US and Virginia History SOL Practice Test

The Progressive Movement was a period of broad reforms aimed at weakening corporate power, expanding democracy, and improving social welfare. When the United States entered World War I, in 1917, national priorities shifted from domestic reform to war mobilization and national security. Wartime needs brought a surge of centralized government power, wartime legislation, and a focus on victory, which redirected energy away from ongoing reform campaigns. After the war, the political mood turned more conservative and disillusioned with reform efforts, signaling the end of the era. So, the conflict that marks the end of the Progressive Movement is World War I.
