Theobald von Bethmann-Hollweg, German lawyer and politician, 5th Chancellor of Germany (b. 1856)

Theobald Theodor Friedrich Alfred von Bethmann Hollweg (29 November 1856 – 1 January 1921) was a German politician who was the chancellor of the German Empire from 1909 to 1917. According to biographer Konrad H. Jarausch, a primary concern for Bethmann in July 1914 was the steady growth of Russian power, and the growing closeness of the British and French military collaboration. Under these circumstances he decided to run what he considered a calculated risk to back Vienna in a local small-scale war against Serbia, while risking a major war with Russia. He calculated that France would not support Russia. It failed when Russia decided on general mobilization, and his own army demanded the opportunity to use the Schlieffen Plan for quick victory against a poorly prepared France. By rushing through Belgium, Germany expanded the war to include the United Kingdom. Bethmann thus failed to keep France and Britain out of the conflict, which became the First World War.
