Duchy of Saxe-Altenburg
The township was organized in 1821, and Brazeau Township was one of the three original townships in Perry County, Missouri, with the other two townships being Bois Brule and Cinque Hommes. Soon thereafter, Protestant English and Scots-Irish settlers arrived from North Carolina. In 1839, German Lutheran immigrants from the Duchy of Saxe-Altenburg arrived and established 6 "colonies" in the township: Altenburg, Dresden, Frohna, Johannisberg, Seelitz, and Wittenberg. The seventh colony, Paitzdorf (Uniontown, Missouri), lies in Union Township
