Gnadenau was a communal village of German-speaking Mennonite immigrants from Russia in Marion County, Kansas, United States.

For many millennia, the Great Plains of North America was inhabited by nomadic Native Americans.

In 1803, most of the land for modern day Kansas was acquired by the United States from France as part of the 828,000 square mile Louisiana Purchase for 2.83 cents per acre.

In 1855, Marion County was established within the Kansas Territory, which included the land for modern day Gnadenau.

[3][4] Unlike the majority of Mennonites, this body adopted trine forward immersion as the mode of baptism.
