Events and Accomplishments of Theodore Roosevelt’s Presidency President Roosevelt served through most of the first decade of the 1900s. He was determined to build a canal across Panama. America aided Panama in gaining independence from Colombia. The U.S. then created a treaty with the newly independent Panama to gain the canal zone in exchange for $10 million-plus annual payments. The Monroe Doctrine is one of the keystones of American foreign policy. It says that the western hemisphere is off-limits to foreign encroachment. Roosevelt added the Roosevelt Corollary to the Doctrine. This stated that it was the responsibility of America to intervene with force if necessary in Latin America to enforce the Monroe Doctrine. This was part of what became known as 'Big Stick Diplomacy'. From 1904-05, the Russo-Japanese War occurred. Roosevelt was the mediator of peace between the two countries. Due to this, he won the 1906 Nobel Peace Prize. While in office, Roosevelt was known for his progressive policies. One of his nicknames was Trust Buster because his administration used existing antitrust laws to fight against corruption in the railroad, oil, and other industries. His policies concerning trusts and labor reform were part of what he called the "Square Deal." Upton Sinclair wrote about the disgusting and unsanitary practices of the meat packing industry in his novel The Jungle. This resulted in the Meat Inspection and the Pure Food and Drug Acts in 1906. These laws required the government to inspect meat and protect consumers from food and drugs that might be dangerous. Roosevelt was well-known for his conservation efforts. He was known as the Great Conservationist. During his time in office, over 125 million acres in national forests were set aside under public protection. He also established the first national wildlife refuge. In 1907, Roosevelt made an agreement with Japan known as the Gentleman's Agreement whereby Japan agreed to slow the immigration of laborers to America and in exchange, the U.S. would not pass a law like the Chinese Exclusion Act. Post-Presidential Period Roosevelt did not run in 1908 and retired to Oyster Bay, New York. He went on a safari to Africa where he collected specimens for the Smithsonian Institute. Even though he promised not to run again, he sought the Republican nomination in 1912. When he lost, he formed the Bull Moose Party. His presence caused the vote to be split allowing Woodrow Wilson to win. Roosevelt was shot in 1912 by a would-be assassin but was not seriously injured. He died on January 6, 1919, of a coronary embolism. Historical Significance Roosevelt was a fiery individualist who embodied the American culture of the early 1900s. His conservationism and willingness to take on big business are examples of why he is considered to be one of the better presidents. His progressive policies set the stage for important reforms of the 20th century.
