The Fourth Lateran Council, presided over by Pope Innocent III in 1215, introduced significant reforms to marriage practices within the church. Most notably, the council made the publication of banns of marriage—the public legal notice of an impending marriage—compulsory.1
This requirement was intended to allow any person aware of a legal impediment to the union to come forward and make their objections known before the marriage could be solemnized. By formalizing this process, the church sought to ensure greater transparency and adherence to canonical regulations regarding matrimony.1
