What countries formed alliances in 1914 and why?

In 1914, two major alliances formed in Europe: the Triple Entente and the Triple Alliance. The Triple Entente consisted of France, Russia, and the United Kingdom, united primarily by mutual interests in countering German expansion and military power. The Triple Alliance included Germany, Austria-Hungary, and Italy, formed to provide mutual support against perceived threats from other nations, particularly France and Russia. These alliances were driven by national interests, military strategies, and colonial rivalries, ultimately contributing to the outbreak of World War I.
