Leo von Caprivi
He liked Bismarck, and once said "What jackass would dare to succeed Bismarck?". Kaiser Wilhelm II was arguing with Bismarck about changes to the government. In February 1890 the Kaiser told Caprivi to come back to Berlin. Caprivi was told that he would take over from Bismarck if Bismarck did not do what the Kaiser wanted. Caprivi became chancellor on 18 March 1890.
