History of Poland in the context of "Bohdan Khmelnytskyi"

Polish people, or Poles, are a West Slavic ethnic group and nation who share a common history, culture, the Polish language and are identified with the country of Poland in Central Europe. The preamble to the Constitution of the Republic of Poland defines the Polish nation as comprising all the citizens of Poland, regardless of heritage or ethnicity. The majority of Poles adhere to Roman Catholicism.

The population of self-declared Poles in Poland is estimated at 37,394,000 out of an overall population of 38,512,000 (based on the 2011 census), of whom 36,522,000 declared Polish alone. A wide-ranging Polish diaspora (the Polonia) exists throughout Eurasia, the Americas, and Australasia. Today, the largest urban concentrations of Poles are within the Warsaw metropolitan area and the Katowice urban area.

The history of Poland from 1945 to 1989 spans the period of Marxist–Leninist regime in Poland after the end of World War II. These years, while featuring general industrialization, urbanization and many improvements in the standard of living, were marred by early Stalinist repressions, social unrest, political strife and severe economic difficulties.Near the end of World War II, the advancing Soviet Red Army, along with the Polish Armed Forces in the East, pushed out the Nazi German forces from occupied Poland. In February 1945, the Yalta Conference sanctioned the formation of a provisional government of Poland from a compromise coalition, until postwar elections. Joseph Stalin, the leader of the Soviet Union, manipulated the implementation of that ruling. A practically communist-controlled Provisional Government of National Unity was formed in Warsaw by ignoring the Polish government-in-exile based in London since 1940.

During the subsequent Potsdam Conference in July–August 1945, the three major Allies ratified a massive westerly shift of Poland's borders and approved its new territory between the Oder–Neisse line and the Curzon Line. The area of Poland was reduced in comparison to its pre-World War II extent and geographically resembled that of the medieval early Piast dynasty era. Following the destruction of the Polish-Jewish population in the Holocaust, the flight and expulsion of Germans in the west, resettlement of Ukrainians in the east, and the expulsion and resettlement of Poles from the Eastern Borderlands (Kresy), Poland became for the first time in its history an ethnically homogeneous nation-state without prominent minorities. The new government solidified its political power, while the Polish United Workers' Party (PZPR) under Bolesław Bierut gained firm control over the country, which would remain an independent state within the Soviet sphere of influence. The July Constitution was promulgated on 22 July 1952 and the country officially became the Polish People's Republic (PRL).

The Battle of Grunwald is a painting by Jan Matejko depicting the Battle of Grunwald and the victory of the allied Crown of the Kingdom of Poland and Grand Duchy of Lithuania over the Teutonic Order in 1410. The canvas dates to 1878 and is one of the most heroic representations of the history of Poland and Lithuania. It is displayed in the National Museum in Warsaw.

The painting's main focus is the death scene of the Grand Master of the Teutonic Order, Ulrich von Jungingen; another central figure is the Lithuanian grand duke Vytautas the Great, dressed in red with a raised sword. The painting has been both hailed and criticized for its complexity. It is one of Matejko's most recognizable works, and has likely contributed to the popular image of the battle of Grunwald, and its enduring fame in Polish and Lithuanian consciousness.

Jan Alojzy Matejko (Polish pronunciation: [ˈjan aˈlɔjzɨ maˈtɛjkɔ] ; also known as Jan Mateyko; 24 June 1838 – 1 November 1893) was a Polish painter, a leading 19th-century exponent of history painting, known for depicting nodal events from Polish history. His works include large scale oil paintings such as Stańczyk (1862), Rejtan (1866), Union of Lublin (1869), Astronomer Copernicus, or Conversations with God (1873), or Battle of Grunwald (1878). He was the author of numerous portraits, a gallery of Polish monarchs in book form, and murals in St. Mary's Basilica, Kraków. He is considered by many as the most celebrated Polish painter, and sometimes as the "national painter" of Poland.

Matejko spent most of his life in Kraków. He enrolled at the Kraków Academy of Fine Arts at age fourteen, where he studied under notable artists such as Wojciech Korneli Stattler and Władysław Łuszczkiewicz and completed his first major historical painting in 1853. His early exposure to revolutions in Kraków and the military service of his brothers influenced his artistic themes. After studying art in Munich and Vienna, he returned to Kraków and set up a studio. He gradually gained recognition, selling key paintings that settled his debts and created some of his most famous works, including Stańczyk and Skarga's Sermon. Matejko's art played a key role in promoting Polish history and national identity at a time when Poland was partitioned and lacked political autonomy.

