This is a single enlisted man shoulder strap from 2. Nassauisches Infanterie-Regiment Nr 88. The regiment was founded in 1808. It was garrisoned at Mainz and Hanau, where it was attached to the XVIII. ArmeeKorps. The regiment originally belonged to Nassau. It was absorbed into the Prussian Army after the 1866 Austro-Prussian war. Several German states, including Hannover, Braunschweig, Nassau, and Hesse-Kassel fought on the Austrian side (along with Bavaria, Saxony, and Württemberg). They all were absorbed into Prussia after Germany’s final consolidation war. This war’s outcome cemented Prussia’s dominance. After the 1870/71 Franco-Prussian War, Prussia’s König Wilhelm I was crowned Kaiser Wilhelm I of all Germany. This regiment, along with her sister regiment 1. Nassauisches Infanterie-Regiment Nr 87, wore a special bandeau on its pickelhauben, which Kaiser Wilhelm II granted to them around 1897. The former Nassau, Hannover, and Braunschweig regiments all received these bandeaux acknowledging their Napoleonic War service. The shoulder strap is blue and sports a crowned red cypher for Nassau’s former ruler. The shoulder strap has no buttonhole and was never worn on a tunic. Some small moth nips appear around its edges. These are limited on the obverse, but a bit more frequent on the reverse.
