William inherited a conflict between Frederick William and the liberal Landtag. He was considered to be politically neutral as he intervened less in politics than his brother. In 1862 the Landtag refused an increase in the military budget needed to pay for the already implemented reform of the army. This involved raising the peacetime army from 150,000 to 200,000 men and boost the annual number of new recruits from 40,000 to 63,000. However, the truly controversial part was the plan to keep the length of military service (raised in 1856 from two years) at three years. When his request, backed by his Minister of War Albrecht von Roon was refused, William first considered abdicating, but his son, the Crown Prince, advised strongly against it. Then, on the advice of Roon, William appointed Otto von Bismarck to the office of Minister President in order to force through the proposals. According to the Prussian constitution, the Minister President was responsible solely to the king, not to the "Landtag". Bismarck, a conservative Prussian Junker and loyal friend of the king, liked to see his working relationship with William as that of a vassal to his feudal superior. Nonetheless, it was Bismarck who effectively directed the politics, domestic as well as foreign; on several occasions he gained William's assent by threatening to resign.
