Vienna Conference (March 1917)
The Vienna Conference of 16 March 1917 was the first German-Austro-Hungarian meeting since the outbreak of the February Revolution in Russia. For Reich Chancellor Theobald von Bethmann Hollweg, the ministerial meeting was a further opportunity to reaffirm the Reich's war aims in the face of the dual monarchy's new Foreign Minister, Ottokar Czernin.
