Following the death of Winrich von Kniprode, Konrad was elected Grandmaster of the Teutonic Order on October 5, 1382.

He reformed the administrative structure of Teutonic Prussia, promoted German settlement, and attempted to found a university in the city of Kulm, though the latter never came to fruition.

He also, like his predecessor, combated usery, reducing the maximuim interest rate from 10% to 8.33%, with violators having their capital confiscated.

This meant that Lithuania and Poland, who was the primary rival of the Teutonic Order, had entered into a personal union.

In his later reign, the order was beset by numerous internal issues; in 1383, a plague outbreak occurred, and in later years, crop failures, and declining fishing and trade output wreaked havoc upon the state.
