Paul von Hindenburg's command became known as the Dritte OHL (Third OHL) but Hindenburg was "neither the intellectual centre of the strategic planning [...] nor of the new war economy",[1]:513 as proposed in the Hindenburg Programme of 31 August 1916. He was mostly a figurehead and a representative of the military command to the public. Control was mainly exercised by his deputy, General of Infantry Erich Ludendorff, who held the title Erster Generalquartiermeister (First Quartermaster General).[lower-alpha 1][1]:513-514 The duumvirate increasingly dominated decision making on the German war effort, to an extent that they are sometimes described as de facto military dictators, supplanting the Emperor and Chancellor Theobald von Bethmann-Hollweg, whom they managed to have replaced with Georg Michaelis in the summer of 1917.[lower-alpha 2][7]:19–20
