- Congregation of the Holy Saviour
- 492 when the clergy of the Roman Basilica of Saint John Lateran adopted the Augustinian Rule under Gelasius
The canons served at the Basilica of Saint John Lateran until c.1472 when they were replaced by secular canons, though they retained their title and certain privileges. In addition to canonical duties, they serve pilgrims, tend the sick, teach, and preach. The Order spread to Italy, Poland, France, Belgium, Spain, and America. An affiliated congregation was founded in Austria in 1140. The Canons Regular of Reno were united to the Lateran Congregation in 1823.
