Which figure is known for establishing a female order called the Poor Clares?

The figure known for establishing a female order called the Poor Clares is Francis of Assisi. In the early 13th century, he inspired a group of women to live a life of poverty and devotion, leading to the formation of the Order of St. Clare, commonly referred to as the Poor Clares. This order followed the rule of St. Francis, focusing on living a life of simplicity, community, and service to the church and the poor.

Francis was particularly influential in promoting the ideals of humility and service, which resonated deeply with those seeking to live a spiritual life apart from worldly attachments. He emphasized the importance of living out one's faith through practical actions and a deep connection to God.

The other figures mentioned—Jerome, Gregory the Great, and Anselm—were significant in their own rights, contributing to theology and biblical translation, but they were not associated with the establishment of the Poor Clares or a similar female religious order. Thus, Francis of Assisi stands out as the founding figure of this important movement within the Church.
