The alliance system was a key feature of international relations in the late 19th and early 20th centuries. It refers to the complex web of political and military alliances that European powers formed to protect themselves and advance their interests.
The two main alliances that emerged were the Triple Alliance and the Triple Entente:
Triple Alliance: Formed in 1882, this alliance consisted of Germany, Austria-Hungary, and Italy. It was primarily a defensive alliance aimed at countering the power of France and Russia.
Triple Entente: Established in 1907, this alliance included France, Russia, and the United Kingdom. It was formed in response to the growing strength of the Triple Alliance and the perceived threat it posed.
