MrT said:It's possible, however the general consensus of historians would not support that assertion. Most primary sources -- including Columbus' own writings -- identify him as being Genoese.
Given enough time, one can find internet sources to support almost any argument. Such sources are often of highly dubious credibility. A review of half a dozen credible sources strongly supports his Genoese birth as being most likely.
Noted historian Norman Davies calls him a "Genoese sailor" in his Europe: A History
The Encyclopaedia Britannica (known for being a reasonably accurate citation) identifies him as being " born between August 26 and October 31, 1451, Genoa [Italy]".
Most other credible secondary and tertiary sources concur. Some also mention the theory that he could be Portugese by birth, but most note that this is highly improbable.
I'm not suggesting that he was Spanish. I believe it highly likely that he was born Genoese (Tunch Khan's post is very interesting as to where in Genoese territory he originated), spent some period of time in his early adulthood in Portugal, and then became an agent of Spain for the remainder of his life (including the period during whch he made his voyages to the west).
Well, I support the portuguese theory (i'm portuguese and with the evidences that I've see). But everything in that time could be dubious. And exists theories about who discovered America that could be the Vikings, the Chinese, or the Portuguese.
