Abigail Adams was the wife of John Adams, second President of the United States and the mother of the sixth President, John Quincy Adams. Her letters and memoirs of the Revolutionary era are considered to be major historical documents.
Abraham Lincoln was an American political leader during the 19th century. Rising from humble beginnings, Lincoln was elected as the 16th President of the United States in 1860. Lincoln's election prompted the secession of several Southern states and eventually the beginning of the American Civil War. Lincoln served as president and commander-in-chief throughout most of the conflict before an assassin's bullet tragically cut his life short on April 15, 1865.
