The second scene of the act takes place in a square in Madrid. An auto-da-fé is being prepared. During the time of the Spanish Inquisition this was a ceremony in which anyone who did not agree with the Roman Catholic church was burnt to death. Monks enter, followed by the unfortunate people who are going to be burnt. The people sing about the glories of Spain. King Philippe appears and repeats how he will fight against anyone who is an enemy of the Roman Catholic Church. Six people, including Carlos, appear and fling themselves at his feet, begging him to stop his troops from killing the Flemish people. The King will not hear of it. Some of the crowd support the king, but others are begging him to have mercy. Carlos then asks his father to allow him to rule Flanders for him. The King does not allow this, because he realizes that this could be an opportunity for Carlos and the Flemish people to rise against him. Carlos is desperate. He draws his sword and says that he will save Flanders. The crowd are terrified to see him behave like this in front of the King. The King commands his soldiers to take the sword away from Carlos, but no one obeys him. In the end, Rodrigue (who realizes that this is going to be bad for him) saves the situation by calmly asking Carlos for the sword. He hands it over and Rodrigue gives it to the King. The monks process farther, and a voice from heaven promises peace in the world to come.
