June 29

The Słonim Ghetto was the site of the rapid persecution, ghettoization, mass shootings, and final liquidation of the Jewish community of Słonim (then in the Byelorussian SSR) following the German invasion that began on June 22, 1941. Over the late summer and autumn of 1941 and through 1942, Einsatzgruppen, Ordnungspolizei units, and local auxiliaries carried out organized roundups and mass executions—most notably a series of large shootings in mid‑November 1941—that destroyed the large prewar Jewish presence in Słonim and the surrounding district. Estimates of victims vary by whether they count town residents alone or include the wider county; scholarly and memorial figures commonly range from several thousand into the low tens of thousands.
