Dred Scott v. Sandford: Dred Scott tried to sue his master for freedom but the supreme court reconfirmed lack of civil rights for blacks. Dred Scott could not sue his master because he wasn't a citizen.
The Election of 1860: Lincoln, Douglas, Bell, and Breckenridge all ran for presidency. This made the country split on opinions on slavery. The election of Lincoln without a single southern vote led to the south seceding.
I don't want them to have these rights!
Anaconda Plan: The union made this plan at the start of the war, they set a blockade and cut off confederates from getting supplies. This led them to struggle to get the guns and ammo and everything else they needed.
Surrender at Appomattox: At a Village in Virginia, General Lee (confederate general) surrendered to the union commanded under General Grant. This ended the war and left the union victorious.
Black Codes: Restricting blacks new rights, labors contracts, curfews, and marriage laws.
Yay our rights and all this nice stuff, but I want them in full strength!
Jim Crow Laws: legislation was passed in southern states after reconstruction ended to keep the whites and the blacks separated from each other.
