Warsaw is the capital and largest city of Poland, located on the Vistula in the east-central part of the country. It has an estimated population of 1.86 million, within a larger metropolitan area of 3.27 million residents, and it is a major cultural, political and economic hub. Warsaw originated as a small fishing town in Masovia, rising to prominence in the late 16th century when Sigismund III moved the Polish capital and his royal court from Kraków. It was the de facto capital of the Polish–Lithuanian Commonwealth until 1795 and then the seat of Napoleon's Duchy of Warsaw. The 19th century and its Industrial Revolution brought a demographic boom. Warsaw was bombed and besieged at the start of World War II in 1939, and its infrastructure and population suffered during the systematic razing which followed the Warsaw Uprising in 1944. The modern city features many historic monuments, including the reconstructed Old Town, designated a World Heritage Site.
