Investiture Controversy

The Investiture Controversy was the most significant conflict between secular and religious powers in medieval Europe. It began as a dispute in the 11th century between the Holy Roman Emperor and the Gregorian Papacy concerning who would control appointments of church officials (investiture). The controversy, undercutting the Imperial power established by the Salian Emperors would eventually lead to nearly fifty years of civil war in Germany, the triumph of the great dukes and abbots, and the disintegration of the German empire, a condition from which it would not recover until the reunification of Germany in the 19th century.

On the Continent, after fifty years of fighting, a similar compromise (but with quite different long-term results) was reached in 1122, signed on September 23 and known as the Concordat of Worms. It was agreed that investiture would be eliminated, while room would be provided for secular leaders to have unofficial but significant input in the appointment process.
