Which of the following best explains the emancipation proclamation?

It started that all slaves in the Confederate States should be free

Explanation:

The Emancipation Proclamation actually consisted of two executive orders given by Abraham Lincoln during the course of the Civil War. The first order was issued on September 22, 1862, and stated that all slaves in rebelling states would be freed as of January 1, 1863, if those states did not agree to return to the Union. Though many argue that the proclamation did not change the day to day lives for most slaves living in Confederate states, it was successful in changing the general focus of the war. Rather than simply being a military conflict with the purpose of preserving the Union, the focus of the war came to be about abolishing slavery.
