Abraham Lincoln, often known as Honest Abe, the Rail-Splitter, or the Great Emancipator, was the 16th President of the USA (1861–65), who maintained the Union throughout the American Civil War and brought about the liberation of slave individuals in the United States.

Among American heroes, Lincoln holds a distinctive appeal both for his compatriots and those from various nations.

His importance remains and rises, owing to his charisma as a champion for freedom. The Union, in his opinion, was worth preserving not just for its own sake, but also because it reflected an ideal, the suitable of self-government.

In the latest days, the political aspects of Lincoln's personality, particularly his racial beliefs, have come understudy, as researchers strive to search him a valuable addition of inquiry. The Lincoln Memorial in Washington, D.C. was erected to him on May 30, 1922.
