Final answer:
Approximately 100 years passed between the signing of the Emancipation Proclamation on January 1, 1863, and Dr. Martin Luther King Jr.'s "I Have a Dream" speech on August 28, 1963.
Step-by-step explanation:
About how much time has passed between the signing of the Emancipation Proclamation and Dr. King's speech? The Emancipation Proclamation was signed by President Abraham Lincoln on January 1, 1863, during the Civil War, proclaiming that all slaves in Confederate territory were to be forever free. Dr. Martin Luther King Jr.'s famous "I Have a Dream" speech was delivered on August 28, 1963, during the March on Washington for Jobs and Freedom. Therefore, approximately 100 years passed between the two historic events.
