Final answer:
After World War I, Germany experienced territorial and political changes, including the loss of territories and the transition to a democratic republic. The Austro-Hungary empire was dissolved, leading to the emergence of new countries.
Step-by-step explanation:
Germany:
After World War I, Germany experienced significant territorial changes, political changes, and other developments. Territorially, Germany lost substantial territories as dictated by the Treaty of Versailles. The most notable loss was the regions of Alsace-Lorraine, which were returned to France. Additionally, Germany lost territory to Belgium, Denmark, and Poland.
Politically, the German monarchy was abolished, and the country became a democratic republic known as the Weimar Republic. This transition led to social and political unrest, contributing to the rise of extremist movements like the Nazi Party.
Other significant developments included severe economic struggles, high inflation, and the implementation of war reparations as part of the Treaty of Versailles.
Austria-Hungary:
World War I had a profound impact on the Austria-Hungary empire. The assassination of Archduke Franz Ferdinand, the heir to the Austro-Hungarian throne, sparked the war. After his assassination, Austria-Hungary declared war on Serbia, leading to a chain reaction that engulfed Europe in conflict.
The war ultimately led to the dissolution of the Austria-Hungary empire. The empire was carved up, and new countries emerged, including Austria, Hungary, Czechoslovakia, and Yugoslavia. This change marked the end of Austria-Hungary as a multinational empire.
Russia:
World War I had significant effects on Russia, including political changes like the Russian Revolution and the shift to a communist government. The war put immense strain on Russia's resources, leading to economic hardships and food shortages for its population.
The Russian Revolution of 1917 resulted in the overthrow of the monarchy and the establishment of a communist government under Vladimir Lenin. This revolution marked a major turning point in Russian history, leading to the formation of the Soviet Union.
