Warsaw is the capital of Poland and with almost 1.8 million inhabitants also the largest city in the country. It is located in the Mazovian Voivodeship on Poland's longest river, the Vistula. Warsaw first became the capital of the Polish-Lithuanian noble republic at the end of the 16th century, replacing Krakow, which had previously been the Polish capital. During the partitions of Poland-Lithuania, Warsaw was occupied several times and finally became part of the Prussian province of South Prussia for eleven years. From 1807 to 1815 the city was the capital of the Duchy of Warsaw, a short-lived Napoleonic satellite state; in the annexation of the Kingdom of Poland under Russian suzerainty (the so-called Congress Poland). It was not until the establishment of the Second Polish Republic after the end of World War I that Warsaw was again the capital of an independent Polish state.
At the beginning of World War II, Warsaw was conquered and occupied by the Wehrmacht only after intense fighting and a siege lasting several weeks. Even then, a five-digit number of inhabitants were killed and parts of the city, known not least for its numerous baroque palaces and parks, were already severely damaged. In the course of the subsequent oppression, persecution and murder of the Polish and Jewish population, by far the largest Jewish ghetto under German occupation was established in the form of the Warsaw Ghetto, which served as a collection camp for several hundred thousand people from the city, the surrounding area and even occupied foreign countries, and was also the starting point for deportation to labor and extermination camps.
As a result of the Warsaw Ghetto Uprising from April 18, 1943 and its suppression in early May 1943, the ghetto area was systematically destroyed and its last inhabitants deported and murdered. This was followed in the summer of 1944 by the Warsaw Uprising against the German occupation, which lasted two months and resulted in the deaths of almost two hundred thousand Poles, and after its suppression the rest of Warsaw was also systematically destroyed by German units.
In the post-war period, many historic buildings and downtown areas, including the Warsaw Royal Castle and the Old Town, were rebuilt - a process that continues to this day.
