Walt Whitman is often called the poet of American democracy. He lived during the American Civil War, and he admired President Abraham Lincoln very much.
    Whitman was the first American poet who wrote about true equality among all people. In a poem called "Song of Myself he compared himself to all other people, and he found no difference. He wrote:
    "... every atom belonging to me... Belongs to you."
    In the same poem Whitman spoke up for women. He wrote:
    "The Female equally with the Male I sing."
    He also wrote:
    "In the faces of men and women I see God." and "A great city is that which has the greatest men and women."
    Whitman understood war and the result of war. He worked in a hospital, taking care of wounded men. In a description of northern soldiers who had returned from prisons in the south he wrote: "The sight is worse than any sight of battlefields or any collection of wounded, even the bloodiest." In Whitman’ s words: "The real war will never get in the books."
    Whitman was the first important American poet to write about ordinary people, using ordinary language.
