Plato's Republic is often considered the first work of political philosophy ever written. Plato was also the first guy to imagine a fictional city as a way to think about ideal forms of government and social structure (this model later was turned into the utopian genre by Thomas More).
But just because Plato's Republic is a classic of political philosophy, that doesn't mean it wasn't—or isn't—way controversial. Condemning democracy, championing aristocracy, and abolishing the family as a social unit, Plato's philosophy isn't everyone's cup of tea. Even if you don't agree with him, though, you've got to give it to him: he makes some interesting points, and he makes them well.

Plato's suspicion toward democracy is completely justified; he watched a democratic government execute his teacher Socrates.
Plato's conception of politics has a lot in common with issues we deal with today. He even condones lying in political situations if it "benefits" the public.
