Around 233 AD troops and portions of troops were withdrawn from the Upper German Limes and dispatched to the east of the Roman Empire, to fight against the Persian Sassanids. The weakening of the frontier's defence led to Germanic attacks, known as the "Alamanni attacks".

Archaeologically, burnt layers in villas, civil settlements and many forts can be proven, for example in numerus fort Miltenberg-Bürgstadt and in Seligenstadt. Hidden treasures from this time, valuables or coins that were hurriedly hidden, have been found in Kleinheubach and other sites.

The attacks ended under Maximinus Thrax (235-238 AD) when he crossed the Rhein from Mainz and pushed far into enemy territory. The Victoria column is probably related to this victory over the Germanic tribes.
