url2.htmCountries were not independent at the time of World War 1.The United States wanted to stay neutral so they didn't join the Allied powers just yet. The main allies were France the Russian Empire, the British Empire,Italy and the United States. The United States declared War on Germany by attacking international shipping and because of the Telegram, which was about Germany sending a telegram to Mexico stating that if the U.S. was to announce war on them, that Mexico was to declare war on them so as to distract the U.S. and hopefully stop the United States from joining World War 1.The U.S entered the war as the associated power. The British Empire made significant contributions to the allied war effort even though they were/t as independent.
