was to be merged in perpetuity (
perpetuo applicare) with the Polish Kingdom; however, this did not take effect until 1569. Jogaila was crowned as Władysław II Jagiełło at
Wawel Cathedral on 4 March 1386.
Union of Lublin (1569) joined the
Kingdom of Poland and the
Grand Duchy of Lithuania in 1569. Several minor agreements were struck before unification, notably the
Union of Kraków and Vilnius, the
Union of Vilnius and Radom and the
Union of Grodno. Lithuania's vulnerable position and rising tensions on its eastern flank persuaded the nobles to seek a closer bond with Poland. The idea of a federation presented better economic opportunities, whilst securing Lithuania's borders from hostile states to the north, south and east. Lesser Lithuanian nobility were eager to share the personal privileges and political liberties enjoyed by the Polish
szlachta, but did not accept Polish demands for the incorporation of the Grand Duchy into Poland as a mere province, with no sense of autonomy.
Mikołaj "the Red" Radziwiłł (Radvila Rudasis) and his cousin
Mikołaj "the Black" Radziwiłł, two prominent nobles and military commanders in Lithuania, vocally opposed the union. A fierce proponent of a single unified Commonwealth was
Sigismund II Augustus, who was childless and ailing. According to historians, it was his active involvement which hastened the process and made the union possible. A parliament (
sejm) convened on 10 January 1569 in the city of
Lublin, attended by envoys from both nations. It was agreed that the merger will take place the same year and both parliaments will be fused into a joint assembly. No independent parliamentary convocation or
diet was henceforth permitted. Whilst the military remained separate, a unified foreign policy meant that Lithuanian troops were obliged to contribute during a conflict not to their advantage. As a result, several Lithuanian
magnates deplored the accords and left the assembly in protest. Sigismund II used his authority as grand duke and enforced the Act of Union
in contumaciam. In fear, the absent nobles promptly returned to the negotiations. The
Union of Lublin was passed by the gathered deputies and signed by attendees on 1 July, thus creating the Polish–Lithuanian Commonwealth. Upon ascending the throne, Henry signed the contractual agreement known as the
Pacta conventa and approbated the
Henrician Articles. The Act stated the fundamental principles of governance and
constitutional law in the Polish–Lithuanian Commonwealth. In June 1574, Henry abandoned Poland and headed back to claim the French crown following the death of his brother and predecessor,
Charles IX. The throne was subsequently declared vacant. The interregnum concluded on 12 December 1575 when primate
Jakub Uchański declared
Maximilian II, Holy Roman Emperor, as the next king. The decision was condemned by the anti-Habsburg coalition, which demanded a "native" candidate, known as "Piasts". As a compromise, on 13 December 1575
Anna Jagiellon – sister of Sigismund Augustus and a member of the
Jagiellonian dynasty – became the new monarch. The nobles simultaneously elected
Stephen Báthory as co-regent, who ruled
jure uxoris.
Piotr Zborowski supported Bathory as he wanted to promote a princely or ducal candidate. He also endorsed the
Duke of Ferrara. Báthory, unable to penetrate the city's extensive fortifications, succumbed to the demands for greater privileges and freedoms. Most importantly, Poland gained the
Hanseatic city of
Riga on the
Baltic Sea. , who reigned between 1587 and 1632, presided over an era of prosperity and territorial expansion of the Commonwealth. In 1587,
Sigismund Vasa – the son of
John III of Sweden and
Catherine Jagiellon – won the election, but his claim was overtly contested by
Maximilian III of Austria, who launched a
military expedition to challenge the new king. His
defeat in 1588 at the hands of
Jan Zamoyski sealed Sigismund's right to the throne of Poland and Sweden. Sigismund's long reign marked an end to the
Polish Golden Age and the beginning of the Silver Age. A devout Catholic, he hoped to restore
absolutism and imposed
Roman Catholicism during the height of the
Counter-Reformation. His intolerance towards the
Protestants in Sweden sparked a
war of independence, which ended the
Polish–Swedish union. As a consequence, he was deposed in Sweden by his uncle
Charles IX Vasa. In Poland, the
Zebrzydowski rebellion was brutally suppressed. Sigismund III then initiated a policy of
expansionism, and
invaded Russia in 1609 when that country was plagued by a civil war known as the
Time of Troubles. In July 1610, the outnumbered Polish force comprising
winged hussars defeated the Russians at the
Battle of Klushino, which enabled the Poles to take and occupy
Moscow for the next two years. The disgraced
