Following a series of provocations by Germany, including the sinking of the Lusitania and the Zimmermann Telegram, President Wilson requested a declaration of war against Germany. The United States officially entered World War I, joining the Allied powers in their fight against the Central Powers. America's entry into the war marked a significant shift in public sentiment, with many citizens rallying behind the war effort in support of Wilson's call. However, there remained pockets of opposition to the war, particularly among certain ethnic groups, pacifists, and those wary of foreign entanglements.

United States Enters World War 1

The interception and decoding of a secret telegram from German Foreign Minister Arthur Zimmermann to Mexico, proposing a military alliance against the United States in exchange for territorial concessions, such as the return of Texas, New Mexico, and Arizona to Mexico. The Zimmermann Telegram provoked outrage and alarm across the United States, further eroding public trust in Germany and increasing pressure on President Wilson to take decisive action. While it strengthened the case for intervention among some Americans, others remained cautious, not wanting to be drawn into a distant and costly conflict.

Sinking of the Lusitania

The sinking of the British passenger liner Lusitania by a German submarine resulted in the deaths of 1,198 passengers, including 128 Americans. This event significantly escalated tensions between the United States and Germany, although President Woodrow Wilson refrained from immediate military action, maintaining a stance of neutrality. While the sinking of the Lusitania increased anti-German sentiment in the United States, it did not immediately push America into the conflict. Instead, it fueled debates over the nation's role in the war, with some advocating for intervention to protect American interests and others preferring to maintain neutrality.

Established by President Wilson to generate public support for the war, the Committee on Public Information employed various propaganda techniques, including posters, pamphlets, and speeches, to shape public opinion and foster a sense of national unity. The Committee on Public Information played a significant role in mobilizing public opinion in favor of the war effort. However, its methods also sparked debates over censorship and the manipulation of public sentiment.

Committee on Public Information

The overthrow of the Tsarist autocracy in Russia led to a series of revolutions culminating in the Bolshevik seizure of power. The Bolsheviks, led by Vladimir Lenin, withdrew Russia from World War I, signing the Treaty of Brest-Litovsk with Germany. Initially greeted with cautious optimism by some as a potential ally against Germany, the Russian Revolution soon became a source of concern and uncertainty. The rise of Bolsheviks and the withdrawal of Russia from the war fueled fears of communist revolution spreading to other countries and complicated America's stance on the conflict.

Russian Revolution

President Wilson's address to Congress outlined his vision for a post-war world based on principles such as self-determination for nations, open diplomacy, disarmament, and the establishment of a League of Nations. Wilson's Fourteen Points Speech garnered widespread international attention and raised hopes for a just and lasting peace

Wilson's 14 Points Speech

Passed in response to fears of espionage and subversion, the Espionage Act granted the government broad powers to prosecute individuals engaged in activities deemed detrimental to the war effort, including the distribution of anti-war literature and the obstruction of military recruitment. The Espionage Act marked a significant expansion of government authority and a crackdown on dissent, leading to the suppression of civil liberties and the prosecution of anti-war activists and labor organizers. While some Americans supported the law as necessary for national security, others denounced it as a violation of constitutional rights

Espionage Act

Enacted to address the shortage of military manpower, the Selective Service Act authorized the conscription of men into the armed forces through a national draft system. While the Selective Service Act was instrumental in rapidly expanding the size of the military, it also stirred controversy and resistance among those opposed to compulsory service. Some viewed conscription as an infringement on individual liberties.

Selective Service Act

The Spanish flu pandemic, which swept through military camps and trenches during World War I, caused widespread illness and death among soldiers. The close quarters and poor living conditions of military encampments facilitated the rapid spread of the virus. The influenza pandemic showed the vulnerability of troops and highlighted the urgent need to end the war. The staggering death toll and the strain on military resources intensified pressure on the government to seek a swift resolution to the conflict. It ultimately greatly shortened the duration of the war.

Influenza Pandemic and its Impact on U.S. Troops

Created to oversee wartime production and allocation of resources, the War Industries Board coordinated industrial mobilization efforts, regulated production levels, and encouraged efficiency in war-related industries. While the War Industries Board played a crucial role in mobilizing the nation's industrial capacity for war, its centralized control and government intervention in the economy sparked debates over the balance between government authority and private enterprise. Some saw it as a necessary measure to ensure wartime production, while others criticized it for stifling innovation and competition.

War Industries Board

Amended to the Espionage Act, the Sedition Act criminalized disloyal or abusive language directed at the government or the military, effectively suppressing dissent and anti-war sentiments. The Sedition Act triggered a wave of arrests and prosecutions targeting anti-war activists, labor organizers, and ethnic minorities, exacerbating fears of government overreach and violating civil liberties.

Sedition Act

The Treaty of Versailles was the peace treaty that officially ended World War I, imposing harsh terms on Germany and laying the groundwork for the post-war world order. It established the League of Nations, an international organization aimed at promoting peace and collective security. While initially celebrated as a triumph of diplomacy, the treaty's punitive measures and the United States' failure to join the League of Nations sparked controversy and debate.

Treaty of Versailles

Launched as the final Allied offensive on the Western Front, the Meuse-Argonne Offensive aimed to break through the German lines and force an end to the war. It was the largest American military operation of the war, involving over a million American troops. The Meuse-Argonne Offensive was a pivotal moment in the war, resulting in significant casualties but ultimately contributing to the Allied victory.

Meuse - Argonne Offensive

The League of Nations was established as an international organization aimed at maintaining peace and preventing future conflicts. It was a key component of President Wilson's vision for a post-war world order, however the United States ultimately did not join due to congressional opposition, reflecting deep-seated reservations about international entanglements and a desire to maintain national sovereignty. The decision highlight the enduring debates over America's role in global affairs and the balance between national interests and international cooperation.

Formation of the League of Nations

Rather than a surrender, an armistice agreement was signed between the Allies and Germany to mark the end of World War I hostilities. The armistice brought an end to four years of brutal warfare. The news of the armistice was met with joy and relief across the country. However, it still to this day prompts reflection on the toll of the war and the loss of human life.
