The major battles of romanticism in France were in the theater. The early years of the century were marked by a revival of classicism and classical-inspired tragedies, often with themes of national sacrifice or patriotic heroism in keeping with the spirit of the Revolution, but the production of Victor Hugo's "Hernani" in 1830 marked the triumph of the romantic movement on the stage (a description of the turbulent opening night can be found in Théophile Gautier). The dramatic unities of time and place were abolished, tragic and comic elements appeared together and metrical freedom was won. Marked by the plays of Friedrich Schiller, the romantics often chose subjects from historic periods (the French Renaissance, the reign of Louis XIII of France) and doomed noble characters (rebel princes and outlaws) or misunderstood artists (Vigny's play based on the life of Thomas Chatterton).
