The Marcomannic Wars shocked the very foundations of the roman empire in the second half of the 2nd century AD Historia Augusta recounts the turmoil caused by the barbarians at Rome’s boundaries: „...Victualis et Marcomannis cuncta turbantibus, aliis etiam gentibus,
quae pulsae a superioribus barbaris fugerant, nisi reciperentur, bellum inferentibus”. The barbarians of the middle Danube were rocked by the goths, the impact of this movement being strongly felt by the barbarians on the Danube border, and in short time, by the roman border itself. The instability occurred when the Marcomanni, Quadi and Iazyges took the initiative in the war against Rome. The Marcomannic Wars had a great impact on the evolution of the middle and lower Danube regions, as well as Rome itself. The imperial effort dried out the state resources, and in the roman army, it caused a phenomenon that will be felt especially in the 3rd and 4th centuries - the barbarization of the roman armies.
