Radom is a city in east-central Poland, located approximately south of the capital, Warsaw. It is situated on the Mleczna River in the Masovian Voivodeship (since 1999), having previously been the seat of a separate Radom Voivodeship (1975–1998). Radom is the fourteenth-largest city in Poland and the second-largest in its province with a population of 206,946 For centuries, Radom was part of the Sandomierz Province of the Kingdom of Poland and the later Polish–Lithuanian Commonwealth. Despite being part of the Masovian Voivodeship, the city historically belongs to Lesser Poland. It was a significant center of administration, having served as seat of the Crown Council which ratified the Pact of Vilnius and Radom between Lithuania and Poland in 1401. 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 the June 1976 protests. The city is home to the biennial Radom Air Show, the largest air show in the country, held during the last weekend of August. "Radom" is also the popular unofficial name for a semiautomatic FB Vis pistol, which was produced from 1935 to 1944 by Radom's Łucznik Arms Factory. The city continues to produce military firearms for the Polish Armed Forces. The international Radom Jazz Festival and the International Gombrowicz Theater Festival are held in the city. History Radom's original settlement dates back to the 8th–9th century. It was an early medieval town in the valley of the Mleczna River (on the approximate site of present-day Old Town). In the second half of the 10th century, it became a gord, called Piotrówka, which was protected by a rampart and a moat. Due to convenient location on the edge of a large wilderness, and its proximity to the border of Lesser Poland and Mazovia, Radom quickly emerged as an important administrative center of the early Kingdom of Poland. Piotrówka was probably named after St. Peter church, which in 1222 was placed under the authority of a Benedictine Abbey in nearby Sieciechów. The church no longer exists; the oldest still-extant church in Radom is St. Wacław, founded in the 13th century by Prince of Sandomierz Leszek I the White. The first documented mention of Radom comes from the year 1155, in a bull of Pope Adrian IV (villam iuxta Rado, que vocatur Zlauno, or a village near Radom, called Sławno). By 1233, Radom was the seat
