Wiarus (Veteran Defender) was the name of a Polish-language newspaper published in Winona, Minnesota from 1886 to 1893 and 1895 to 1919; in 1893 it was renamed Katolik, but reverted to its original name in 1895. Although Winona's Polish community was known at the time as the "Kashubian Capital of America," Wiarus was published in the "good" Polish spoken in Warsaw and Krakow. Wiarus also provided printing services for Winona's Kashubian Polish community. From 1886 to 1902, Wiarus was edited by the famed Kashubian-born poet and journalist Hieronim Derdowski. In its heyday, Wiarus was said to be the most widely circulated Polish-language newspaper in the United States.
