Final answer:
The Triple Entente was created in 1907 between Great Britain, France, and Russia in response to the rise of German power and stood against the Central Powers in World War I, with Italy and the United States later joining the Entente.
Step-by-step explanation:
The Triple Entente was a military alliance formed in 1907, comprising of Great Britain, France, and Russia. This alliance emerged from mutual defense agreements and a common concern about the rise of German power in continental Europe. Notably, the Triple Entente stood against the Central Powers of Germany, Austria-Hungary, and initially Italy, which later switched sides in 1915. The spark that ignited the cooperation among these great powers was their shared distrust and the desire to curb German ambition through strategic alliances.
When World War I commenced, the Triple Entente and its eventual allies, including the United States, faced off against the Central Powers in a conflict characterized by extensive military mobilization, nationalism, and a complex web of international alliances. Italy joined the Entente powers in 1915, while the United States entered the war in support of the allies in 1917.
