He was definitely one of the greatest American presidents. He led the country during its most difficult and volatile time,the Civil War. He put an end to slavery in the US. Even though he faced great personal difficulties and trials during his time as President (among them, his young son's death), he worked tirelessly for his country. He was assassinated at the time of his greatest triumph, just days after the end of the Civil War. He is remembered as someone who gave everything he had to his country.
