In the Second Polish Republic, Dukla belonged to Krosno County of Lwów Voivodeship. In the spring of 1939, Border Protection Corps Battalion Dukla was formed, to protect Polish - Slovakian border. German occupation spelled the end of Jewish presence in the town, which dated back hundreds of years. In prewar Dukla, Jews were in the majority. Germans opened here a ghetto, which was liquidated on August 13, 1942, when some 500 Jews were shot near the village of Tylawa. In 1940, the 1758 synagogue was burned.
