During World War II many families in the village hid their Jewish neighbours to help them survive the Holocaust. It is now estimated that at least 17 Jews survived the war in Markowa.
Grave monument of Ulma family executed in 1944
Seven members of the Weltz family were hidden in the barn of Dorota and Antoni Szylar. Jakub Einhorn's family was hidden by Jan and Weronika Przybylak and Jakub Lorbenfeld and his family were hidden by Michal Bar. Two girls from the Riesenbach family were initially hidden by Stanislaw Kielar, before joining the other three family members in the attic of Julia and Józef Bar.
On March 24, 1944 a patrol of German police came to the house of Józef and Wiktoria Ulma, where they found eight Jews belonging to the Szall and Goldman families. At first the Germans executed all the Jews. Then they shot the pregnant Wiktoria and her husband. When the six children began to scream at the sight of their parents' bodies, Joseph Kokott, a German police officer (Volksdeutsche from Sudetenland), shot them after consulting with his superior. The other killers were Eilert Dieken, Michael Dziewulski and Erich Wilde.
On the 60th anniversary of this tragedy, a memorial was erected in memory of the family.
