Rudolf, Crown Prince of Austria, was the only son and third child of Emperor Franz Joseph I and Elisabeth of Bavaria. He was heir apparent to the Imperial throne of the Austro-Hungarian Empire from birth. In 1889, he died in a suicide pact with his mistress, Mary Freiin von Vetsera, at the Mayerling hunting lodge. The ensuing scandal made international headlines. He was named after the first Habsburg King of Germany, Rudolf I, who reigned from 1273 to 1291.
