By the early 1800s the Germany we know today was constructed of 39 independent states the largest of which was Prussia. These states shared similar culture and industry which in turn brought them closer together. 1Though this caused a problem in Europe since they thought unified Germany would be too powerful. At the time there was one main leader for German unification, Otto von Bismarck. He followed a philosophy known as realpolitik, a system of politics principles based on practical rather than more moral or ideological considerations. Bismarck United the various kingdoms of German into one unified state. He started three wars to accomplish his goal but after unification he successfully maintained peace in europe. This unified Germany one of the most militarily dominant nation in Europe.Bismarck had near absolute control over his country, and when he resigned his power is passed on to his successors. 1The following German leaders would ignore The philosophy of realpolitik and favor of militaristic illusions. Otto von Bismarck utilized his  leadership as well as philosophy of realpolitik to unify Germany and maintain peace in Europe. Subsequent German leaders would disregard Bismarck’s ideals, as his obsession with individual power failed to create a long lasting germany. Thus leaving to a tainted legacy.Otto von Bismarck born in the year 1815. At this time the 39 States ruled over the German people and were loosely united under the German Confederation led by Austria. 1848 revolution exploded across Europe. German Rebels hoped to unite the country under liberal principles such as universal suffrage. German rulers would not accept liberalism and the rebels failed. However the spirit of German nationalism that the rebels created lived on. “there’s obviously no Germany but there is a feeling that there is a nationality that is German”- professor Matthew handelman, Michigan State. Born to prussian nobles, Otto von Bismarck was taught to despise such liberal thoughts. He studied law at the University of gottingen where several of his early contemporaries took notice of his motives to rule and a power over other people. Moving into 1847 Bismarck began his career in the prussian government. Later in 1851 he was sent as Prussians Envoy to the Leader of the German Confederation. Here he became an advocate of a new philosophy realpolitik, a form of realism adopted and later perfected by bismarak. It approach politics with a pragmatic foundation. 2Realpolitik and its roots of realism was derived from political philosophers such as Thomas Hobbes and Nikolai Makaveli. Both of which stressed the importance of power at a national interest. In realpolitik the means of achieving power or control sometimes the immortal.”the main thing is to make history not to write it.” Said Otto von Bismarck. In 1862, king Wilhelm, made bismarck the first prime minister of prussia. 2As a leader bismarck was initially against nationalism but under his philosophy of realpolitik he realized that National could be used to further prussia’s power. He wished to lead Prussia using the Nationalist, while disregarding the demands for democracy. While willham was King by law Bismarck had complete power over him would be deciding the future of Prussia. Hoping to expand Prussias power Bismarck orchestrated three wars the second schleswig war vs denmark, The austro-Prussian war vs austria and the Franco-Prussian War vs France. This not only Prussia but resulted in the unification of germany. Johann Gottlieb Fichte “The first, original, and truly natural boundaries of states are beyond doubt their internal boundaries. Those who speak the same language are joined to each other by a multitude of invisible bonds by nature herself, long before any human art begins; they understand each other and have the power of continuing to make themselves understood more and more clearly; they belong together and are by nature one and an inseparable whole.” Addresses to the German Nation (1806).The surge of German unification prior to 1871 was caused by the experience of Germans in the Napoleonic period. In this period ideas shifted political, social, and cultural relationships within the German states. Thus, sparking the flame into a nationalistic idea and giving birth to identify “Germany” as a single state. In addition, Otto von Bismarck intentionally, provoked war which helped him gain the support he needed from his people to create a united Germany.
