Drama originated in ancient Greece between 600-200 BC as a form of religious worship to Dionysus. It began as religious chants and songs performed by a chorus and gradually incorporated additional actors and dialogue. During the Elizabethan era in 16th-17th century England, playwrights like Shakespeare and Marlowe flourished. Shakespeare initially wrote in conventional styles but later adapted them to be more natural. Drama can be categorized as opera, pantomime, or creative drama and takes forms like comedy, tragedy, farce, and musical drama. It uses elements like theme, plot, effects, and music.
