The Poor Clares, officially the Order of Saint Clare (Ordo sanctae Clarae), originally referred to as the Order of Poor Ladies, and also known as the Clarisses or Clarissines, the Minoresses, the Franciscan Clarist Order, and the Second Order of Saint Francis, are members of a contemplative Order of nuns in the Catholic Church. The Poor Clares were the second Franciscan branch of the order to be established. Founded by Clare of Assisi and Francis of Assisi on Palm Sunday in the year 1212, they were organized after the Order of Friars Minor (the first Order), and before the Third Order of Saint Francis for the laity. As of 2011, there were over 20,000 Poor Clare nuns in over 75 countries throughout the world. They follow several different observances and are organized into federations. The Poor Clares follow the Rule of St. Clare, which was approved by Pope Innocent IV on the day before Clare's death in 1253. The main branch of the Order (O.S.C.) follows the observance of Pope Urban. Other branches established since that time, who operate under their own unique Constitutions, are the Colettine Poor Clares (P.C.C.) (founded 1410), the Capuchin Poor Clares (O.S.C. Cap) (founded 1538) and the Poor Clares of Perpetual Adoration (P.C.P.A.) (founded 1854). The Poor Clares were founded by Clare of Assisi in 1212. Little is known of Clare's early life, although popular tradition hints that she came from a fairly well-to-do family in Assisi. At the age of 17, inspired by the preaching of Francis in the cathedral, Clare ran away from home to join her community of friars at the Portiuncula, some distance outside the town. Although, according to tradition, her family wanted to take her back by force, Clare's dedication to holiness and poverty inspired the friars to accept her resolution. She was given the habit of a nun and transferred to Benedictine monasteries, first at Bastia and then at Sant' Angelo di Panzo, for her monastic formation. By 1216, Francis was able to offer Clare and her companions a monastery adjoining the chapel of San Damiano where she became abbess.
