Fleeing political unrest in their homeland, Germans began arriving in Detroit during the 1830's. Lured by state of Michigan recruiting pamphlets, German musicians, teachers and professionals joined increasing numbers of immigrants in Detroit. By 1880, twenty percent of the city's population was German-born. Most of these immigrants settled in this area, known as Germantown, between the Jefferson and Gratiot Avenue corridors. Many opened shops and businesses ranging from breweries to tailoring shops to tanneries. Harmonie Park, its name associated with the nearby Harmonie Club, was as important center of Germantown. Greek immigrants moved into a part of Germantown that later became known as Greektown.
