The history of the Angelus is a combination of what is certain and that which has been handed down in history. What is clear is that Franciscan houses and churches were already praying the Angelus by 1263. We have the liturgical texts prepared by the Franciscan Sinigardi di Arezzo that were in use in the 13th century. What is less certain, but carried in the tradition, is the origin of the prayer.
Tota Polchra Es Maria
On December 8, 1854, Pope Pius IX proclaimed the dogma of the Immaculate Conception. Centuries before that, St. Francis of Assisi initiated this devotion in the Order by decreeing at the second General Chapter of 1219 that a Mass in honor of Mary be said every Saturday in the friaries of the Order. St. Bonaventure introduced the feast into the Franciscan Order.
