The First World War represented a transformative period in global politics, marking the ascent of the United States as a dominant world power. This era was characterised by significant shifts in international relations, heavily influenced by the USA's involvement in the war.
Factors Leading to the USA’s Entry into WWI
Economic Interests and Neutrality
- The United States initially adopted a position of neutrality, guided by President Woodrow Wilson’s philosophy of non-intervention.
- Economic Ties with the Allies: The USA's economic relationship with the Allied Powers grew stronger as the war progressed. The nation's trade with Britain and France increased significantly, and the USA extended substantial loans to these countries, solidifying an economic bond that gradually aligned the USA with the Allies.
Unrestricted Submarine Warfare
- German U-boat Campaign: Germany's strategy of unrestricted submarine warfare, particularly the sinking of the RMS Lusitania in 1915, which resulted in American casualties, played a significant role in changing public opinion in the USA against Germany.

The Zimmerman Telegram
- The Zimmerman Telegram was a pivotal moment in the USA's decision to enter the war. Intercepted and decoded by British intelligence, the telegram revealed Germany's proposal for a military alliance with Mexico against the USA, promising the return of territories lost during the Mexican-American War. This was perceived as a direct threat to US national security.
Political and Ideological Factors
