A Prince of a King (1923)

In a fifteenth-century kingdom, Duke Roberto usurps the throne by poisoning King Lorenzo and abandoning the sole heir, Prince Gigi, in the wilderness. A troupe of Gypsy acrobats discover the infant prince, and their leader, Andrea, adopts him. Gigi becomes the troupe's star performer, but during a visit to the kingdom, he attempts to escape the abusive acrobats. The prince is recognized by the court physician and returned to the queen mother. Duke Roberto is punished for his crimes and the Gypsies are banished from the court.