Vasili IV of Russia was transported in a cage to Warsaw where he paid a tribute to Sigismund; Vasili was later murdered in captivity. The Commonwealth forces were eventually driven out on 4 November 1612 (celebrated as
Unity Day in Russia). The war concluded with a
truce that granted Poland–Lithuania extensive territories in the east and marked its largest territorial expansion. At least five million Russians died between 1598 and 1613, the result of continuous conflict, famine and Sigismund's invasion. (parliament) of the Polish–Lithuanian Commonwealth in the early 17th century The
Polish–Ottoman War (1620–21) forced Poland to withdraw from
Moldavia in southeastern Europe, but Sigismund's victory over the Turks at
Khotyn diminished the supremacy of the Sultanate and eventually led to the murder of
Osman II. This secured the Turkish frontier for the duration of Sigismund's rule. In spite of the victories in the
Polish–Swedish War (1626–1629), the exhausted Commonwealth army signed the
Treaty of Altmark which ceded much of Livonia to Sweden under
Gustavus Adolphus. At the same time, the country's powerful
parliament was dominated by nobles (
Pic. 2) who were reluctant to get involved in the
Thirty Years' War; this neutrality spared the country from the ravages of a political-religious conflict that devastated most of contemporary Europe. During this period, Poland was experiencing a cultural awakening and extensive developments in arts and architecture; the first
Vasa king openly sponsored foreign painters, craftsmen, musicians and engineers, who settled in the Commonwealth at his request. Sigismund's eldest son,
Ladislaus succeeded him as Władysław IV in 1632 with no major opposition. A skilled tactician, he invested in
artillery, modernised the army and fiercely defended the Commonwealth's eastern borders. Under the
Treaty of Stuhmsdorf, he reclaimed regions of Livonia and the Baltics which were lost during the Polish-Swedish wars. Unlike his father who worshipped the Habsburgs, Władysław sought closer ties with France and married
Marie Louise Gonzaga, daughter of
Charles I Gonzaga, Duke of Mantua, in 1646.
Deluge, rebellions and Vienna (1648–1696) , victor over the
Ottoman Turks at the
Battle of Vienna in 1683. The Commonwealth's power and stability began waning after a series of blows during the following decades. Władysław's brother,
John II Casimir, proved to be weak and impotent. The multicultural and mega-diverse federation already suffered domestic problems. As persecution of religious and ethnic minorities strengthened, several groups started to rebel. A major rebellion of self-governed
Ukrainian Cossacks inhabiting south-eastern borderlands of the Commonwealth rioted against Polish and Catholic oppression of Orthodox
Ukraine in 1648, in what came to be known as the
Khmelnytsky Uprising. It resulted in a Ukrainian request, under the terms of the
Treaty of Pereyaslav, for protection by the Russian Tsar. In 1651, in the face of a growing threat from Poland, and forsaken by his Tatar allies,
Khmelnytsky asked the Tsar to incorporate Ukraine as an autonomous duchy under Russian protection. Russian annexation of Zaporizhian Ukraine gradually supplanted Polish influence in that part of Europe. In the years following, Polish settlers, nobles, Catholics and
Jews became the victims of retaliation massacres instigated by the Cossacks in their dominions. The other blow to the Commonwealth was a Swedish invasion in 1655, known as the
Deluge, which was supported by troops of
Transylvanian Duke
George II Rákóczi and
Frederick William, Elector of Brandenburg. Under the
Treaty of Bromberg in 1657, Catholic Poland was forced to renounce its
suzerainty over Protestant
Prussia; in 1701 the once-insignificant duchy was transformed into the
Kingdom of Prussia, which became a major European power in the 18th century and proved to be Poland's most enduring foe. In the late 17th century, the king of the weakened Commonwealth,
John III Sobieski, allied with Holy Roman Emperor
Leopold I to deal crushing defeats to the
Ottoman Empire. In 1683, the
Battle of Vienna marked the final turning point in the 250-year struggle between the forces of Christian Europe and the
Islamic Ottomans. For its centuries-long opposition to Muslim advances, the Commonwealth would gain the name of
Antemurale Christianitatis (bulwark of Christianity). During the next 16 years, the
Great Turkish War would drive the Turks permanently south of the
Danube River, never again to threaten central Europe. The remaining European powers perpetually meddled in the country's affairs. Upon the death of a king, several royal houses actively intruded in the hope of securing votes for their desired candidates. The practice was common and apparent, and the selection was often the result of hefty bribes directed at corrupt nobles.
