How did the participation of the united states in world war 1 contributed to its becoming a world power? ?

The United States declared war on Germany on April 6, 1917, during World War I. The U.S. was an independent power and did not officially join the Allies. It closely cooperated with the Allies militarily but acted alone in diplomacy. The U.S. made its major contributions in terms of supplies, raw material and money, starting in 1917. American soldiers under General John Pershing, Commander-in-Chief (C-in-C) of the American Expeditionary Force (AEF), arrived in large numbers on the Western Front in the summer of 1918. Before entering the war, the U.S. had remained neutral, though it had been an important supplier to Great Britainand the other Allied powers. During the war the U.S. mobilized over 4 million military personnel and suffered 110,000 deaths, including 43,000 due to the influenza pandemic.[1] The war saw a dramatic expansion of the United States government in an effort to harness the war effort and a significant increase in the size of the U.S. Armed Forces. After a relatively slow start in mobilizing the economy and labor force, by spring 1918, the nation was poised to play a role in the conflict. Under the leadership of President Woodrow Wilson, the war represented the climax of the Progressive Era as it sought to bring reform and democracy to the world, although there was substantial public opposition to U.S. entry into the war.

They were constantly being overlooked as a people and were being controlled by people who weren't really native to their homeland.
