The Poor Clares, officially the Order of Saint Clare (Latin: 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 an enclosed order of nuns in the Roman Catholic Church. The Poor Clares were the second Franciscan branch of the order to be established. The first order of the Franciscans, which was known as the Order of Friars Minor, was founded by Saint Francis of Assisi in 1209. Three years after founding the Order of Friars Minor, Francis of Assisi and Clare of Assisi founded the Order of Saint Clare, or Order of Poor Ladies, on Palm Sunday in the year 1212. They were organized after the manner of the Order of Friars Minor and before the Third Order of Saint Francis was founded. 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 (OSC) follows the observance of Pope Urban. Other branches established since that time, who operate under their own unique Constitutions, are the Colettine Poor Clares (PCC) (founded 1410), the Capuchin Poor Clares (OSCCap) (founded 1538) and the Poor Clares of Perpetual Adoration (PCPA) (founded 1854).
