What are the two alliances of Europe's great powers?

The two main alliances of Europe's great powers in the early 20th century were the Triple Alliance and the Triple Entente. The Triple Alliance consisted of Germany, Austria-Hungary, and Italy, while the Triple Entente comprised France, Russia, and the United Kingdom. These alliances created a complex web of commitments and rivalries that contributed to the outbreak of World War I. The tensions between these alliances significantly influenced European politics and military strategies during that era.
