1 Abraham Lincoln
Abraham Lincoln is the highest-ranking American President of all time. He was the 16th President from 1861 to 1865. He led the Union during the civil war and, above all, began the process of abolishing slavery.
He laid the foundations for the abolition of slavery by promulgating the Emancipation Proclamation in 1863, which changed the status of slaves in the South to liberate peoples. Its mission was to add the 13th amendment to the Constitution, which would make slavery officially illegal in the United States. Unfortunately, the Constitution was not adopted until after Lincoln’s assassination in 1865. A number of different polls show that Lincoln is the most admired American President of all time.
