Page "Second Council of the Lateran" Paragraph 0

The Second Council of the Lateran is believed to have been the Tenth Ecumenical Council by Roman Catholics.

It was held by Pope Innocent II in April 1139, and was attended by close to a thousand clerics.

Its immediate task was to neutralise the after-effects of the schism, which had arisen after the death of Pope Honorius II in February 1130 and the setting up of Petris Leonis as the antipope Anacletus II.
