World War I transformed Texas, propelling the state into a new era of economic and social change. From military training camps to oil production, Texas played a crucial role in the American war effort, solidifying its strategic importance on the national stage.
The war's impact extended beyond the battlefield, reshaping Texas's economy, society, and culture. Agriculture and industry boomed, while labor shortages created new opportunities for women and minorities, setting the stage for significant social changes in the years to come.
U.S. Involvement in World War I

Catalysts for U.S. Entry
Several events pushed the United States from neutrality into war:
- Unrestricted submarine warfare: Germany's policy of sinking civilian ships, including the Lusitania in 1915 (killing 1,198 passengers, including 128 Americans), turned American public opinion against Germany.
- The Zimmermann Telegram: In January 1917, British intelligence intercepted a secret German message proposing a military alliance with Mexico. Germany promised to help Mexico reclaim territory lost in the Mexican-American War (Texas, New Mexico, Arizona). This hit especially close to home for Texans.
- Wilson's ideological case: President Woodrow Wilson asked Congress for a declaration of war in April 1917, framing it as a mission to "make the world safe for democracy."
Texas's Strategic Role
Texas's geography, resources, and existing military infrastructure made it a natural hub for the war effort.
- Military training camps were established across the state. Fort Sam Houston in San Antonio became one of the largest training centers in the country, and Camp Logan was set up in Houston to prepare soldiers for deployment.
- The Port of Galveston served as a key embarkation point, shipping troops and supplies to Europe.
- Texas's oil fields provided essential fuel for Allied vehicles, ships, and aircraft. The state was already emerging as a major energy producer, and wartime demand accelerated that growth dramatically.
Texan Contributions to the War Effort
Military Units and Operations
Tens of thousands of Texans served in the armed forces, and several units became closely identified with the state.
- The 36th Infantry Division (the "Texas Division"), composed primarily of Texas and Oklahoma National Guard units, saw significant combat in France.
- The 90th Infantry Division (the "Tough 'Ombres") included many Texans and fought in two of the war's major offensives: St. Mihiel and the Meuse-Argonne. The 359th Infantry Regiment, part of the 90th Division, was composed largely of Texans and distinguished itself in combat.
- Texas women served as nurses in military hospitals both stateside and overseas, providing critical medical care to wounded soldiers.

Notable Individuals
- Captain Edgar Gardner Tobin of San Antonio became one of America's famous fighter pilots, earning the title of "ace" by shooting down at least five enemy aircraft. His success in aerial combat inspired other Texans to volunteer for the air service.
- David E. Hayden, a Navy corpsman from Texas, received the Medal of Honor for repeatedly risking his life to rescue wounded Marines under heavy fire. His actions exemplified the bravery of Texan servicemembers throughout the war.
Economic Impact of World War I on Texas
Agricultural and Industrial Growth
Wartime demand supercharged multiple sectors of the Texas economy:
- Cotton was essential for military uniforms, tents, and equipment. Prices and production soared, bringing a windfall to Texas farmers and rural communities.
- The cattle industry expanded as ranchers grew their herds to supply beef for troops at home and abroad.
- Oil production surged to meet the military's enormous fuel needs. New oil fields and refineries sprang up across the state, deepening Texas's role as a national energy supplier.
- Shipbuilding along the Gulf Coast expanded rapidly, creating new jobs in coastal cities like Galveston and Corpus Christi.
Labor Market Changes
- Military-related industries grew quickly in urban areas, especially Dallas and Houston, where factories retooled to produce weapons, ammunition, and other war supplies.
- With so many men enlisting, labor shortages drove up wages and opened doors for workers who had previously been shut out. Women entered traditionally male-dominated fields like manufacturing and transportation. African Americans and Hispanic Texans found new employment opportunities in urban centers, beginning a slow but meaningful shift in the state's workforce.

Social and Cultural Change in Texas
Shifting Identities and Discrimination
The war effort promoted a strong sense of national unity and patriotism, but that came with a darker side.
- Texans embraced their American identity more strongly, sometimes at the expense of local or ethnic affiliations.
- German-American communities in Texas faced intense pressure to prove their loyalty. Some German Texans anglicized their names or stopped speaking German in public. German-language newspapers and schools were shut down or censored. This was a painful chapter for communities that had been part of Texas for generations.
Public Health and Social Movements
- The influenza pandemic of 1918โ1919 devastated Texas, killing thousands of civilians and soldiers alike. Public spaces were temporarily closed, and the crisis exposed serious gaps in the state's public health infrastructure.
- Women's wartime work strengthened the case for women's suffrage in Texas. Their increased economic independence and public visibility made it harder to argue they shouldn't vote. Texas became the first Southern state to ratify the 19th Amendment in 1919.
- African American veterans who had experienced relatively more equal treatment in France returned home unwilling to accept Jim Crow. Many became active in civil rights efforts, and organizations like the NAACP grew their presence in Texas during this period.
Post-War Societal Changes
- The war accelerated urbanization as Texans moved to cities for industrial jobs. This rural-to-urban migration reshaped the state's demographic landscape and altered traditional social structures.
- Post-war economic readjustment brought real tension. Workers who had gained ground during the war fought to keep those gains, leading to strikes and labor disputes. Racial violence, including lynchings, increased in some areas as returning soldiers and changing social dynamics challenged existing hierarchies. The transition to peacetime was anything but smooth.
