World War II transformed Texas from 1939 to 1945. The state became a hub for military training, oil production, and manufacturing. Over 750,000 Texans served in the armed forces, while the home front saw economic growth and social changes. The war's impact on Texas lasted well beyond 1945. The GI Bill, suburbanization, and industrial expansion reshaped the state. Civil rights movements gained momentum, challenging segregation. Texas emerged as a major center of business, technology, and aerospace in the post-war era.
