Radzyń Podlaski pronounced [ˈrad͡zɨɲ pɔdˈlaskʲi] is a town in eastern Poland, about 60 km north of Lublin, with 15,808 inhabitants (2017).

Radzyń lies on the Białka River within the South Podlasie Lowland, at the height of 150 metres (490 ft) above sea level.

In 1456, first Roman Catholic parish at Radzyń was created, and in 1468, the town was incorporated based on Magdeburg rights.

Radzyń was a private town, administratively located in the Lublin Voivodeship in the Lesser Poland Province of the Polish Crown.

In November 1918, Poland regained independence, and the occupying German forces opened fire on Poles who tried to liberate the town,[3] but it was still reintegrated with the reborn Polish state.

During the joint German-Soviet invasion of Poland, which started World War II, on September 9, 1939, Radzyń was bombed by the Luftwaffe.

In late September of that year, it was one of centers of Polish resistance, with units of Independent Operational Group Polesie stationed there for some time.

In June 1940, during the AB-Aktion, the Germans carried out mass arrests of Poles, many of whom were afterwards imprisoned in the Lublin Castle and deported to concentration camps.

Its interior was destroyed twice: in 1915 by Imperial Russian troops, and in 1944 by the Wehrmacht during the occupation of Poland in World War II.
