Gian Galeazzo Sforza II

Gian Galeazzo Sforza II was the son of Galeazzo Maria Sforza and succeeded him as duke of Milan. His reign was brief and troubled, as his power was soon usurped by his uncle, Ludovico the Moor. Ludovico Sforza, also known as "il Moro," was the second son of Francesco Sforza, who had established the Sforza dynasty in Milan. Francesco Sforza, a condottiere, became duke of Milan in 1450. Ludovico, after his father's death and his brother Galeazzo Maria's murder, plotted to gain power, eventually becoming regent for his nephew, Gian Galeazzo, and later assuming the title of duke of Milan.123
