who were the allies in ww1

The Allies in World War I were the coalition of countries that fought against the Central Powers (Germany, Austria‑Hungary, the Ottoman Empire, and Bulgaria) between 1914 and 1918.

Core Allied Powers

The main “great power” Allies were:

• France – Fought Germany from the Western Front.
• British Empire (including the United Kingdom and dominions like Canada, Australia, New Zealand, and India).
• Russian Empire – Fought Germany and Austria‑Hungary in the East until it withdrew after the 1917 revolution.
• Italy – Joined the Allies in 1915 after switching sides from the pre‑war Triple Alliance.
• United States – Entered the war in 1917 as an “Associated Power,” not a formal treaty‑bound ally, but still fought alongside the Entente.

Other Key Allied States

Several smaller or regional powers also joined the Allies, including:

• Belgium – Invaded by Germany in 1914; its resistance helped draw Britain into the war.
• Serbia – One of the first combatants after the 1914 assassination of Archduke Franz Ferdinand.
• Japan – Entered in 1914, mainly fighting Germany in Asia and the Pacific.
• Romania , Portugal , Greece , Brazil , and others joined later in the conflict.

How They Were Organized

The Allies were often called the Entente Powers , originally built around the Triple Entente (France, Russia, and Britain).

• A 1914 treaty bound Britain, France, and Russia not to make a separate peace with the Central Powers, solidifying the “Allies” label.

• By the 1919 Treaty of Versailles, the final list of “Allied and Associated Powers” included about 27 countries , from Belgium and France to smaller states such as Liberia, Panama, and Siam (Thailand).
