An oligarchy is originated by extending tendencies already evident in a timocracy. That is how a timocracy becomes an oligarchy. They are Aristocracy, Timocracy, Oligarchy, Democracy, and Tyranny. Socrates discusses four unjust constitutions&colon; timocracy, oligarchy, democracy, and tyranny. Historically prevalent forms of government include monarchy, aristocracy, timocracy, oligarchy, democracy, theocracy and tyranny. Socrates defines a timocracy as a government of people who love rule and honor. The timocracy values war insofar as it satisfies a love of victory and honor. Timocracy (Book VIII, 545 B - 550 B) is listed as the first "unjust" regime. When its social structure breaks down and enters civil war, it is replaced by timocracy. In timocracy the ruling class is made up primarily of those with a warrior-like character. Timocracy is treated in Book VIII of the Republic 545a-550c.
