One of the fascinating figures in Polish history is Bona Sforza, as one might tell, not a Polish lady but an Italian one who by marriage became Queen of Poland and Grand Duchess of Lithuania and a consort that had quite an impact. Those familiar with the tumultuous political history of Renaissance Italy will recognize the Sforza family name, a powerhouse in Milan and a long-time force in Italian politics. As the rulers of Milan the Sforza family had at one time or another Lord Jean I of Monaco and Leonardo da Vinci and eventually had marriage times with numerous royal and papal families. Bona Sforza was born on February 2, 1494 the third child out of four of Gian Galeazzo Sforza (sixth Duke of Milan) and his wife Isabella of Naples (daughter of King Alfonso II) -thought by some to be the inspiration for the Mona Lisa. The real power at the time though was her great uncle Ludovico Sforza, a patron of the arts and Renaissance man responsible for starting the Italian Wars and who later got himself into a great deal of trouble with the King of France for trying to assassinate Jean II of Monaco. Despite such powerful family ties, Bona Sforza had a rather tragic youth, being the only one of her siblings to survive childhood.
