Francesco I Sforza
On 7 January 1459 he was appointed as nuncio by Pope Pius II with support from Francesco I Sforza, Duke of Milan. Departing some weeks later, he gave the name to the "Coppini Mission" to England with the double purpose of bringing about an end to the Wars of the Roses, and persuading King Henry VI of England to join the crusade against the Turks. He was also given instructions to carry out in Burgundy, Cambrai and the Netherlands.
