Page "First Council of the Lateran" Paragraph 2

The First Lateran Council was called by Pope Callistus II whose reign began February 1, 1119.

It demarcated the end of the Investiture controversy which had begun before the time of Pope Gregory VII.

The issues had been contentious and had continued with unabated bitterness for almost a century.

Guido, as he was called before his elevation to the papacy, was the son of William I, Count of Burgundy.

He was closely connected with nearly all the royal houses of Europe on both sides of his family.

He had been named the papal legate to France by Pope Paschal II.

During Guido's tenure in this office, Paschal II yielded to the military threats of Henry V, Holy Roman Emperor, and was induced to issue the Privilegium in the year 1111.

By this document the Church gave up much of what had been claimed and subsequently attained by Pope Gregory VII and his Gregorian Reforms.
