Quick Summary

The Duchy of Milan was a historical state in northern Italy. Its history is marked by feudal and dynastic conflicts, with powerful families like the della Torre and Visconti vying for control. The Visconti family eventually established a signoria, with Gian Galeazzo Visconti becoming the first duke in 1395.1

Following the Visconti, the Sforza family founded a new dynasty in 1450, ushering in a period of prosperity and cultural flourishing during the Italian Renaissance. However, the duchy frequently changed hands, falling under French and then Spanish rule. It later passed to Austrian control in 1706.12

Milan became the capital of Napoleon's Kingdom of Italy in 1805 before returning to Austrian rule after Napoleon's fall. The city played a significant role in the Italian unification movement, the Risorgimento, and after 1859, it became an integral part of the unified Italian state, developing into Italy's industrial and financial center.23
