 Robert Kilwardby was an Englishman born either in Leicestershire or in Yorkshire, probably, in 1215. He started his university studies in Paris around 1231, becoming a Master of Arts around 1237. He taught there until 1245, when he moved back to England, at which time he entered into the Dominican Order. This marked the beginning of a rather successful ecclesiastic career. At Oxford (from ca. 1254 onwards), he studied and taught theology until 1261, when he was elected Prior Provincial of the English Dominicans. In 1269 he participated in the Dominican General Chapter in Paris where he, together with Thomas Aquinas (and other members), was responsible for analyzing the process of Bartholomew of Tours (MOPH I, 155). During this period he was also involved in a polemic about the nature of poverty with the Franciscans, after sending a letter on this topic to the novices of his Dominican Order. Kilwardby’s letter is now lost, so our knowledge of this dispute comes from a response by the Franciscan John Pecham, who rebuts Kilwardby’s claims, while citing extensively from the Dominican’s text. Pecham’s hostility towards Kilwardby would continue later on, when he accuses Kilwardby of stealing documents—the register and the records of the See and objects from the See of Canterbury—after Kilwardby’s departure from the See of Canterbury. Kilwardby was nominated Archbishop of Canterbury in 1272. Two of his acts as Archbishop were the coronation of Edward I, at Westminster Abbey, on the 19th of August 1274 and the issuing of the Prohibitions of Oxford on the 18th of March 1277 (see Silva 2012).
