Radom is a city in central Poland with 219,703 inhabitants (2013). It is located 100km south of Poland's capital, Warsaw, on the Mleczna River, in (as of 1999) the Masovian Voivodeship, having previously been the capital of Radom Voivodeship (1975–1998). Despite being part of the Masovian Voivodeship, the city historically belongs to Lesser Poland. For centuries, Radom was part of the Sandomierz Voivodeship of the Kingdom of Poland and the later Polish-Lithuanian Commonwealth. It was an important center of administration, having served as seat of the Crown Council. The Pact of Vilnius and Radom was signed there in 1401, and the Nihil novi and Łaski's Statute were adopted by the Sejm at Radom's Royal Castle in 1505. In 1976, it was a center of anti Communist street protests.The city is home to the biennial Radom Air Show, the largest and best-attended air show in Poland, held during the last weekend of August. "Radom" is also the popular unofficial name for a semiautomatic 9 mm Para pistol of Polish design (the Model 35/ViS-35) which was produced from 1935 to 1944 at the national arsenal located in the city. The Łucznik Arms Factory (still located in Radom) continues to produce modern military firearms.
