The civil war came to an end when a big turning point Lincoln did the emancipation proclamation when freed slaves in the south if they can get to the north. With England not joining the Confederacy, the lost men, military and strength. The war ended in Spring, 1865. Robert E. Lee surrendered the last major Confederate army to Ulysses S. Grant at Appomattox Courthouse on April 9, 1865.

probably E, because it could lead to war, plus this goes more along the lines of world affairs.
