Well with this question it would have to come from your thoughts, and who you would pick.
The nationalist lead for me I would pick is Nelson Mandela. Mandela was a hero, and a true inspiration to the world. He believed everything should be equal and that color shouldn't define who a person is. Mandela sacrificed a lot such as being sentenced to 27 years in prison for his actions to overthrow the government. Through all that he suffered he never felt the need to get revenge. His heart was full for the people. For his bravery, love, compassion, and heroism I would choose him.
