The Emancipation Proclamation

The Emancipation Proclamation

The Emancipation Proclamation enabled African-Americans, both free blacks and escaped slaves, to join the Union Army. About 190,000 volunteered, further enhancing the numerical advantage the Union armies enjoyed over the Confederates, who did not dare emulate the equivalent manpower source for fear of fundamentally undermining the legitimacy of slavery. Emancipated slaves mostly handled garrison duties, and fought numerous battles in 1864–65. European immigrants joined the Union Army in large numbers, including 177,000 born in Germany and 144,000 born in Ireland. The railroad industry became the nation's largest employer outside of agriculture. The American Civil War was followed by a boom in railroad construction, which contributed to the Panic of 1873.

Slavery for the Confederacy's 3.5 million blacks effectively ended when Union armies arrived. They were nearly all freed by the Emancipation Proclamation. Slaves in the border states and those located in some former Confederate territory occupied prior to the Emancipation Proclamation were freed by state action or (on December 18, 1865) by the Thirteenth Amendment. The full restoration of the Union was the work of a highly contentious postwar era known as Reconstruction. The war produced about 1,030,000 casualties (3% of the population), including about 620,000 soldier deaths—two-thirds by disease. The war accounted for roughly as many American deaths as all American deaths in other U.S. wars combined.
