This paper presents the life and political career of the first German chancellor, Otto von Bismarck. At the beginning of this paper, his childhood and youth are described which were spent in alienation and lost. In his first political activities, Bismarck experienced the very failures that would completely transform him in coming years. By crossing into diplomatic waters, he discovered his natural environment. With experiences in diplomacy, he moved into the service of chancellor to King William during an uncertain period of time in the kingdom. After the resolution of internal political disputes and conflicts, Bismarck turned to his supreme goal, namely the formation of the German state. Thanks to his abilities, the task was completed in a record period of only 8 and a half years. After the formation of the German Empire he turned to internal issues and peaceful foreign policy. In this period Bismarck encountered the biggest challenges and failures that he would deal with for the rest of his career. With the coming of the new emperor to power, Bismarck's old support disappeared and constant quarrels resulted in the resignation of the Iron Chancellor. He spent the rest of his life at his estate, writing memoirs about his past and reviews of the events of that time. Otto von Bismarck remained known as the greatest politician of the 19th century and the Father of the unified German state.
