Martin Luther King, who is known to the world as the ambassador of peace, has been remembered all the time, though he has died for a few decades. I have learned an artcile about him lately, his great speech I Have a Dream impressed me so much. Martin described his great wish of all the people could be treated equal, no matter what color they were. He appealled people to join his team and made the world a peaceful place. His speech inspired so many people at that time and still affects the world today. There is no doubt that Martin is a great person, what he brings to the world will never fade away.
