Answer
Wilhelm II, the last German Emperor and King of Prussia, was Caprivi's primary superior during his tenure as Chancellor of Germany. Caprivi served under Wilhelm II from 1890 to 1894, implementing various domestic and foreign policies that sought to maintain Germany's stability and power. Although Caprivi's rule was relatively short-lived and marked by certain challenges, he played a significant role in shaping Germany's political landscape during the late 19th century.
