Paitzdorf was first mentioned in writing in 1290.

In 1837, around 140 Paitzdorfers left for America, seeking religious freedom. Along with immigrants from Saxony, they founded the communities of Altenburg, Frohna, Wittenberg, Dresden, and Paitzdorf on the Mississippi River in Missouri. This group would later found the Lutheran Church–Missouri Synod.

In 1963, Paitzdorf's windmill, erected in 1792, was torn down.
