The Lord of Milan was a medieval noble title for the dynastic head of state of the city of Milan and surrounding countryside in northern Italy. From 1277 to 1395, the Visconti family held the title, after which they were elevated to Duke of Milan.
Until 1259, Milan was a free commune that elected its own podestà. The Torriani family gained sustained power in 1240, when was elected podestà.[1] After Pagano's death, Baldo Ghiringhelli was elected podestà in 1259, but at the end of his tenure Martino della Torre, Pagano's nephew, perpetrated a coup d'état, seizing power for his family and establishing the first Signoria ('Lordship') of Milan.[2]

During their tenure, the Torriani family, aligned with the French Charles of Anjou (the Guelph faction), began a strong rivalry with the Visconti family, who were aligned with the German Hohenstaufen (the Ghibelline faction).[3] In 1262, Pope Urban IV appointed Ottone Visconti as Archbishop of Milan, to Martino della Torre's disappointment.[4] In 1273, a civil war started between the two families, ending with the Torriani's defeat in the Battle of Desio of 1277, which the Visconti subsequently commemorated with frescoes in the Castle of Angera.[5]

In June 1302, Guido della Torre forged a coalition with anti-Visconti cities and marched on Milan, deposing the Visconti.[6] However, in 1308 Guido quarrelled with his cousin, the Archbishop Cassone della Torre. After an assault on Milan Cathedral, Cassone fled to Bologna and solicited an imperial intervention.[7] Taking advantage of a chaotic situation in Northern Italy, King Henry VII of Germany invaded Italy, and in Autumn 1310 he marched on Milan to restore both Cassone and the Visconti. After the fall of Milan, he was crowned King of Italy in the city's Cathedral.[8]
