Francesco Uguccione (or François Hugotion de Aguzzoni) (died 14 July 1412[1]) was the Archbishop of Bordeaux from 1384 until his death.
In spring and summer of that year he began a long string of desperate letters to the English king, Henry Bolingbroke.
He implored His Majesty for aid and assured him of the gravity of the situation, including the death of the lord of Mussidan, a Gascon loyal to the English, who had been commanding the fortress at Blaye and had left only a daughter.
On 30 June, he wrote: "I have written to you so many times and so lengthily concerning the state of your land, and I have cried so much that my voice has become hoarse.
In Autumn 1408 he went to England, where he sought to persuade the English as per the summons of the College of Cardinals to send a delegation to the Council of Pisa then struggling to put an end to the Western Schism.
