Jozef Mlot-Mroz

Jozef Mlot-Mroz (born Józef Wladyslaw Mróz; January 21, 1921 – October 31, 2002) was a Polish-American anti-communist, right-wing political activist and antisemitic conspiracy theorist.

During the Second World War, Mroz fought with the Polish Home Army against the German occupation of Poland, and after the war ended he continued to participate in subversive activities against communist authorities, for which he was imprisoned. After escaping Soviet captivity he fled to Germany and eventually immigrated to the United States, where he became a prolific anti-Communist protester and opponent of the civil rights movement known for his inflammatory protest signs and provocative activity.

A political conservative, Mroz opposed racial integration and abortion rights, and supported American involvement in the Vietnam War. His political positions were tied to his belief in antisemitic and white supremacist conspiracy theories, and shortly before his death it was revealed that the frequency of his activism was made possible by donations from wealthy far-right patrons.

He attended public grammar school in Jedlicze, and high school and college in Krosno.

In 1940, during the occupation of Poland by Nazi Germany, he was imprisoned by the German Gestapo for 3 months, and upon being released joined the Underground resistance movement. In 1945 he was imprisoned for 21 months by Soviet authorities for participation in the Polish Underground, and after his release he became secretary of an air club in Krosno.
