Trappist monks come from the Order of Cistercians of the Strict Observance (OCSO), following the Rule of St. Benedict. They were founded in 1664 to counter the relaxation of practices in Cistercian monasteries in France. Because they are contemplative, the Trappists lead a life of prayer and penance. They abstain from meat and observe silence at meals, during the night, and when practical during the day. Usually monasteries make and sell goods for income. Some Trappist-made beer is considered the finest in the world. There are over 170 Trappist monasteries in the world that house some 2500 monks and 1800 Trappistine nuns.