Zynoviy Bohdan Mykhailovych Khmelnytsky of the Abdank coat of arms (1595 – 6 August 1657) was a Ruthenian nobleman and military commander of Zaporozhian Cossacks as Hetman of the Zaporozhian Host, which was then under the suzerainty of the Polish–Lithuanian Commonwealth. He led the Cossacks to victory in a successful uprising against the Commonwealth and its magnates (1648–1654) that resulted in the creation of an independent Cossack state in Ukraine.

In 1648–1649, the Cossacks under Khmelnytskyi's leadership massacred tens of thousands of Poles and Jews, with more handed over as yasir (slaves) to his Crimean Tatar allies, one of the most traumatic events in Polish and Jewish history. Under his rule of the newly-established Cossack state, the massacres continued until at least 1652. In 1654, Khmelnytsky concluded the Treaty of Pereiaslav with the Russian Tsar and allied the Cossack Hetmanate with Tsardom of Russia, thus placing Ukraine under Russian protection.

The Lusatian culture existed in the later Bronze Age and early Iron Age (1300–500 BC) in most of what is now Poland and parts of the Czech Republic, Slovakia, eastern Germany and western Ukraine. It covers the Periods Montelius III (early Lusatian culture) to V of the Northern European chronological scheme. It has been associated or closely linked with the Nordic Bronze Age. Hallstatt influences can also be seen particularly in ornaments (fibulae, pins) and weapons.

Mieszko I (Polish pronunciation: [ˈmjɛʂkɔ ˈpjɛrfʂɨ] ; c. 930 – 25 May 992) was Duke of Poland from 960 until his death in 992 and the founder of the first unified Polish state, the Civitas Schinesghe. A member of the Piast dynasty, he was the first Christian ruler of Poland and continued the policies of both his father Siemomysł and his grandfather Lestek, who initiated a process of unification among the Polish tribes and the creation of statehood.

According to existing sources, Mieszko I was a potent politician, a talented military leader and a charismatic ruler. Through both alliances and military force, he extended ongoing Polish conquests. Early in his reign, he subjugated Kuyavia and likely Gdańsk Pomerania and Masovia. For most of his reign, Mieszko I waged war for control of Western Pomerania. He eventually annexed it to the vicinity of the lower Oder River. His internal reforms were aimed at expanding and improving the so-called war monarchy system. During the last years of his life, he fought the Bohemian state and captured Silesia and lands now constituting Lesser Poland.

In the history of Poland, a royal city or royal town (Polish: miasto królewskie) was an urban settlement within the crown lands (Polish: królewszczyzna).

The most influential royal cities enjoyed voting rights during the free election period in Poland (1572–1791). These cities were Gdańsk, Warsaw, Kraków, Poznań, Lwów, Wilno, Toruń, Lublin, Kamieniec and Elbląg. Other important royal cities included Gniezno (ecclesiastical capital of Poland and former capital of early medieval Poland), Płock (former capital of medieval Poland), Piotrków (second most important political center of Poland in the early and mid-16th century as the main location of the Sejm, and then the main Crown Tribunal location alongside Lublin, thus one of the two judiciary capitals of Poland), Grodno (de facto capital of the Polish–Lithuanian Commonwealth in the 1580s and then the general sejm location alongside Warsaw), Bydgoszcz and Kalisz (temporary locations of the Crown Tribunal), and Sandomierz, Przemyśl, Kazimierz.

The culture of Poland (Polish: Kultura Polski or kultura polska) is the product of its geography and distinct historical evolution, which is closely connected to an intricate thousand-year history. Poland has a Roman Catholic majority, and religion plays an important role in the lives of many Polish people. The unique character of Polish culture developed as a result of its geography at the confluence of various European regions.

It is theorised and speculated that ethnic Poles are the combination of descendants of West Slavs and people indigenous to the region including Celts, Balts and Germanic tribes which were gradually Polonized after Poland's Christianization by the Catholic Church in the 10th century. Over time Polish culture has been profoundly influenced by its interweaving ties with the Germanic, Baltic, Jewish, Latinate and to a lesser extent; Byzantine and Ottoman cultures as well as in continual dialogue with the many other ethnic groups and minorities living in Poland.
