World War I, or the Great War, began on July 28, 1914, engulfing Europe in a conflict between the Allies and the Central Powers. Initially, the U.S. aimed to maintain neutrality, with public opinion mixed and isolations tendencies prevalent. However, German U-Boat attacks and violations of neutral rights, including the sinking of the Lusitania, stirred American sentiments. By April 1917, driven by threats to American interests and the notorious Zimmermann Telegram, the U.S. declared war, ultimately joining the Allies in a decisive conflict that reshaped global dynamics.
