Religion was also important to many Czechs. The majority of Czechs had been nominal Catholics in their homeland, loyalty to the church was often associated with the oppressive Hapsburg monarchy that had persecuted native Czech Protestants after defeating their forces at the decisive 1620 Battle of White Mountain.  The Czech Freethought movement was fairly popular during the late 19th century, which was brought by many Czechs to the United States during their migration. Despite most of the Czechs in Oklahoma being associated with Freethought, there were still many that believed in Catholicism. Although they were in a minority, Oklahoma Czech Catholics founded some distinctive and enduring parishes, including St. Wenceslaus in Prague (1891), St. John Nepomuk in Yukon (1894), St. Martin's in Mishak (1905), and St. John in Bison (1909). 
After all of this influence that Czechs have had on the community of Yukon and the state of Oklahoma, there were only two ways to honor this ethnic group - the Prague Kolache Festival and the Oklahoma Czech Festival held in Yukon. The Oklahoma Czech Festival had its beginning in October 1966, when the lodges of Yukon Czech Hall, WFLA Lodge #67 and Sokol Lodge Karel Havlicek, sponsored a festival to celebrate the City of Yukon’s 75th anniversary.  This reunion marked the beginning of a yearly tradition that celebrates every member of the Czech community. This tradition has been going steady for over 50 years. The goal and purpose of the Oklahoma Czech Festival is the preservation and sharing of the old Czech customs so dear to the people of Czech descent. These customs, including recipes, kroje, songs, and dances, have been handed down from generation to generation.  The Oklahoma Czech Festival is one of the most unique experiences one can imagine. Should someone find themselves near Yukon on the first weekend of October, they should definitely make the trip to experience this celebratory occasion.
