The Spanish Tragedy was written in the late 1580s, likely by Thomas Kyd. It was highly influential, spawning many revenge tragedies. The play is set in a corrupt Spanish court and explores themes of revenge, justice, and the conflict between divine and human justice. It leaves ambiguous how Don Andrea was killed and whether the characters can find justice through legal or divine means, as revenge continues to drive the plot. The play helped establish conventions for the new revenge tragedy genre in Elizabethan theatre.
