The American Civil War lasted for just four years, from 1861-1865 and it is often also known as the War Between the States. It was the event where 11 Southern States that supported slavery declared their succession from the United States, and announced the formation of the Confederate States of America.
It chose as their leader Jefferson Davis, and they declared war on the remaining states in the United States, referred to as The Union.
The results of the Civil War was the decisive defeat of the Confederate States of America, and their eventual resumption of their status in the United States. The time period directly after the Civil War was known as the Reconstruction, a time marked by turmoil, violence and a lot of conflict and controversy. The Reconstruction Era was not a peaceful time, there were a large number of people that tried to take advantage of the weakened South.
The biggest result was the end to Slavery. The 13th Amendment called for the abolishment of Slavery, and it was in support of President Lincoln’s Emancipation proclamation.
In addition, the 14th and 15th Amendments to the Constitution were also passed by Congress and ratified by states, becoming law.
The 13th Amendment effectively made law the ending of slavery across the United States. The 14th Amendment was enacted that said that Federal Legal Protection is available to all United States citizens, regardless of what race, color or creed they are. This was a new policy and came as part of the aftermath and results of the Civil War.
Finally, the last Amendment to the Constitution that was a result of the Civil War was the 15th Amendment. The 15th Amendment abolished all restrictions on voting and said that all U.S. Citizens would be able to vote no matter what race they were.
Despite the ending of the Civil War 1865, it took another 12 years for most states to successfully make the transition back into the United States.
This aftermath is called the Reconstruction, and most historical scholars agree that the Reconstruction was ended finally by the Compromise of 1877, when Federal Troops were removed from the South and Rutherford B. Hayes was elected as U.S. President.
