Clare of Assisi

Chiara Offreduccio (16 July 1194 – 11 August 1253), known as Clare of Assisi (sometimes spelled Clara, Clair or Claire; Italian: Chiara d'Assisi), is an Italian saint who was one of the first followers of Francis of Assisi.

Inspired by the teachings of St. Francis, St. Clare founded the Order of Poor Ladies, a monastic religious order for women in the Franciscan tradition. The Order of Poor Ladies was different from any other order or convent because it followed a rule of strict poverty. Clare wrote their Rule of Life, the first set of monastic guidelines known to have been written by a woman. Following her death, the order she founded was renamed in her honor as the Order of Saint Clare, commonly referred to today as the Poor Clares. Her feast day is on the 11th of August every year.
