By 1914, Europe had become divided into two armed camps largely due to a complex system of alliances and rising nationalism. The Triple Alliance, consisting of Germany, Austria-Hungary, and Italy, was pitted against the Triple Entente, formed by France, Russia, and Britain. Tensions escalated with militarism and colonial rivalries, particularly in the Balkans, leading to an arms race and a climate of distrust. The assassination of Archduke Franz Ferdinand in June 1914 acted as a catalyst, triggering a series of events that ultimately plunged Europe into World War I.
The first camp consisted of Great Britain, France, and Russia, which became the Allied Powers. The second camp included Germany and Austria-Hungary, which became the Central Powers.
