Abraham Lincoln was a former President of the United States.
It is unknown when or how long he served as president, though he may have served much like his real-world counterpart as the 16th president of the USA. He was eventually succeeded by Harry S. Truman and John F. Kennedy, along with whom there was a wax model made of them in Canton, Ohio.
A Leshi uses Abraham Lincoln's form to attack and kill a man named William Hill. Sam and Dean Winchester initially suspect a ghost attack, but soon discover the true culprit. The Leshi had used the hat of the wax model to take on Abraham's form, and did this because a leshi only devoured the blood of its worshipers, and those like Abraham had fans. Sam manages to decapitate the Leshi in the end.
Rowena mentions that she promised Lincoln "a fun night at the theatre", however, Lincoln's assassination changed things. She uses this incident as a reason for Sam to break his promise to wait for Dean in their trip to Limbo.
- Lincoln was assassinated on April 14, 1865 at Ford's Theatre by John Wilkes Booth. The motive was an act of rebellion against Lincoln's abolition of slavery. The slaves were usually Africans or African Americans. Despite Lincoln's demise, slavery is no longer legal in the United States.
