William of Modena, also known as William of Sabina, Guglielmo de Chartreaux, Guglielmo de Savoy, Guillelmus, was an Italian clergyman and papal diplomat. He was frequently appointed a legate, or papal ambassador by the popes Honorius III and Gregory IX, especially in Livonia in the 1220s and in the Prussian questions of the 1240s. Eventually he resigned his see to devote himself to these diplomatic issues. On 28 May 1244 he was created Cardinal-Bishop of Sabina by Pope Innocent IV. For a short time (1219–1222) he served also as Vice-Chancellor of the Holy Roman Church.

Old Prussians, Baltic Prussians or simply Prussians were a Baltic people that inhabited the region of Prussia, on the southeastern shore of the Baltic Sea between the Vistula Lagoon to the west and the Curonian Lagoon to the east. As Balts, they spoke an Indo-European language of the Baltic branch now known as Old Prussian and worshipped pre-Christian deities. Their ethnonym was later adopted by predominantly Low German-speaking inhabitants of the region.
