Theobald von Bethmann Hollweg
He became Reich Chancellor in July 1909, succeeding Bernhard von Bülow. Before the war he tried in vain to improve relations with the United Kingdom. During the war he unsuccessfully opposed the launching of the U-boat warfare without any restrictions in March 1917. Because of peace efforts of the Reichstag he resigned in July 1917, and was succeeded by Georg Michaelis.
