Don Carlos, Infante of Spain is Friedrich Schiller's historical play based on the life of the King of Spain. There are five main characters and eight minor.

Don Carlos

Philip the Second

Philip the Second is the King of Spain, the most powerful monarch in Europe. He has no love, only self-interest, and he is jealous, insecure, and easily fooled.


The Marquis de Posa, or Roderigo, is a friend of Don Carlos's. He swore loyalty to Carlos and is a superb soldier, confidant, thoughtful, and secretly a member of a religious order.
