Answer :
Germany played a central role in European instability from 1914-1945 due to its unification, military alliances, territorial ambitions, and key involvement in both World Wars.
Germany was at the forefront of European instability from 1914-1945 due to its rapidly growing industrial, military, and political power which disrupted the previously established balance of power. The unification of Germany under Otto von Bismarck, followed by the annexation of Alsace-Lorraine from France, stoked national rivalries and led to the formation of strategic military alliances. These pivotal events, alongside the complex web of alliances, set the stage for the conflicts that ensued during the World Wars.
During World War I, Germany's position as part of the Central Powers saw it in direct conflict with the Allied nations, leading to devastating losses and the fall of the German Empire. Post-war, the Treaty of Versailles and the creation of the German Republic further sowed the seeds of discontent that would later contribute to the rise of the Nazi regime and the outbreak of World War II.
Germany's role in European instability was further compounded by the ambitions of the Nazi leadership, its economic influence in South-East Europe, the quest for territorial expansion, and the resulting global conflict, which drew in nations worldwide, causing a massive loss of life and altering the geopolitical landscape greatly.
