Poland is a Central European country with a population of about 37.96 million people. It is bordered by Germany to the west, the Czech Republic and Slovakia to the south, Ukraine and Belarus to the east, and Lithuania, Latvia, and the Baltic Sea to the north. Poland has a long history, with evidence of human presence dating back to the Paleolithic era. It underwent a period of strong international influence during the Middle Ages, with the rising of the Kingdom of Poland under the rule of kings like Mieszko I and Boleslaw Chrobry, and was then briefly occupied by the Swedish-Brandenburgian state. In the 18th century, Poland was partitioned between Austria, Prussia, and Russia, a situation that lasted until Polish independence was regained in 1918 with the Treaty of Riga.
Poland was then occupied by Nazi Germany in World War II, and is today a multi-party democracy. Poland is known for its natural beauty, with a variety of scenic landscapes and forests, valleys and rivers, ski resorts, beaches, and numerous national parks. It is a very diverse country with a wide range of cultural and historical sites.
