More than one and a half thousand years ago, Rome was the capital of a huge empire. For centuries, the Romans crushed their opponents. They were proud to rule over hundreds of peoples and tribes. No wonder Rome was called the Eternal City. Its inhabitants were accustomed to military festivities, to processions of troops, to the sight of looted booty. But you cannot dominate the world forever. Years passed: Rome weakened in constant wars, while the number of its enemies increased. The German tribes that annoyed Rome more than others. They invaded his possessions, and neither the rivers, wide and deep, nor the fortifications along the banks, nor even the detachments of troops guarding the border day and night, were an obstacle for them. This book is about how the once powerful Roman Empire ended its existence.
