Moravia is home to one of the oldest Protestant denominations in the world. Moravia was also home to the Hussite movement, founded and led by Jan Hus in early 15th century Bohemia. Additionally, Moravia is home to a pilgrimage of Saint Anthony. Deep religious culture and tradition saturated life in Moravia and Uprka worked to immortalize it in his work. This immortalization is pertinent to remembering religious tradition and devotion preceding the takeover of the Soviets. 

Uprka’s artworks depicted the interior of church scenes, pious girls and women, and everyday devotees of the Christian church. His depictions provide insight into clothing associated with worship, often utilizing the color white with both men and women.
