Poland<!-- Do not add English pronunciation per Wikipedia:Manual of Style/Lead section. -->, officially the Republic of Poland, is a country in Central Europe. It extends from the Baltic Sea in the north to the Sudetes and Carpathian Mountains in the south, and borders Lithuania and Russia to the northeast; Belarus and Ukraine to the east; Slovakia and the Czech Republic to the south; and Germany to the west. The territory has a varied landscape, diverse ecosystems, and a temperate climate. Poland is composed of sixteen voivodeships and is the fifth most populous member state of the European Union (EU), with over 38 million people, and the fifth largest EU country by land area, covering . The capital and largest city is Warsaw; other major cities include Kraków, Wrocław, Łódź, Poznań, and Gdańsk.
Prehistoric human activity on Polish soil dates to the Lower Paleolithic, with continuous settlement since the end of the Last Glacial Period. Culturally diverse throughout late antiquity, in the early medieval period the region became inhabited by the West Slavic tribal Polans, who gave Poland its name. The process of establishing statehood coincided with the conversion of a pagan ruler of the Polans to Christianity in 966 under the auspices of the Roman Catholic Church. The Kingdom of Poland emerged in 1025, and in 1569 cemented its long-standing association with Lithuania, thus forming the Polish–Lithuanian Commonwealth. At the time, the Commonwealth was one of the great powers of Europe, with an elective monarchy and a uniquely liberal political system, which adopted Europe's first modern constitution in 1791.
With the passing of the prosperous Polish Golden Age, the country was partitioned by neighbouring states at the end of the 18th century. At the end of World War I in 1918, Poland regained its independence with the founding of the Second Polish Republic, which emerged victorious in various conflicts of the interbellum period. In September 1939, the invasion of Poland by Germany and the Soviet Union marked the beginning of World War II, which resulted in the Holocaust and millions of Polish casualties as well as extensive border and demographic changes. Forced into the Eastern Bloc in the global Cold War, the Polish People's Republic was a signatory of the Warsaw Pact. Through the 1980 emergence and contributions of the Solidarity movement, which initiated the fall of the Iron Curtain, the communist government was dissolved and Poland as the first of the communist countries re-established itself as a liberal democracy in 1989, and held free elections.
Poland is a parliamentary republic with its bicameral legislature comprising the Sejm and the Senate. Considered a middle power and a regional power, it is a developed market and high-income economy. In terms of nominal GDP, it is the 20th largest economy in the world and the sixth in the European Union, and fifth largest by PPP-adjusted GDP in the EU. Poland has a high standard of living, safety, and economic freedom, as well as free university education and universal health care. It has 17 UNESCO World Heritage Sites, over 100 Historic Monuments and 23 national parks. Poland is a founding member of the United Nations, and a member of the Council of Europe, World Trade Organisation, OECD, NATO, and EU (including the Schengen Area).
Etymology
The native Polish name for Poland is . It is believed that the name derives from the Polans, a West Slavic tribe who inhabited the Warta River basin of present-day Greater Poland region (6th–8th century CE). The tribe's name stems from the Proto-Slavic noun pole, meaning field, which itself originates from the Proto-Indo-European word *pleh₂- indicating flatland. The etymology alludes to the topography of the region and the flat landscape of Greater Poland. During the Middle Ages, the Latin form Polonia was widely used throughout Europe.
The country's alternative archaic name is Lechia and its root syllable remains in official use in several languages, notably Hungarian, Lithuanian, and Persian. The exonym possibly derives from either Lech, a legendary ruler of the Lechites, or from the Lendians, a West Slavic tribe that dwelt on the south-easternmost edge of Lesser Poland. The origin of the tribe's name lies in the Old Polish word lęda (plain). Initially, both names Lechia and Polonia were used interchangeably when referring to Poland by chroniclers during the Middle Ages.
History
Prehistory and protohistory
thumb|right|A reconstruction of a [[Bronze Age Lusatian culture settlement in Biskupin, 8th century BC]]
The first Stone Age archaic humans and Homo erectus species settled what was to become Poland approximately 500,000 years ago, though the ensuing hostile climate prevented early humans from founding more permanent encampments. The arrival of Homo sapiens and anatomically modern humans coincided with the climatic discontinuity at the end of the Last Glacial Period (Northern Polish glaciation 10,000 BC), when Poland became habitable. Neolithic excavations indicated broad-ranging development in that era; the earliest evidence of European cheesemaking (5500 BC) was discovered in Polish Kuyavia, and the Bronocice pot is incised with the earliest known depiction of what may be a wheeled vehicle (3400 BC).
The period spanning the Bronze Age and the Early Iron Age (1300 BC–500 BC) was marked by an increase in population density, establishment of palisaded settlements (gords) and the expansion of Lusatian culture. A significant archaeological find from the protohistory of Poland is a fortified settlement at Biskupin, attributed to the Lusatian culture of the Late Bronze Age (mid-8th century BC).
