In page Francesco I Sforza:

"

Under his rule (which was moderate and skilful), Sforza modernised the city and duchy. He created an efficient system of taxation that generated enormous revenues for the government, his court became a centre of Renaissance learning and culture, and the people of Milan grew to love him. In Milan, he founded the Ospedale Maggiore, restored the Palazzo ducale, and had the Naviglio d'Adda, a channel connecting with the River Adda, built.[citation needed]
