Cardinal Richelieu is a 1935 American historical film directed by Rowland V. Lee and starring George Arliss, Maureen O'Sullivan, Edward Arnold and Cesar Romero.

In 1630, a group representing the feudal lords of France ask the pope for help in their fight against King Louis XIII's minister, the Cardinal Armand Jean du Plessis, Duc de Richelieu, who has prepared an edict to strip them of their lands.

Count Baradas, the leader of the group, convinces the queen mother to visit the king at his palace in the Louvre to demand Richelieu's dismissal.

Back at his palace, Richelieu learns that his ward Lenore, who has recently left a nearby convent, has fallen in love with Andre de Pons, whom she has met only once.

Realizing that he has just signed a death warrant against Andre, a Huguenot, for conspiring to incite the lords to resist the edict, Richelieu agrees to see him.

Baradas reveals that the queen mother is taking a secret treaty to the Spanish forces, and Andre agrees to assassinate Richelieu.
