自由劇場
Naturalism, a theatrical movement born out of Charles Darwin's "The Origin of Species" (1859) and contemporary political and economic conditions, found its main proponent in Émile Zola. The realisation of Zola's ideas was hindered by a lack of capable dramatists writing naturalist drama. André Antoine emerged in the 1880s with his "Théâtre Libre" that was only open to members and therefore was exempt from censorship. He quickly won the approval of Zola and began to stage Naturalistic works and other foreign realistic pieces.
