Cristóbal Colón aka Cristóvão Colombo aka Cristoforo Colombo aka Christopher Columbus has gotten lots of breaks from history. He escapes blame for the massive die-off of the peoples in this hemisphere on the theory he did not intend the spread of disease, but he also gets a pass on his barbaric personal conduct among the Taino people.
The exploration package he finally sold to the monarchs of what would be Spain (after failing to interest Portugal, England, Venice, and even his hometown of Genoa) involved making him governor of the lands he discovered and conjuring up a new title just for him. He had requested “Great Admiral of the Ocean” but he settled for “Admiral of the Ocean Sea.”
Note that Columbus was Genoan rather than Italian because Italy did not exist. From the fall of the Roman Empire to the middle of the 19th century, the peninsula was a land of warring and conspiring city-states. It was culturally rich but politically fragmented, like the Indians of North America.
Of course, there was no “Spain” either, but the marriage of Isabella I of Castile and Ferdinand II of Aragon laid the geographical and political basis for a nation that would become an empire based on looting of the Americas by the conquistadores who followed Columbus. The miscalculation of the monarchs who turned down Columbus would be unmatched in history until Decca Records turned down The Beatles, but of course the Fab Four were not thieves.
