Once upon a time in the town of Urbino, Italy, there lived a man named Federico da Montefeltro, the Duke of Urbino. By profession, he was a condottiere—a soldier for hire who led recruits from his hometown into battle on behalf of well-to-do clients, including the city of Florence and the pope, who in those days had his own army. Federico was a clever strategist and an effective leader, and he usually won his battles. Over the years, he and his men were much in demand and well compensated for their efforts, and little Urbino became a prosperous center of culture and the arts.