Throughout antiquity (400 BC–500 AD), many distinct ancient populations inhabited the territory of present-day Poland, notably Celtic, Scythian, Germanic, Sarmatian, Baltic and Slavic tribes. Furthermore, archaeological findings confirmed the presence of Roman Legions sent to protect the amber trade. The Polish tribes emerged following the second wave of the Migration Period around the 6th century AD; Beginning in the early 10th century, the Polans would come to dominate other Lechitic tribes in the region, initially forming a tribal federation and later a centralised monarchical state.
Kingdom of Poland
thumb|left|Poland under the rule of Duke [[Mieszko I, whose acceptance of Christianity under the auspices of the Roman Church and the Baptism of Poland marked the beginning of statehood in 966. His son, Bolesław I the Brave, was crowned king in 1025]]
Poland began to form into a recognisable unitary and territorial entity around the middle of the 10th century under the Piast dynasty. In 966, the ruler of the Polans, Mieszko I, accepted Western Christianity under the auspices of the Roman Catholic Church which was tantamount to the adoption of Christianity by Poland. In 968, a missionary bishopric was established in Poznań. An incipit titled Dagome iudex first defined Poland's geographical boundaries with its capital in Gniezno and affirmed that its monarchy was under the protection of the Apostolic See. The country's early origins were described by Gallus Anonymus in , the oldest Polish chronicle. An important national event of the period was the martyrdom of Saint Adalbert, who was killed by Prussian pagans in 997 and whose remains were reputedly bought back for their weight in gold by Mieszko's successor, Bolesław I the Brave. Also, Otto bestowed upon Bolesław royal regalia and a replica of the Holy Lance, which were later used at his coronation as the first King of Poland , when Bolesław received permission for his coronation from Pope John XIX. Bolesław also expanded the realm considerably by seizing parts of German Lusatia, Czech Moravia, Upper Hungary, and southwestern regions of the Kievan Rus'.

The transition from paganism in Poland was not instantaneous and resulted in the pagan reaction of the 1030s. In 1031, Mieszko II Lambert lost the title of king and fled amidst the violence. The unrest led to the transfer of the capital to Kraków in 1038 by Casimir I the Restorer. In 1076, Bolesław II re-instituted the office of king, but was banished in 1079 for murdering his opponent, Bishop Stanislaus. In 1138, the country fragmented into five principalities when Bolesław III Wrymouth divided his lands among his sons. In 1226, Konrad I of Masovia invited the Teutonic Knights to aid in combating the Baltic Prussians; a decision that later led to centuries of warfare with the Knights.
In the first half of the 13th century, Henry I the Bearded and Henry II the Pious aimed to unite the fragmented dukedoms, but the Mongol invasion and the death of Henry II in battle hindered the unification. As a result of the devastation which followed, depopulation and the demand for craft labour spurred a migration of German and Flemish settlers into Poland, which was encouraged by the Polish dukes. In 1264, the Statute of Kalisz introduced unprecedented autonomy for the Polish Jews, who came to Poland fleeing persecution elsewhere in Europe.
In 1320, Władysław I the Short became the first king of a reunified Poland since Przemysł II in 1296, and the first to be crowned at Wawel Cathedral in Kraków. Beginning in 1333, the reign of Casimir III the Great was marked by developments in castle infrastructure, army, judiciary and diplomacy. Under his authority, Poland transformed into a major European power; he instituted Polish rule over Ruthenia in 1340 and imposed quarantine that prevented the spread of Black Death. In 1364, Casimir inaugurated the University of Kraków, one of the oldest institutions of higher learning in Europe. Upon his death in 1370, the Piast dynasty came to an end. He was succeeded by his closest male relative, Louis of Anjou, who ruled Poland, Hungary, and Croatia in a personal union. Louis' younger daughter Jadwiga became Poland's first female monarch in 1384. The partnership between Poles and Lithuanians brought the vast multi-ethnic Lithuanian territories into Poland's sphere of influence and proved beneficial for its inhabitants, who coexisted in one of the largest European political entities of the time.
In the Baltic Sea region, the struggle of Poland and Lithuania with the Teutonic Knights continued and culminated at the Battle of Grunwald in 1410, where a combined Polish–Lithuanian army inflicted a decisive victory against them. In 1493, John I Albert sanctioned the creation of a bicameral parliament (the Sejm) composed of a lower house, the chamber of deputies, and an upper house, the chamber of senators. The Nihil novi act adopted by the Polish General Sejm in 1505, transferred most of the legislative power from the monarch to the parliament, an event which marked the beginning of the period known as Golden Liberty, when the state was ruled by the seemingly free and equal Polish nobles.

The 16th century saw Protestant Reformation movements making deep inroads into Polish Christianity, which resulted in the establishment of policies promoting religious tolerance, unique in Europe at that time. In Poland, Nontrinitarian Christianity became the doctrine of the so-called Polish Brethren, who separated from their Calvinist denomination and became the co-founders of global Unitarianism.
