From their obscure origins as soldiers of fortune they established themselves as a princely house and one of the leading powers of Italy. Among those noted for their cultivation of the arts were Francesco Sforza (1401-1466) and his son Lodovico Sforza (1451-1508), both Dukes of Milan. It was Lodovico who gained further prominence through the employment of Leonardo da Vinci. A comprehensive history derived from early sources.
