Lincoln and Madison are two of the most influential figures in American history. Abraham Lincoln was the 16th President of the United States, serving from 1861 to 1865, and is best known for leading the country through the Civil War and abolishing slavery. James Madison was the fourth President of the United States, serving from 1809 to 1817, and is widely regarded as the 'Father of the Constitution' for his role in drafting the document that established the framework for the United States government. Both men were also instrumental in the creation of the Bill of Rights.