The European Renaissance evoked under Sigismund I the Old and Sigismund II Augustus a sense of urgency in the need to promote a cultural awakening. During the Polish Golden Age, the nation's economy and culture flourished. The Italian-born Bona Sforza, daughter of the Duke of Milan and queen consort to Sigismund I, made considerable contributions to architecture, cuisine, language and court customs at Wawel Castle. The latter coincided with a period of prosperity. The Polish-dominated union thereafter became a leading power and a major cultural entity, exercising political control over parts of Central, Eastern, Southeastern and Northern Europe. The Polish–Lithuanian Commonwealth occupied approximately at its peak and was the largest state in Europe. Simultaneously, Poland imposed Polonisation policies in newly acquired territories which were met with resistance from ethnic and religious minorities. When he left Poland to become King of France, his successor, Stephen Báthory, led a successful campaign in the Livonian War, granting Poland more lands across the eastern shores of the Baltic Sea. State affairs were then headed by Jan Zamoyski, the Crown Chancellor. Stephen's successor, Sigismund III, defeated a rival Habsburg electoral candidate, Archduke Maximilian III, in the War of the Polish Succession (1587–1588). In 1592, Sigismund succeeded his father John Vasa, in Sweden. The Polish-Swedish union endured until 1599, when he was deposed by the Swedes.

In 1609, Sigismund invaded Russia which was engulfed in a civil war, Sigismund's long reign in Poland coincided with the Silver Age. The liberal Władysław IV effectively defended Poland's territorial possessions but after his death the vast Commonwealth began declining from internal disorder and constant warfare.
In 1648, the Polish hegemony over Ukraine sparked the Khmelnytsky Uprising, followed by the decimating Swedish Deluge during the Second Northern War, and Prussia's independence in 1657. The Saxon era, under Augustus II and Augustus III, saw neighbouring powers grow in strength at the expense of Poland. Both Saxon kings faced opposition from Stanisław Leszczyński during the Great Northern War (1700) and the War of the Polish Succession (1733).
Partitions
thumb|upright|right|[[Stanisław II Augustus, the last King of Poland, reigned from 1764 until his abdication on 25 November 1795.]]
The royal election of 1764 resulted in the elevation of Stanisław II Augustus Poniatowski to the monarchy. His candidacy was extensively funded by his sponsor and former lover, Empress Catherine II of Russia. The new king maneuvered between his desire to implement necessary modernising reforms, and the necessity to remain at peace with surrounding states. His ideals led to the formation of the 1768 Bar Confederation, a rebellion directed against the Poniatowski and all external influence, which ineptly aimed to preserve Poland's sovereignty and privileges held by the nobility. The failed attempts at government restructuring as well as the domestic turmoil provoked its neighbours to invade.
In 1772, the First Partition of the Commonwealth by Prussia, Russia, and Austria took place, an act which the Partition Sejm, under considerable duress, eventually ratified as a fait accompli. Corporal punishment of schoolchildren was officially prohibited in 1783. Poniatowski was the head figure of the Enlightenment, encouraged the development of industries, and embraced republican neoclassicism. For his contributions to the arts and sciences, he was awarded a Fellowship of the Royal Society.
In 1791, the Great Sejm parliament adopted the 3 May Constitution, the first set of supreme national laws, and introduced a constitutional monarchy. The Targowica Confederation, an organisation of nobles and deputies opposing the act, appealed to Catherine and caused the 1792 Polish–Russian War. Fearing the reemergence of Polish hegemony, Russia and Prussia arranged and, in 1793, executed the Second Partition, which left the country deprived of territory and incapable of independent existence. On 24 October 1795, the Commonwealth was partitioned for the third time and ceased to exist as a territorial entity. Stanisław Augustus, the last King of Poland, abdicated the throne on 25 November 1795.
Era of insurrections
thumb|right|upright=1.3|The [[partitions of Poland, carried out by the Kingdom of Prussia (blue), the Russian Empire (brown), and the Austrian Habsburg Monarchy (green) in 1772, 1793 and 1795]]
The Polish people rose several times against the partitioners and occupying armies. An unsuccessful attempt at defending Poland's sovereignty took place in the 1794 Kościuszko Uprising, where a popular and distinguished general Tadeusz Kościuszko, who had several years earlier served under George Washington in the American Revolutionary War, led Polish insurgents. Despite the victory at the Battle of Racławice, his ultimate defeat ended Poland's independent existence for 123 years.
In 1806, an insurrection organised by Jan Henryk Dąbrowski liberated western Poland ahead of Napoleon's advance into Prussia during the War of the Fourth Coalition. In accordance with the 1807 Treaty of Tilsit, Napoleon proclaimed the Duchy of Warsaw, a client state ruled by his ally Frederick Augustus I of Saxony. The Poles actively aided French troops in the Napoleonic Wars, particularly those under Józef Poniatowski who became Marshal of France shortly before his death at Leipzig in 1813. In the aftermath of Napoleon's exile, the Duchy of Warsaw was abolished at the Congress of Vienna in 1815 and its territory was divided into Russian Congress Kingdom of Poland, the Prussian Grand Duchy of Posen, and Austrian Galicia with the Free City of Kraków.
