The Great Romance (1919)

King Rudolph of Rugaria sends his son, Prince Boris, to America to marry into wealth so that the country can recover from its financial difficulties. Rich Mrs. Hanway, eager to have her daughter Althea become a princess, takes her with Boris to Rugaria. Meanwhile, Rupert Danza, a Columbia University student, is told by a mysterious envoy that he is needed in Rugaria to lead a revolution. Although he laughs at first, he follows, when he learns that his sweetheart Althea has gone there. While Rupert's knowledge of democracy inspires the revolutionaries, his sword play enables him to rescue Althea from Boris. After an anarchist wounds the king, Rupert is arrested, but as a firing squad prepares to execute him, Countess Olga reveals that he is really the king's son who was kidnapped as a child and sent to America to absorb democracy for the coming revolution. After Rudolph dies, Rupert declines the crown, but is elected president of the newly-created republic. Althea then becomes his First Lady.
