Answer: Many historians consider Abraham Lincoln to be the most important American president.
Explanation:
This attitude is established in the American public, a large number of citizens of the United States have such an opinion, so it is not just the profession's views. Lincoln today often presents himself as a saint, a person who gave his life for others to be free, alluding to the struggle against slavery. Link's legacy is thus measured today in what is most important to every human being, which is, of course, such precious freedom.

Lincoln also strengthened the office of president since, in difficult times, he made some decisions on his own without first consulting with Congress, and those decisions turned out to be the right ones.
