Galdino della Sala was a 12th-century cardinal and Archbishop of Milan who played a significant role in the religious and political conflicts of his era. Born into a minor noble family in Milan around 1096, he rose through the ecclesiastical ranks to become a key ally of Pope Alexander III. He was a prominent figure during the schism involving the Antipope Victor IV, supporting the legitimate papacy against the interests of Holy Roman Emperor Frederick I Barbarossa. He died in 1176 while delivering a sermon.
