The Struggle for Power: The Investiture Controversy
The Investiture Controversy was a major power struggle between medieval popes and kings over who had the right to appoint (invest) bishops, which came to a head in 1075 when Pope Gregory VII banned kings from appointing church officials and excommunicated Holy Roman Emperor Henry IV, as covered in Pengi Social Studies Grade 7, Chapter 7: Medieval Europe. Henry was forced to stand barefoot in the snow at Canossa to beg forgiveness, establishing that the Papacy held supreme authority over spiritual matters.
Key Concepts
As the Church grew wealthy (owning 1/3 of Europe's land) and powerful, it clashed with secular rulers. The biggest conflict was the Investiture Controversy : who had the right to appoint (invest) bishops—the King or the Pope? Bishops were often wealthy landowners, so kings wanted to control them.
In 1075, Pope Gregory VII banned kings from appointing church officials. When Holy Roman Emperor Henry IV defied him, Gregory excommunicated the Emperor. Faced with rebellion from his own nobles, Henry was forced to stand barefoot in the snow at Canossa to beg forgiveness. This victory established that the Papacy held supreme authority over spiritual matters.
