The Fourth Council of the Lateran was summoned by Pope Innocent III with his Bull of April 19, 1213. The assembly took place in November, 1215. It was the 12th ecumenical council and is sometimes called "the General Council of Lateran" due to the attendance by seventy-one patriarchs and metropolitans, four hundred and twelve bishops, and nine hundred abbots and priors.
