About how much time has passed between the signing of the emancipation proclamation and Dr. Kings speech

President Abraham Lincoln issued the Emancipation Proclamation on January 1, 1863, whereas Dr. King gave his famous "I Have A Dream" speech on August 28, 1963. Therefore, over 100 years had passed between the two events, and while slavery had been formally abolished for that duration, the Civil Rights movement showed that there was still tremendous work to be done in ensuring equality and fair treatment for African Americans.
