“The decline of Rome was the natural and inevitable effect of immoderate greatness.”Edward Gibbon · The History of the Decline and Fall of the Roman Empire · 1776
Empires rarely fall in one blow; they erode slowly from within until a single external shock brings them down.
Gibbon analyzed hundreds of years of Roman history and showed the decline came gradually, not suddenly. The army grew expensive to maintain, leaders changed too often, and the borders became harder to defend. Outside attacks were, in fact, the final step of a much older internal weakness.
Gibbon noticed that empires do not fall because of enemies, but because of their own weight. A company that grows too large can begin to wobble the same way. Offices fill with people who only approve papers. Money goes to useless salaries, not innovation. Over time, even a small external crisis can topple everything. The next step is to see how weak leaders speed up this process.
Why it matters Modern historians often compare today's great powers to Rome, using this same pattern of slow decline.
