Some noteworthy American presidents include Thomas Jefferson, Franklin D. Roosevelt and Ronald Reagan. All three presidents saw major policy accomplishments during their tenures. Additionally, all three presidents served multiple terms.
Thomas Jefferson, who served from 1801 until 1809, oversaw the purchase of the Louisiana Territory from the French. This purchase immediately greatly increased the size of the country and prompted the American migration west. He also worked to keep the country out of the European war between France and Great Britain, striving to keep the country's neutrality.
Franklin D. Roosevelt served a record four terms in office from 1933 through 1945 and guided the country through the Great Depression and World War II. His New Deal policies helped aid the country's economic struggles during the depression. Although he tried to keep the country out of World War II, he urged Congress to declare war on Japan following the bombing of Pearl Harbor. Before his death in 1945, he worked closely with Winston Churchill and Joseph Stalin to prepare for a post-war Europe.
Ronald Reagan became president in 1981 and served until 1989. He met with Soviet Union president Mikhail Gorbachev starting in 1985, which prompted the beginning of the end of the Cold War. He urged Gorbachev to remove the Berlin Wall and worked to come to multiple arms and nuclear weapons treaties with the Soviets.
