The League of Youth is a play by Henrik Ibsen finished in early May 1869. It was Ibsen's first play in colloquial prose and marks a turning point in his style towards realism and away from verse. It was widely considered Ibsen's most popular play in nineteenth-century Norway. Though rooted in serious events of the time, the play was lauded for its natural and witty dialogue, cynical humour and farcical intrigue.
