- Taxes and economic issues: The Visigoths under Alaric I had been settled in the Balkans, where they were allied with Rome and helped to defend the border against other tribes. However, they complained that they were burdened with heavy taxes and not given enough land or supplies to support themselves.
- Political tensions: Alaric and the Visigoths were frustrated with the political instability and internal conflicts within the Roman Empire. They felt that they were not treated as equals by the Romans and that their concerns were not being addressed.
- Military conflicts: The Visigoths clashed with Roman troops on several occasions, further escalating tensions between the two groups.
- Alaric's ambition: Alaric was a charismatic and ambitious leader who saw an opportunity to gain power and wealth by leading his people against Rome. He aimed to secure better lands for his followers and to establish an independent kingdom.
In summary, the Visigoths rebelled against Rome due to a combination of economic grievances, political tensions, military conflicts, and Alaric's personal ambitions.
