The Fourth Party System and the Fifth Party System

The Fourth Party System, 1896 to 1932, retained the same primary parties as the Third Party System, but saw major shifts in the central issues of debate. This period also corresponded to the Progressive Era, and was dominated by the Republican Party.

The era began in the severe depression of 1893 and the extraordinarily intense election of 1896. It included the Progressive Era, World War I, and the start of the Great Depression. The Great Depression caused a realignment that produced the Fifth Party System, dominated by the Democratic New Deal Coalition until the 1960s.

The central domestic issues concerned government regulation of railroads and large corporations ("trusts"), the protective tariff, the role of labor unions, child labor, the need for a new banking system, corruption in party politics, primary elections, direct election of senators, racial segregation, efficiency in government, women's suffrage, and control of immigration. Foreign policy centered on the 1898 Spanish-American War, imperialism (and Banana Wars), Dollar Diplomacy, the Mexican Revolution, World War I, and the creation of the League of Nations. Dominant personalities included presidents William McKinley, Theodore Roosevelt and Woodrow Wilson, and three-time presidential candidate William Jennings Bryan.
