"Galeazzo Maria Sforza (24 January 1444 – 26 December 1476) was the fifth Duke of Milan from 1466 until his assassination a decade later. He was notorious for being lustful, cruel and tyrannical.
He was born to Francesco Sforza, a popular condottiero and ally of Cosimo de´ Medici who would gain the Duchy of Milan in 1450, and Bianca Maria Visconti. He married into the Gonzaga family; on the death of his first wife Dorotea Gonzaga, he married Bona of Savoy." - (en.wikipedia.org 17.11.2019)
