Krupka (Czech pronunciation: [ˈkrupka]; German: Graupen) is a town in the north-western part of the Czech Republic, in the Ústí nad Labem Region. From 1938 to 1945 it was one of the municipalities in Sudetenland. It has about 14,000 inhabitants. There are 11 town parts in Krupka: Krupka, Bohosudov, Unčín, Maršov, Nové Modlany, Vrchoslav, Soběchleby, Horní Krupka, Habartice, Fojtovice and Mohelnice.
The fake thought is that the name of this town is derived from the mining of pewter (in Czech "krupky cínu") that was mined there. The name Krupka was created from Old-Czech word "krupý" which means something like large. In connection with the mining, there was created a so-called: “Příhraniční naučná stezka” – educational pathway leading from the Czech side to the German one and back and showing some important as well as beautiful locations.
The Czechs are the majority, but Krupka is a little cosmopolitan town. Some minorities live there as signs of last regimes or political situations. There are some German or scions of them who became Czechs by years. Germans were here on inviting of Czech kings in the Middle Age, but a result of the World War 2 and followed Benešovy dekrety meant for German people to be moved back to Germany, because lots of them were cooperating with Nazists (not all of them, for example Herta Lindgren - the park in the centre of town was given her name). There are also some Vietnamese who came to the Czech Republic (that time Czechoslovakia) during the communism. They are shopkeepers or pubkeepers, the others are occupied in their national friends´ firms. Peharps the most plentiful minority in Krupka, are the Roma. They are placed in the part called Maršov, exactly at Horní Sídliště. There are lots of problems with some of them. There is a big criminality at Horní Sídliště and most of the Romani are the unemployed. The next, say, group of people living in Krupka are Czechs who had lived in Ukraine and later Soviet Union had to move back to the Czechoslovakia after the World War 2. These people are called "Volynští Češi" or "Volyňáci".
