The 7 Laws of Empires: Why They Rise and Fall

Every empire that grows must eventually stretch its resources too thin. Rome, Mongols, Britain—all faced rebellion at the periphery and administrative chaos at the core. The very act of conquest sows the seeds of decline.

When a central authority becomes too distant from its provinces, local elites gain more autonomy. Over time, these centrifugal forces pull the empire apart. The Byzantine Empire survived for a millennium by devolving power, but eventually even that failed.

Empires that substitute money for loyalty often hire foreign mercenaries. These soldiers have no stake in the empire's survival. The Roman Empire's reliance on Germanic foederati was a key factor in its collapse.

Embracing diverse cultures can strengthen an empire, but it can also dilute its identity. The Persian Empire's tolerance was its strength, yet it also allowed for the rise of local identities that eventually sought independence.
