its territories in Italy, struggled with the Sassanid Empire to the east for a period of more than 400 years. Large-scale incursions of Germanic tribes, such as the Goths and Hunnic raids in the west began during the fourth century and lasted for more than a hundred years. Seven Years' War The French and Indian War was a local conflict in North America, that occurred in the context of the trans-continental Seven Years' War. In 1755 armed forces of Great Britain under the command of General Edward Braddock invaded the territories of New France (eastern part of modern Canada, Mississippi and Ohio River Valleys and much of the upper Midwest of the modern United States) and attacked Fort Duquesne. Although numerically superior to the local French militia and their Indian allies, the British army became ensnared in a two-front conflict and was routed. Prussia had to fight against France, Austria, and Russia during the Third Silesian War, and also against Sweden during the Pomeranian War. Napoleonic Wars During the Napoleonic Wars, the Grande Armée of France regularly maintained multiple fronts. In the seven year long Peninsular War (1807–1814) imperial French contingents and Spanish and Anglo-Portuguese armies wrestled for control of the Iberian Peninsula in numerous battles. Nonetheless, in 1812 as French military presence in Iberia had begun to decline, emperor Napoleon Bonaparte personally lead an army of more than 600.000 troops to the east into Russia, seeking to decisively defeat the Russian Empire and force Tsar Alexander I to comply with the Continental System. Great Britain was also present on multiple fronts of the Napoleonic Wars in Europe and the Canadian, the Chesapeake Bay and Louisiana theaters of the War of 1812 in North America. World War I Germany During World War I, Germany fought a two-front war against France, Great Britain, Italy, Belgium and later also American forces on the Western Front and Russia and later Romania on the Eastern Front. Russian participation in the war ended with the 1917 Bolshevik October Coup and the peace treaty with Germany and Austria-Hungary was signed in March 1918. Its central location in Europe and (currently) borders with nine neighboring nations fundamentally define Germany's politics and strategy. Bismarck successfully integrated Germany in his elaborate system of alliance of the European powers from 1871 until he was dismissed in 1890 by the new Emperor Wilhelm II. Wilhelm embarked on an imperialist great power
