The Iowa Classis Archives document the corporate institutional life of a regional classis of the Reformed Church in America based in Iowa in decades surrounding the turn of the 19th to the 20th century. The records include the minutes of the classis, church statistics, financial materials, and correspondence. Collectively, these archives provide evidence for the historical growth of a first- and second-generation Dutch-immigrant Protestant denomination in the trans-Mississippi prairies and northern plains over the span of thirty-four years.
