Jacopino da Carrara
Jacopino da Carrara, also called Giacomino, was a Paduan nobleman of the imperial party. Around 1163 he married the wealthy heiress Speronella Dalesmanni; when the emperor's vicar Pagano della Torre abducted her, her kinsmen besieged the fortress and in 1164 defeated Barbarossa's representative, an episode seen as the birth of Padua's free commune.
Jacopino nevertheless stayed loyal to the emperor, and in 1174 he became podestà of Treviso before dying at Padua around 1190.
