Martin Luther King Jr's speech and Nelson Mandela's speech -compare and Contrast

I have to write a compare and contrast essay on Martin Luther King Jr's speech and Nelson Mandela's speech and i am having trouble with starting the essay especially the 1st paragraph Help please!!

I'm assuming you're referring to Martin Luther King Jr's famous speech called, I Have a Dream, and Nelson Mandela's 1994 inaugural address. These each have strong sentiments on brotherhood, peace, and racial justice. One is more spiritual, but I'll leave it up to you to read through them both, taking notes on what stands out to you the most. If you are moved at all by them, it should be extremely easy to begin.

Yes, the essay really has to begin with a thought that arises in your mind as you read these works. You have to have confidence in you idea you have. Do you notice an similarity between them that seems UNCANNY? How about a similarity that is meaningful... or a difference that shows one of them to have known something the other did not know.

Your job is to read these, and watch the videos if available, and really experience this part of history so that you feel the urge to write all kinds of first paragraphs.

What ideas have arisen in your mind about these so far? What have you noticed?
