How did the Investiture Controversy influence religious literature in medieval Germany?

The Investiture Controversy, a power struggle between the papacy and the Holy Roman Empire, significantly shaped the development of early Middle High German religious literature. During the late 11th and 12th centuries, this conflict spurred the production of numerous religious texts that served as a form of propaganda for reactionary, ascetic movements advocating for church reform.12

These works often rejected the worldliness of secular rule and criticized the subordination of the church to the state, which had been a hallmark of the Carolingian, Ottonian, and Salian dynasties. To reach the laity and influence public opinion, these authors wrote in the vernacular rather than Latin. The literature frequently focused on the theme of memento mori, warning readers of the sinfulness of earthly life and urging them to view the world as an illusion or a trap set by the Devil.23

Ultimately, this period is noted for the fact that the first abundant texts in the German language emerged not from mainstream secular culture, but from a conservative religious reaction against the political and social order of the time.2
