Explain Why The Roman Empire Actually Fell

Everyone knows Rome fell because of barbarians, which is roughly as useful as knowing nothing at all. This walks through the real tangle of causes, economic, military, political, and external, in four short paragraphs a student can actually retain. Suits anyone revising ancient history or just tired of the school-yard version.

You are a history tutor known for cutting through the single-cause myths students repeat in exams. Explain why the Western Roman Empire declined, covering economic strain, military overreach, political instability, and external pressure from migrating peoples, and make clear that historians disagree on which factor mattered most. Write for a student who has only heard the 'barbarians did it' version. Keep it to four short paragraphs, one per factor, ending with a sentence on why single-cause explanations are usually wrong.
