Some notable U.S. presidents include George Washington, Abraham Lincoln and Franklin D. Roosevelt. While Washington served at the infancy of the country, Lincoln and Roosevelt both served during times of war and crisis.
George Washington, the first president, served from 1789 until 1797. He was unanimously elected twice. His decisions and choices as commander-in-chief set the standard for many modern-day traditions. He gave the first State of the Union address in 1790.
The 16th president, Abraham Lincoln, served from 1861 until his assassination in 1865. After election, he was thrust into the crisis of the Civil War. During the war, he felt it necessary and just to emancipate the slaves in the South, and he made repeated trips to visit troops and keep morale high. Following the war, his plans for the Southern Reconstruction never made it to light, as he was gunned down at Ford's Theater by John Wilkes Booth, a Southern sympathizer.
The longest serving president, Franklin D. Roosevelt, came into office during the Great Depression and died in office in the final months of World War II. Roosevelt served from 1933 until 1945, and he is the only president elected four times. His New Deal policies helped guide the country out of economic depression.
