Martino della Torre in the context of "Lord of Milan"

The Lordship of Milan was a state in Northern Italy created in May 1259 following the election of Martino della Torre as lord of Milan. From 1259 to 1277 it was governed by the Della Torre family until, following the Battle of Desio, Napo della Torre was forced to yield his position to Ottone Visconti. The domination of the Visconti dynasty led to a series of territorial conquests that led the family to achieve the title of Dukes of Milan in 1395.
