context_page_description: Poland, officially the Republic of Poland, is a country located in Central Europe. It is divided into 16 administrative subdivisions, covering an area of 312,696 square kilometres, and has a largely temperate seasonal climate. With a population of nearly 38.5 million people, Poland is the fifth most populous member state of the European Union. Poland's capital and largest metropolis is Warsaw. Other major cities include Kraków, Łódź, Wrocław, Poznań, Gdańsk, and Szczecin.
  Poland is bordered by the Baltic Sea, Lithuania, and Russia's Kaliningrad Oblast to the north, Belarus and Ukraine to the east, Slovakia and the Czech Republic to the south, and Germany to the west.
  The history of human activity on Polish soil spans thousands of years. Throughout the late antiquity period it became extensively diverse, with various cultures and tribes settling on the vast Central European Plain. However, it was the Western Polans who dominated the region and gave Poland its name. The establishment of Polish statehood can be traced to 966, when the pagan ruler of a realm coextensive with the territory of present-day Poland embraced Christianity and converted to Catholicism.
context_section_description: Poland began to form into a recognizable unitary and territorial entity around the middle of the 10th century under the Piast dynasty. Poland's first historically documented ruler, Mieszko I, accepted Christianity, as the rightful religion of his realm, under the auspices of the Latin Church with the Baptism of Poland in 966. The bulk of the population converted in the course of the next few centuries. In 1000, Boleslaw the Brave, continuing the policy of his father Mieszko, held a Congress of Gniezno and created the metropolis of Gniezno and the dioceses of Kraków, Kołobrzeg, and Wrocław. However, the pagan unrest led to the transfer of the capital to Kraków in 1038 by Casimir I the Restorer.
  In 1109, Prince Bolesław III Wrymouth defeated the King of Germany Henry V at the Battle of Hundsfeld, stopping the German incursion into Poland. The clash between Bolesław III and Henry V was documented by Gallus Anonymus in his 1118 chronicle. In 1138, Poland fragmented into several smaller duchies when Bolesław divided his lands among his sons. In 1226, Konrad I of Masovia, one of the regional Piast dukes, invited the Teutonic Knights to help him fight the Baltic Prussian pagans; a decision that led to centuries of warfare with the Knights. In 1264, the Statute of Kalisz or the General Charter of Jewish Liberties introduced numerous right for the Jews in Poland, leading to a nearly autonomous "nation within a nation".
  In the middle of the 13th century, the Silesian branch of the Piast dynasty (Henry I the Bearded and Henry II the Pious, ruled 1238–1241) nearly succeeded in uniting the Polish lands, but the Mongols invaded the country from the east and defeated the combined Polish forces at the Battle of Legnica where Duke Henry II the Pious died. In 1320, after a number of earlier unsuccessful attempts by regional rulers at uniting the Polish dukedoms, Władysław I consolidated his power, took the throne and became the first king of a reunified Poland. His son, Casimir III (reigned 1333–1370), has a reputation as one of the greatest Polish kings, and gained wide recognition for improving the country's infrastructure. He also extended royal protection to Jews, and encouraged their immigration to Poland. Casimir III realized that the nation needed a class of educated people, especially lawyers, who could codify the country's laws and administer the courts and offices. His efforts to create an institution of higher learning in Poland were finally rewarded when Pope Urban V granted him permission to open the University of Kraków.
  The Golden Liberty of the nobles began to develop under Casimir's rule, when in return for their military support, the king made a series of concessions to the nobility and establishing their legal status as superior to that of the townsmen. When Casimir the Great died in 1370, leaving no legitimate male heir, the Piast dynasty came to an end.
  During the 13th and 14th centuries, Poland became a destination for German, Flemish and to a lesser extent Walloon, Danish and Scottish migrants. Also, Jews and Armenians began to settle and flourish in Poland during this era (see History of the Jews in Poland and Armenians in Poland).
  The Black Death, a plague that ravaged Europe from 1347 to 1351, did not significantly affect Poland, and the country was spared from a major outbreak of the disease. The reason for this was the decision of Casimir the Great to quarantine the nation's borders.
