Plato wrote The Republic to describe his vision of a Utopian society "ruled by the best.".

Explanation:

Plato was born in Athens in 427 BC, two years after the death of Pericles. He lived to his mature age during the decline of the Athenian empire after the defeat to Sparta in the Peloponnese war. He witnessed the rise to power of the "Tyranny Of The Thirty," a kind of oligarchic government that succeeded Athenian democracy.

In this politically troubled environment, the philosopher built his "perfect city", a utopia foreseen in his main work: "The Republic", as an instrument capable of guiding a stable society that tends to perfection. In this sense, Plato proposes to replace the plutocracy that reigned in imperial Athens with a society governed by the best men of his time, in terms of knowledge and wisdom.
