Hint: The First World War, also known as the Great War, was a military struggle that, along with Russia, the United States, the Middle East and other countries, embroiled most European nations in 1914–18.
The Central powers - mainly Germany, Austria-Hungary, and Turkey— were especially against the Allies—mainly France, Great Britain, Russia, Italy, Japan, and, from 1917, the United States.
The killing of the leading Austrian family, Archduke Francis Ferdinand, was the spark that set WW1 on fire. In 1914, after the killing of Archduke Franz Ferdinand of Austria, World War I, also known as the Grand War, began. He was killed in a battle that lasted in Europe until 1918.
The following series of incidents also happened since the assassination of Archduke Francis Ferdinand:
i) 28 July – Austria has proclaimed Serbia to be the battle.
ii) Germany declares war on Russia, an ally of Serbia, as the Austrian ally. August 1.
iii) August 3 – Germany waged war on France, Russia's ally, and occupied neutral Belgium immediately.
iv) August 4 – France's ally, Great Britain, has declared war on Germany.
v) The US (President Wilson) announces that the US is neutral.
A daring assault and swift troop movements on both fronts consisted of the initial month of the war. In the West, first Belgium and then France was invaded by Germany. To the east, Germany, as well as Austria-Hungary, invaded Russia. South of Serbia was invaded by Austria-Hungary. The Western front was enshrined in central France after the Battle of the Marne (5-9 Sept. 1914), and remained so for the remainder of the conflict. The eastern fronts are now increasingly locked up.
Two major advances emerged in 1917, including the stalemate on both fronts in Europe. The United States declared war on Germany in early April, with strikes on its Atlantic ships. The Bolshevik Revolution led Russia to withdraw from the war in November.
Although in 1918 the two parties started fresh offensives in an attempt to win the war, the attempts were unsuccessful. There was the continuous struggle against depleted, demoralised soldiers.
- An Allies' attack over the river Meuse and through the Argonne forest managed to drive the German depleted army close to the German frontier in August-September.
- In the meantime, a lethal influenza epidemic has taken heavy burdens from both sides of the military. Even after the two countries suffered repeated retreats from within their military institutions, the governments of both Germany and Austria-Hungary began to lose power.
- The Germans signed an armistice on 11 November 1918 in which they promised to give up their guns, abandon most of their navy and leave their occupied territories.
