1917 Code of Canon Law

The 1917 Code of Canon Law (abbreviated 1917 CIC, from its Latin title Codex Iuris Canonici), also referred to as the Pio-Benedictine Code,[1] was the first official comprehensive codification of Latin canon law. It was promulgated on 27 May 1917 and took legal effect on 19 May 1918.[2] It was in force until the 1983 Code of Canon Law took legal effect and abrogated it[1] on 27 November 1983.[3] It has been described as "the greatest revolution in canon law since the time of Gratian"[4] (1150s AD).
