Conrad III vs Henry V

Conrad III engaged in a civil war with the Welf party, led by Henry the Proud and later Henry the Lion, from 1138 to 1142. The conflict ended with a compromise that allowed the Welfs to retain some territories.

Conrad III was elected King of Germany in 1138, becoming the first ruler of the Hohenstaufen dynasty. His election was opposed by the Welf party, leading to a prolonged conflict with Henry the Proud.

Conrad III led the German contingent of the Second Crusade to the Holy Land in 1147-1148. His army was defeated by the Seljuk Turks at the Battle of Dorylaeum in 1147, and the crusade ended in failure.

Conrad III participated in the Siege of Damascus in July 1148 during the Second Crusade. The siege failed after only four days due to internal disputes among crusader leaders, leading to the crusade's collapse.

Henry V was elected King of Germany in 1106 after rebelling against his father Henry IV, who died the same year. His accession marked the continuation of the Salian dynasty amid the Investiture Controversy.

Henry V led a military campaign to Italy in 1110-1111 to assert imperial claims over the Papal States and secure his coronation. He captured Rome and forced Pope Paschal II to concede investiture rights, but the agreement was later repudiated.

Pope Paschal II crowned Henry V Holy Roman Emperor in Rome on April 13, 1111, after Henry forced the Pope to grant him the right of investiture. The coronation followed a tense standoff where Henry imprisoned the Pope and cardinals.

Henry V and Pope Callixtus II signed the Concordat of Worms on September 23, 1122, ending the Investiture Controversy. The agreement gave the Church the right to elect bishops but allowed the emperor to invest them with secular authority.
