Answer:
The best president in American history was, according to many, Abraham Lincoln.
Step-by-step explanation:
Abraham Lincoln officiated from 1861 to 1865 as the 16th President of the United States of America. He was the first Republican president.
His presidency is considered to be one of the most significant in the history of the United States: his election led eleven of the slave-holding southern states, to withdraw from the Union and form their own confederation, the Confederate States of America. Lincoln led the remaining northern states through the resulting Civil War. He enforced the restoration of the Union and successfully abolished slavery in the United States. Under his term, the country made its way to the centrally governed, modern industrial nation that is today, laying the foundation for its rise to world power in the 20th century.
