Quick Summary

The term "Dacheriana" refers to a canonical collection compiled around 850 CE. This collection was a systematic integration of the Dionysiana and the Hispana, two earlier canonical compilations. The Dacheriana was influential in the development of canon law until the Gregorian Reform in the 11th century.1

Canon law itself is the body of laws and regulations made by ecclesiastical authorities for the government of the Christian church and its members. Its development in the West involved various collections and councils, aiming to unify church discipline and regulation. Gratian's Decretum, compiled around 1140, became a foundational text for the study of canon law, attempting to resolve contradictions within existing rules by referencing Roman law and the writings of Church Fathers.21
