Mahatma Gandhi is most famous for his successful application of non-violent methods, like civil disobedience. He was a source of inspiration for many world leaders including Martin Luther King Jr.; and in India, he is unofficially known as the Father of the Nation.
John Smith
John Smith was an original settler and leader of the Jamestown colony. His early contact with the neighboring Powhatan tribe would lead to the success of the colony.
Early in the settlement of Jamestown, Smith was captured by the Powhatan. This capture would eventually produce the story of his capture and being saved by Pocahontas, the chiefs' daughter. During the second year of the colony, Smith became the president or governor of the colony. He used this power to negotiate, sometimes forcibly, with the Powhatan for corn which kept the colony safe from starvation. Smith was wounded by an explosion and was convinced to give up leadership and return to England.
On June 29, 1947, as the first president to address the National Association for the Advancement of Colored People (NAACP), Harry Truman pledges his support for upholding the civil rights of all Americans.
