Background: After the fall of Napoleon in 1815, the Congress of Vienna attempted to restore the European balance of power. The Congress of Vienna exposed Europe to influential ideologies such as nationalism and conservatism; which at the time were two conflicting ideologies. The forces of nationalism and conservatism played the role in reforming the face of European politics until the outbreak of World War I. One instance can be seen with the unification of Germany in 1871; and it’s role after the Franco-Prussian War. Perhaps the most revolutionizing diplomatic event in the 19th century, Germany was now a major player in European politics. This unification as well as Italy’s produced alliances such as the Triple Entente and Three Emperor’s League to maintain the European balance of power. This convoluted system of checks and balances with alliances was bound to fail; this is evident by the events that led up to World War I.
