Christoph Kolumbus oder Die Entdeckung Amerikas (1970)

Christopher Columbus's crazy idea of traveling to India can only be realized because the Spanish treasury is empty and Queen Isabella, who rules the country, is charmed by the charming, profit-seeking son of a poor weaver. With the ulterior motive of becoming the ruler of new lands and at the same time being able to polish up the ailing finances a little, Isabella commissions the navigator Columbus to set sail for the Spanish crown.
