After the death of ruler of Prussia Fredrick Willian IV in 1861, sixty four years (64) old William I became the ruler. His brain was not so brilliant and thoughtful but he had a strange quality of testing able people. He believed in liberalism but he believed that unification of Germany can be done by Prussia through powerful rule and military. To strengthen the military of Prussia Banrun was made war friend and Wammollake was made Chief Commander. When constitutional hindrance occurred on the issue of military reforms, then to remove this hindrance William I appointed the Bismarck as his chancellor. Bismarck was a cunning politician a well known person of international matters skilled and diplomat wealthy personality. According to him the problems of that period couldn’t be solved by the speech and majority resolutions but could be solved by the policy of iron and blood hence due to this cause to make Prussia powerful when military budget was not accepted by the lower house of the Parliament then Bismarck got it passed by the upper house and introduced his firm determination.
