Pre-Tridentine Mass refers to the evolving and regional forms of the Catholic Mass in the West from antiquity to 1570. The basic structure solidified early and has been preserved, as well as important prayers such as the Roman Canon.
Following the Council of Trent's desire for standardization, Pope Pius V, with his bull Quo primum, made the Roman Missal obligatory throughout the Latin Church, except for those places and congregations whose distinct rites could demonstrate an antiquity of two hundred years or more.
