Answer:
July 28 1914
Step-by-step explanation:
World War I, also known as the Great War, started on July 28, 1914.
The causes of World War I are complex and multifaceted, with a combination of long-term and immediate factors contributing to the outbreak of the war. Some key causes include:
Nationalism: Intense nationalism and the desire for self-determination were prevalent in Europe during the late 19th and early 20th centuries. This led to rivalries and competition between nations, often fueled by territorial disputes and the pursuit of power.
Imperialism: European powers were engaged in an era of imperialism, seeking to expand their empires and assert control over colonies and territories. The competition for colonies and resources created tensions among the major powers.
Alliances and Ententes: Europe was divided into two main alliance systems. The Triple Entente, comprising France, Russia, and the United Kingdom, opposed the Triple Alliance, consisting of Germany, Austria-Hungary, and Italy. These alliances created a delicate balance of power, but also contributed to an escalation of tensions.
Militarism: A significant arms race occurred among European powers, with each nation investing heavily in military buildup and modernization. This heightened militarism fostered a sense of readiness for conflict and increased the risk of war.
Assassination of Archduke Franz Ferdinand: The assassination of Archduke Franz Ferdinand of Austria-Hungary and his wife by a Serbian nationalist on June 28, 1914, in Sarajevo, Bosnia, acted as the immediate trigger for the war. This event set off a chain reaction of diplomatic crises and mobilizations, leading to the outbreak of hostilities.
It is important to note that these causes are simplified explanations, and the origins of World War I are subject to ongoing historical debate. The interplay of these factors, along with other complex dynamics, contributed to the outbreak of the conflict.
