What was the trigger for World War I? What were the countries that participated in the war at that t

A: The trigger for the First World War was the Sarajevo Incident: the Austro-Hungarian Crown Prince was shot dead by Serbian nationalists in Sarajevo in June 1914, and Austria-Hungary declared war on Serbia in July under the pretext of this.

More than 20 countries, including Britain, France, Japan, Italy, and the United States, participated in the Allied war; Germany, Austria-Hungary, Turkey, and Bulgaria fought on the side of the Allies.

The First World War was an imperialist war, and both sides were unjust. Although Serbia fought to defend its sovereign independence, this could not change the injustice of the war as a whole.

On June 28, 1914 (Serbian National Day), the Crown Prince of Austria-Hungary, Archduke Ferdinand and his wife, were shot dead by the Serbian youth Gavrio Princip while inspecting Sarajevo, which became the fuse of the First World War.

On July 28 of the same year, Austria-Hungary, with the support of Germany, declared war on Serbia under the pretext of the Sarajevo incident. Then Germany, Russia, France, Britain and other countries entered the war one after another, and World War I broke out. The warring parties were the German Empire and Austria-Hungary of the Central Powers, and the Ottoman Empire and Bulgaria that supported them.

On the other side were the Entente powers of Great Britain, France, and the Russian Empire, as well as Serbia, Belgium, Italy, and Japan, which supported them.

Italy, which was formerly part of the Central Powers, joined the Allied side of the war because of its stakes.

In order to expand its power in East Asia and invade China, Japan declared war on Germany in 1914 under the pretext of the "Anglo-Japanese Alliance" concluded in 1902, and quickly occupied Germany's sphere of influence in Shandong, China.

Causes of the First World War: On June 28, 1914, on the occasion of Serbia's National Day, the Archduke Ferdinand and his wife, the Crown Prince of Austria-Hungary, were shot dead by the Serbian youth Gavrio Princip while inspecting Sarajevo, which became the fuse of the First World War.

Events in Sarajevo.

First world war.

The trigger was the Sarajevo incident. The Sarajevo Affair took place on June 28, 1914 in Bosnia, the Balkans, and Archduke Ferdinand, the heir to the Austro-Hungarian throne.

On June 28, 1914 (Serbia's "Day of National Shame"), the Austro-Hungarian Crown Prince Franz Ferdinand and his wife Sofia were shooting dead by Serbian nationalist Gavrijo Princip while inspecting Sarajevo. The Entente and the Allied bloc took advantage of this sudden incident to add fuel to the fire, leading to a rapid deterioration of the international situation. Thus, the events in Sarajevo were later considered the trigger for the First World War.

After the Sarajevo incident, the German Emperor Wilhelm II wrote a "blank check" to Austria-Hungary, which made the Austro-Hungarian Emperor Franz Joseph I present an "ultimatum" to Serbia on July 23, 1914, and Serbia** accepted all the terms except Articles 5 and 6, and at the same time began the general mobilization for war. Austria-Hungary declared war on Serbia on July 28 because the Serbian side did not accept all the terms, and World War I officially began.
