19. Theobald von Bethmann-Hollweg (1856-1921)
Alongside Kaiser Wilhelm II, Bethmann-Hollweg served as Chancellor of Germany from 1909-17; essentially the period in which World War I ensued.
Despite the clamor of the war, Bethmann-Hollweg sought to maintain social and political coherency as the German liberal elites began to clash intensely with the German military machine and monarchist state. In his role, he gradually adopted a liberal political perspective which caused more tension with the diametrical opposition.
Despite his reluctance to go to war in 1914, he handed a declarative blank cheque to Austria-Hungary, which to all appearances, assumed that he was in favor of war. After he realized the global scale on which the War would take place, he tried to make a sole effort to reverse the military situation, which abruptly failed due to his lack of political authority.
