Pierre Corneille's Le Cid was first performed in 1637 and became a sensation in Paris. Its success provoked debate over dramatic rules, probability, morality and classical decorum. The quarrel revealed the growing authority of critics and institutions over theatre.

The dispute around Le Cid helped define French neoclassical drama and the prestige of formal rules. It shaped the stage world inherited by Racine and Molière, where poetic brilliance had to negotiate taste, patronage and doctrine.
