The Częstochowa Ghetto was a Jewish ghetto set up by Nazi Germany in the city of Częstochowa in south-central Poland, for the purpose of persecution and exploitation of local Jews during the German occupation of Poland. The approximate number of people confined to the ghetto at its beginning was around 40,000 and at its peak – right before mass deportations – 48,000. In late 1942 most ghetto inmates were delivered by Holocaust trains to their deaths at the Treblinka extermination camp. In June 1943, the remaining ghetto inhabitants launched the Częstochowa Ghetto Uprising, which was extinguished after a few days of fighting.

The official order for the creation of the Ghetto was issued on April 9, 1941 by Stabshauptmann Richard Wendler. In addition to Jews from Częstochowa, more Jews were being brought in from nearby towns and villages including Krzepice, Olsztyn, Mstów, Janów, Przyrów, as well as hundreds of expellees from Polish lands annexed into the Reich at the beginning of war, mostly from Płock and Łódź. The ghetto inhabitants were forced to work as slave labor in the armaments industry, majority in the expanded Polish foundry "Metalurgia" located on Krotka Street (which had been taken over by the German manufacturer HASAG), as well as in other local factories or workshops.

Karsten Troyke (born Karsten Bertolt Sellhorn on 14 August 1960 in Berlin) is a German singer, actor, and speaker. He is best known as an interpreter of Yiddish song.

Performing on stage since 1982, Troyke had earlier worked as a gardener and with mentally handicapped children. He studied singing (with Leonore Gendries) as well as drama and speaking, and in 1990 he gave up his work to dedicate himself completely to musical performance and theater. Troyke participated in radio plays, worked as a voice actor (dubbing), and participated in various stage plays.

As a singer, his album Yiddish Anders (1992) received the praise of German record critics. Jidische Vergessene Lieder (1997) contained previously unpublished songs of Sara Bialas Tenenberg, who became his mentor for the Yiddish language.

In his performances Troyke worked with Bettina Wegner, Suzanna and the Trio Scho. His interpretations of the songs of Georg Kreisler received mention in the writer/musician's 2005 biography. In 2006 two documentaries, Yiddish Soul and Concert Yiddish Soul, featured Troyke, Shura Lipovsky, Myriam Fuks and The KlezRoym.
