The town was founded in 1742 by Moravian immigrants. As members of the Moravian Church, they fled from persecution in their Catholic homeland. The name Niesky is the Germanised version of the Czech word nízký ("low").
Niesky was administered by the Moravian Church until 1892, when a separate civil administration was established.[3] In 1931 it obtained a coat of arms, and in 1935 it was granted town rights.[3] In 1935 a Catholic church was opened.[3]
In 1926 the architect Konrad Wachsmann worked in the timber construction firm Christoph & Unmack AG.
During World War II, the Germans established and operated the AL Nieskysubcamp of the Gross-Rosen concentration camp, whose prisoners were mostly Poles, Russians, Jews and Yugoslavs, but also Czechs and Frenchmen, and hundreds of whom died.[4] The Germans evacuated the prisoners in February 1945, leaving only those unable to walk in the camp. During the march, weak prisoners and those unable to continue walking were murdered by the Germans and buried in forests along the way.[4] The prisoners remaining in the camp were liberated by the Polish Second Army which captured the town on 18 April 1945.[4] On 26 July 1945 the city issued three postage stamps of its own.
