* "O Captain! My Captain!" This is arguably his most famous and iconic poem about Lincoln, written shortly after Lincoln's assassination. It uses the metaphor of a ship and its captain to represent the nation and its leader, mourning Lincoln's death and celebrating his legacy.
* "When Lilacs Last in the Dooryard Bloom'd" This long, complex poem is a meditation on Lincoln's death, weaving together themes of nature, death, grief, and hope. It uses the imagery of lilacs, a mourning dove, and a star to symbolize Lincoln's death and the nation's grief.
* "This Dust Was Once the Man" This poem, also written shortly after Lincoln's death, focuses on the physicality of Lincoln's death, the dust that remains of his body, and the powerful impact his life had on the nation.
* "Hush'd Be the Camps To-Night" This poem, written in the midst of the Civil War, expresses Whitman's grief over the losses of the war and his hope for a lasting peace under Lincoln's leadership.
* "Democracy" While not explicitly about Lincoln, this poem celebrates democratic ideals and the principles that Lincoln embodied as President. Whitman's belief in equality and the common man resonates with Lincoln's own beliefs and actions.
In addition to these poems, Whitman wrote numerous other pieces about Lincoln, including letters, articles, and even a collection of poems titled "Drum-Taps" which was dedicated to the war effort and Lincoln's leadership. He also attended Lincoln's funeral and wrote about his observations in his journals.
Whitman's poetry about Lincoln reflects his deep admiration for the President, his grief over his death, and his profound belief in the power of democracy and the importance of a unified nation.
