Christopher Columbus may have been Spanish and Jewish, documentary says

Claim raises idea explorer was from community expelled by his Spanish patrons, but experts view it with caution

A 20-year genetic investigation of the remains of Christopher Columbus has turned conventional historical wisdom on its head by concluding that the explorer whose voyage to the New World changed the course of global history may have been a Spanish Jew rather than a son of Genoa.

The claim raises the intriguing prospect that the man who played a central part in the creation of Spain's mighty empire hailed from the very community that his patrons, King Ferdinand and Queen Isabella, expelled from their kingdom in the same year Columbus reached the Americas.
