The history of Germany goes back to the Roman military campaigns in Germania and the the fall of the Roman Empire when the Germanic tribes poured into Western Europe from the East in the 4th and 5th centuries AD. Although its origin, as a political entity, begins with the Carolingian Empire and its successor durin, the Holy Roman Empire of the German Nation, it was a religious military order, the Teutonic Knights, the foundation stone of the kingdom that would unify the fragmented German states in the second half of the 19th century. The German states (duchies, principalities, and estates) had broken away from the Holy Roman Empire in the 16th century as a result of Martin Luther’s schism.
