Between World War I and World War II, Zdzięcioł (now Dziatlava) belonged to the eastern part of the Second Polish Republic. It was the seat of Gmina Zdzięcioł in Nowogródek Voivodeship. The population was composed predominantly of Polish Jews. The Soviet forces invaded eastern Poland on September 17, 1939, and stationed in the Voivodeship area until the outbreak of their own war with Germany in June 1941. After the Soviet rapid retreat, and several months of Nazi ad hoc persecution, on February 22, 1942 the new German authorities officially created Zdzięcioł Ghetto.
