In World War I, Germany achieved significant military successes early in the conflict, notably during the initial stages with the Schlieffen Plan, which aimed to quickly defeat France before turning to fight Russia. The German forces captured important territories, including Belgium and parts of northern France, and secured victories in battles such as Tannenberg and the Masurian Lakes against Russian forces in 1914. However, these successes were ultimately undermined by prolonged trench warfare and the entry of additional Allied powers, leading to Germany's eventual defeat.
