On June 28, 1914, Gavrilo Princip, a Serbian from the Black Hand organization, assassinated the Hungarian crown heir in Sarajevo, sparking the onset of the First World War in Europe.
The war involved the Triple Alliance (Germany, Austro-Hungarian Empire, Italy) against the Triple Entente (France, Russia, United Kingdom), with alliances solidified in 1907.
The war's causes included nationalism, militarism, imperialism, and the system of alliances, leading to intense competition among powers.
The conflict escalated due to international instability, with militarism influencing decision-making and fostering exaggerated patriotism.
The war's global nature stemmed from alliances' economic and military competition, notably Germany's rivalry with England and Austria-Hungary's Balkan interests.
Four international crises, particularly in Morocco and the Balkans, heightened tensions and contributed to the outbreak of war.
The war commenced with Austria-Hungary declaring war on Serbia, leading to Russia and Germany's involvement, followed by France and other nations.
The Western Front saw fierce battles, with Germany initially advancing but facing setbacks, leading to trench warfare and the use of new weapons like chlorine gas.
The war concluded in 1918 after significant offensives and the entry of the United States, culminating in Germany's defeat, the Kaiser's abdication, and the signing of a harsh armistice, setting the stage for the Treaty of Versailles and the aftermath of the war.
