Poland, officially the Republic of Poland, is a country in Central Europe. Poland is bordered by Germany to the west; the Czech Republic and Slovakia to the south; Ukraine, Belarus and Lithuania to the east; and the Baltic Sea and Kaliningrad Oblast, a Russian exclave, to the north. The total area of Poland is 312,679 km² (120,728 sq mi), making it the 69th largest country in the world and 9th in Europe. Poland has a population of over 38.5 million people, which makes it the 33rd most populous country in the world.
The establishment of a Polish state is often identified with the adoption of Christianity by its ruler Mieszko I in 966 (see Baptism of Poland), when the state covered territory similar to that of present-day Poland. Poland became a kingdom in 1025, and in 1569 it cemented a long association with the Grand Duchy of Lithuania by uniting to form the Polish-Lithuanian Commonwealth. The Commonwealth collapsed in 1795. Poland regained its independence in 1918 after World War I but lost it again in World War II, occupied by Nazi Germany and the Soviet Union. Poland lost over six million citizens in World War II, and emerged several years later as a communist country within the Eastern Bloc under the control of the Soviet Union. In 1989 communist rule was overthrown and Poland became what is constitutionally known as the "Third Polish Republic". Poland is a unitary state made up of sixteen voivodeships. Poland is also a member of the European Union, NATO and OECD. Poland’s territory extends across several geographical regions. In the northwest is the Baltic seacoast, which extends from the Bay of Pomerania to the Gulf of Gdansk. This coast is marked by several spits, coastal lakes (former bays that have been cut off from the sea), and dunes. The largely straight coastline is indented by the Szczecin Lagoon, the Bay of Puck, and the Vistula Lagoon. The center and parts of the north lie within the Northern European Lowlands. Rising gently above these lowlands is a geographical region comprising the four hilly districts of moraines and moraine-dammed lakes formed during and after the Pleistocene ice age. These lake districts are the Pomeranian Lake District, the Greater Polish Lake District, the Kashubian Lake District, and the Masurian Lake District. The Masurian Lake District is the largest of the four and covers much of northeastern Poland. The lake districts form part of the Baltic Ridge, a series of moraine belts along the southern shore of the Baltic Sea. South of the Northern European Lowlands lie the regions of Silesia and Masovia, which are marked by broad ice-age river valleys. Farther south lies the Polish mountain region, including the Sudetes, the Cracow-Cz?stochowa Upland, the ?wi?tokrzyskie Mountains, and the Carpathian Mountains, including the Beskids. The highest part of the Carpathians is the Tatra Mountains, along Poland’s southern border. |
