First appearance: persons of the dialogue

As a major figure in The Republic, Polemarchus is not background color—the story leans on what they do once the chapter opens.

Intercepts Socrates and Glaucon, compelling them to his house; initially defends his father's definition of justice.

Polemarchus is the young man whose playful ambush—'are you stronger than all these?'—drags Socrates and Glaucon into his father's house and sets the whole dialogue in motion. He inherits the old proverb that justice means helping friends and harming enemies, and defends it with the confidence of a man raised on poetry and tradition. His quick defeat by Socrates clears the ground for the more dangerous challenge of Thrasymachus.
