Christopher Columbus was an Italian explorer, navigator, and colonizer, born in the Republic of Genoa (today part of Italy). Under the auspices of the Catholic Monarchs of Spain, he completed four voyages across the Atlantic Ocean. Those voyages and his efforts to establish permanent settlements on the island of Hispaniola initiated the Spanish colonization of the New World. Therefore, becoming known as the first explorer to discover America and to prove that the world was in fact round rather than flat.
Although he never existed during the times of movies, his name was used in some Disney movies like Columbus Avenue in New York City which was named after him in Oliver & Company and the Donald Duck comic story; The Lost Charts of Columbus and the Goofy comic story; Christophorus Goofy Columbus where Goofy appeared as Christopher Columbus himself. He even made an animated appearance in the Disney 1948 movie, So Dear to My Heart when he was singing Stick-to-it-ivity. He also made a brief appearance with Leif Erikson in the Academy Award winning short, It's Tough to Be a Bird. The apocryphal tale of him discovering that the world wasn't flat would have also been the subject of a 1992 theatrical short called Mickey Columbus, which would have placed Mickey Mouse in the role of Columbus, until it was shelved both to help the studio focus on full-length animated features and in fear of potentially producing offensive Native American stereotypes. His name and that of his three historical ships: the Santa Maria, the Nina, and the Pinta along with a fictitious 4th one called the "Snookie" was mentioned by Daisy in the Quack Pack episode; "Pride Goeth Before the Fall Guy". Ohio's capital and largest city were also named after Christopher Columbus. A drawing of him has also seen in the Timon & Pumbaa episode; "Hakuna Matata U.". He has mentioned in the Wizards of Waverly Place episode Retest.
