Question

i need help with my intro and outline for a paper on how/why MLK Jr. changed the world/how/why he is important

Answer 1

Have you gathered research material? It doesn't sound like a biography so don't organize it chronologically.
You'll want to decide your answers to the question about his importance. List at least 3. Then sort your information into those sub topics. The infor should support the statements you make in the sub-topic areas.

Write the middle first. Then the introduction can just introduce what you have written.
