Jean de Villiers was the twenty-second grand master of the Knights Hospitaller, serving from 1285 until 1293.[1] He was elected Grand Master after the death of Nicolas Lorgne. De Villiers was Prior of France beginning in 1282 and he remained in France to deal with existing problems of the Order. Jacques de Taxi became Grand Master ad interim, perhaps through 27 June 1286, while awaiting the arrival of the newly elected Grand Master in the Holy Land. De Villiers was present at the Siege of Acre in 1291, but escaped just before the city fell to the Mamluks. He was succeeded by Odon de Pins.[2]
