The late 1830s saw the beginnings of a heavy German immigration that would permanently alter the ethnic balance of the county. In the fall of 1838, more than 600 Saxon Lutherans, under the leadership of Pastor Martin Stephan, uprooted themselves and migrated to Missouri in what is called The Saxon Lutheran Migration, seeking to avoid the enforced religious conformity brought about by the Prussian Union of churches. They settled in the southeastern corner of the county and moved inland through a series of towns whose names enshrined both religion and nationality: Wittenberg, Friedheim, Frohna, Dresden, Altenburg, and Paitzdorf, which was renamed Uniontown during the American Civil War. Much of the legacy of the German immigration lives on today through the Lutheran Church–Missouri Synod. A distinct Saxon dialect of German continues to be spoken by about 250 residents (in 2014), although that number is declining with the youngest speakers being over 50 years old.
