Karlsruhe was named after the German city of Karlsruhe by Germans from Russia. Karlsruhe was first settled in the late 19th century by German pioneers moving toward northern American prairie lands. These pioneers and their early generations of relatives are buried in the St. Peter and Paul cemetery. In the town's early years, many German traditions were practiced regularly, however, throughout the years it has become an Americanized town, with very few of these traditions still present. Karlsruhe's population has continued to decrease to this day.