Louis XIV of France heavily invested in
François Louis, Prince of Conti, in opposition to
James Louis Sobieski,
Maximilian Emanuel of Bavaria and
Frederick Augustus of Saxony. The latter's conversion from
Lutheranism to Catholicism awed the conservative magnates and
Pope Innocent XII, who in turn voiced their endorsement.
Imperial Russia and
Habsburg Austria also contributed by financing Frederick, whose election took place in June 1697. Many questioned the legality of his elevation to the throne; it was speculated that the Prince of Conti had received more votes and was the rightful heir. Frederick hurried with
his armies to Poland to quell any opposition. He was crowned as Augustus II in September and Conti's brief military engagement near
Gdańsk in November of the same year proved fruitless. The
House of Wettin ruled Poland–Lithuania and
Saxony simultaneously, dividing power between the two states. In spite of his controversial means of attaining power, Augustus II lavishly spent on the arts and left an extensive cultural and architectural (
Baroque) legacy in both countries. In Poland, he expanded
Wilanów and facilitated the refurbishment of the
Warsaw Royal Castle into a modern palatial residence. Countless landmarks and monuments in the city bear a name referencing the Saxon kings, notably
Saxon Garden,
Saxon Axis and the former
Saxon Palace. The period saw the development of urban planning, street allocation, hospitals, schools (
Collegium Nobilium), public parks and libraries (
Załuski Library). First manufactories producing on a mass scale were opened to satisfy the demands of the nobility as consumers. At the height of the
Great Northern War a coalition (
Warsaw Confederation) against Augustus II was formed by
Stanisław Leszczyński and other magnates sponsored by Sweden. The Polish–Lithuanian Commonwealth was formally neutral at this point, as Augustus entered the war as Elector of Saxony. Disregarding Polish negotiation proposals supported by the Swedish parliament, Charles crossed into the Commonwealth and vanquished the Saxe-Polish forces at the
Battle of Kliszów in 1702 and at the
Battle of Pułtusk in 1703. Charles then succeeded in dethroning Augustus and coercing the Sejm (parliament) to replace him with Stanisław in 1704. Augustus regained the throne in 1709, but his own death in 1733 sparked the
War of the Polish Succession in which Stanisław once more attempted to seize the crown, this time with the support of France. The
Pacification Sejm culminated in
Augustus III succeeding his father Frederick Augustus of Saxony. The relative peace and inactivity that followed only weakened Poland's reputation on the world stage.
Aleksander Brückner noted that Polish customs and traditions were abandoned in favour of everything foreign, and neighbouring states continued to exploit Poland to their advantage. It was also during this period that the
Polish Enlightenment began to sprout.
Partitions (1772–1795) in
1772,
1793 and
1795. In 1764, aristocrat
Stanisław August Poniatowski was elected monarch with the connivance and support of his former lover
Catherine the Great, a German noblewoman who became
Empress of Russia. Poniatowski's attempts at reform were met with staunch resistance both internally and externally. Any goal of stabilizing the Commonwealth was dangerous for its ambitious and aggressive neighbours. Like his predecessors, he sponsored artists and architects. In 1765 he founded the
Warsaw Corps of Cadets, the first state school in Poland for all classes of society. In 1773 the king and parliament formed the
Commission of National Education, the first Ministry of Education in European history. In 1792, the king ordered the creation of
Virtuti Militari, the oldest military decoration still in use. Stanisław August also admired the culture of ancient kingdoms, particularly Rome and Greece;
Neoclassicism became the dominant form of architectural and cultural expression. Politically, however, the vast Commonwealth was in steady decline and by 1768, it started to be considered by Russians as a
protectorate of the
Russian Empire despite the fact that it was still an independent state. A majority of control over Poland was central to Catherine's diplomatic and military strategies. Attempts at reform, such as the
Four-Year Sejm's
May Constitution, came too late. The country was
partitioned in three stages by the Russian Empire, the
German Kingdom of Prussia, and the Austrian
Habsburg monarchy. By 1795, the Polish–Lithuanian Commonwealth had been completely erased from the map of Europe. Poland and Lithuania were not re-established as independent countries until 1918. ==State organization and politics==
