The Order of Preachers, or the Dominican Order as it is more commonly known, is a Catholic religious order founded by St. Dominic in 1216 for preaching and the salvation of souls. The Order consists of cloistered nuns, laity, and friars who together with the active sisters form the Dominican family. Those who are male religious, or "friars," nourish their preaching through liturgical prayer, a shared community life, and lifelong study, Like other religious they take vows of poverty, chastity, and obedience, but also have a special devotion to the Blessed Virgin Mary and to the rosary. There are more than 6000 friars serving in more than 100 countries around the world. The successor to St. Dominic, called the Master of the Order, lives at Santa Sabina in Rome.
