The North was also interested in denying the South imports and other aid from foreign countries, especially from Great Britain.

Freed slaves still could not fight, but Congress hoped the act would give them an incentive to flee toward advancing Union troops. No longer hopeful of luring the South back into the Union, Congress also put an end to slavery in Washington, D.C., and banned slavery in the territories.
