Abraham Lincoln and Theodore Roosevelt are considered two of the greatest presidents the United States of America has ever had. Honest Abe Lincoln is known for his role in abolishing slavery and reunifying the North with the South to end the Civil War. Lincoln began his presidency on March 4, 1861, and was assassinated on April 15, 1865 (compare Lincoln vs. Roosevelt) abruptly ending his term. "Teddy Roosevelt" was known as a valiant explorer and a great environmentalist. He became president on September 14, 1901 and left on March 4, 1909. Both of these men achieved great things during their presidential terms that not only changed the United States, but created ideas and values ​​on which this country was built. Abraham Lincoln and Theodore Roosevelt were both great presidents, but in different ways. Abraham Lincoln and Theodore Roosevelt were both effective peacemakers, but Lincoln focused on creating peace in America while Theodore Roosevelt focused on foreign countries. When Lincoln became president, Northern and Southern states erupted into conflict over issues such as states' rights and slavery (“Causes of the Civil War”). While the North and South fought, Lincoln not only fought to help the North win, but sought to reunite the North and South while abolishing slavery. When the Civil War was won by the North, Lincoln avoided any hatred towards the people of the South and encouraged the people of the North to accept him again. In a conversation with a woman who believed that Southerners should be "destroyed," Lincoln told the woman "...am I not destroying my enemies when I make them friends?" (Lincoln quote dated 10/19/07). Unfortunately, Lincoln never had the chance to oversee the meeting...at the heart of the paper...the process of accepting African-Americans into American culture and way of life within the nation.
