The conflict between Emperor Frederick I Barbarossa of Germany and Pope Clement III is settled when the Peace of Strasbourg is signed.
The emperor agrees to remove his forces from the papal states, but without giving up all imperial rights to the territory — so in a sense he is removed but retains at least theoretical authority.
In return, Pope Clement III promises to crown Frederick's son, Henry VI, as emperor. Frederick Barbarossa keeps his side of this agreement, but Pope Clement III doesn't; instead he will actively promote Tancred of Lecce to take the Sicilian throne. That plan won't work, however, and Henry VI will take the crown himself in 1194.
