4th+Lateran+Council

Ecumenical council invoked in 1213.

The council was gathered in order to respond to the conclusion of the 3rd and 4th crusades. One by product of the council was a list of 71 canons which served to standardize formalize church law during a period when the western church was over-extended militarily and at odds with the byzantine orthodox.
