Why the Roman Republic Was Built to Destroy Itself

In 509 BC, Rome expelled its last king and built a system specifically designed to make sure no one man could ever hold absolute power again. Two consuls instead of one. Annual magistracies. A Senate to check the executives. Tribunes to check the Senate. Layer upon layer of mutual vetoes, each one designed to prevent tyranny. It worked for four hundred years. Then it produced Caesar, Augustus, and the end of the Republic it was supposed to protect. The problem wasn't that Romans stopped believing in the system. The problem was structural. The same features that prevented tyranny also prevented the Republic from resolving the land crisis, adapting to a larger empire, or stopping the cycle of escalation once it started. The Roman Republic wasn't destroyed by bad men. It was destroyed by good institutions that couldn't solve the problems they were never designed to solve.
