Iwill give brainliest to first correct what are the causes and effects of the battle of gettysburg? i only need 4 causes and effects!

The American Civil War had lots of negative effects to the South...A very important cause of the cause of the American Civil War was the election of Abraham Lincoln. Lincoln wanted to abolish slavery and the Southerners did not want to be ruled by an anti-slavery Northerner. 

Another cause and effect was the Kansas-Nebraska act. This act was brought up to admit the states in
the Louisiana Purchase to be admitted as union states. Kansas objected to this because it was a pro-slavery state... 

The Reconstruction was a movement in the time period between 1865 and 1869 that aimed to integrate the seceded states back into the nation and make sure they obey the laws of the Union this time. The Reconstruction also helped rebuild and repair the towns and buildings in the South.

The most important effect of the Civil War was the Emancipation Proclamation in 1863. Abraham Lincoln declared all slave states in rebellion.
