Which group of nations was originally formed during World War I that included Great Britain, France, and Russia?

The group of nations that was originally formed during World War I and included Great Britain, France, and Russia is known as The Allies. This coalition opposed the Central Powers, which comprised Germany, Austria-Hungary, and the Ottoman Empire. The Allies came together to combat the aggressive expansion of the Central Powers, and their collaboration was crucial in various military campaigns throughout the war.

The term "Allies" reflects a military alliance formed for a common goal, specifically defeating the adversary in conflict. This collaboration laid the groundwork for later international alliances and organizations, influencing global diplomatic relations in the aftermath of the war.

The other groups mentioned do not apply to this context; for instance, the Axis refers to the alliance of Germany, Italy, and Japan during World War II, while the Central Powers were the adversaries of the Allies in World War I. The United Nations, on the other hand, was established after World War II in an effort to promote international cooperation and prevent future conflicts.
