Question 3

In World War I, after Austria - Hungary declared war on Serbia, Russia supported Serbia. Then Germany declared war on Russia. France, being an ally of Russia, was next. The United Kingdom also declared war on Germany and Austria - Hungary due to treaty obligations and the violation of Belgian neutrality. So the main nations that declared war against Germany and the Austro - Hungarian Empire were France, the United Kingdom, Russia, and later the United States (among others, but these were the key initial ones in the Allied Powers).

The Schlieffen Plan was Germany's pre - World War I military strategy. The plan was to quickly defeat France by attacking through Belgium (since France's eastern border was heavily fortified) and then turn all forces to fight Russia in the east, as Russia was expected to take longer to mobilize. In 1914, when the war started, Germany implemented the plan. However, the attack through Belgium was met with more resistance than expected, and the Russian mobilization was faster than anticipated. The Battle of the Marne in September 1914 stopped the German advance towards Paris, so the Schlieffen Plan failed as Germany got bogged down in a two - front war (Western Front with France and Eastern Front with Russia) instead of a quick victory over France first.

The Russian Revolution (February and October Revolutions in 1917) had a major impact on World War I. The February Revolution led to the abdication of the Tsar, and the new Provisional Government initially continued the war. But the October Revolution (Bolshevik takeover) led to Russia's withdrawal from the war. The Treaty of Brest - Litovsk (1918) ended Russia's participation, which allowed Germany to transfer troops from the Eastern Front to the Western Front. However, this also meant the Allies lost a major power, and the revolution inspired anti - war and socialist movements in other countries, affecting morale and the political landscape of the war.

Answer:

France, the United Kingdom, Russia, and later the United States (and other Allied nations) declared war against Germany and the Austro - Hungarian Empire.
