The Roman Empire's strength lay in its ability to incorporate diverse peoples, which was lost as it resisted integrating the Goths.

Rome's success can be attributed to its ability to integrate conquered peoples and ideas, often granting them a degree of Roman citizenship.

The Roman military was a massive force of half a million people, integrating foreigners and turning them into Romans over time.

The Romans focused on flexibility in their military organization, allowing them to adapt and overcome traditional heavy infantry tactics used by their enemies.

The Romans would often take the sons of conquered tribal leaders, raise them as Romans, and incorporate them into their society, turning enemies into allies. As early as the second century AD, Roman emperors and senators began to come from provinces like Spain and North Africa, rather than just Italy.

The Roman Empire's vast size made effective governance challenging, leading to slow communication and a natural fragmentation of power.

During the late Republic, the Roman army primarily consisted of indigenous Italians, with the expansion of auxiliaries occurring later in the empire.

The fall of the Roman Empire can be attributed to a combination of civil wars, migrations, and the inability to maintain military strength beyond its borders.

The Romans were exceptional engineers, known for their monumental buildings and road construction, which they took great pride in maintaining.
