Located adjacent to the Hall of Presidents, in Liberty Square, is the Liberty Tree. In Boston, a large elm tree at the corner of Essex Street and Orange Street became known as the Liberty Tree. The tree was a popular rallying point beginning in 1765 after the passage of the Stamp Act.

A "liberty pole" was installed nearby with a flag that could be raised above the tree to summon the townspeople to a meeting.

When the Stamp Act was repealed in 1766, townspeople gathered at the Liberty Tree to celebrate. They decorated the tree with flags and streamers, and when evening fell, hung dozens of lanterns from its branches.

"After the assassination of President McKinley, Theodore Roosevelt (September 14, 1901-March 4, 1909) went to power. Roosevelt helped to industrialize the US’s economy by introducing new labor laws, placing regulations to curb the power of large corporations such as Standard Oil, and the railroad contractors. With the Pure Food and Drug Act, which gave birth to the present Food and Drug Administration, he also enhanced consumer protection and created the first national parks. Roosevelt followed an aggressive foreign policy, negotiating the beginning of the war between Russia and Japan and creating the Canal of Panama. He strengthened the American Navy by journeying battleships throughout the globe to make friendly courtesy visits (Great White Fleet). These ‘courtesy visits’ made sure the world should see the new American Naval power. Today, we can thank him for promoting child labor laws, women’s rights, an 8-hour working day, and building a new image of masculinity that combined education, bodily strength, and rugged individualism."

"The longest-serving President of the United States was Franklin Delano Roosevelt (FDR) (March 4, 1933-April 12, 1945). Elected during the troubled times of the Great Economic Depression, he held the oval office from 1933 to only months before World War II ended in 1945. During his presidential tenure, he planned to extend the federal government’s functions. Depression-era federal programs such as Social Security, implemented during FDR’s tenure, still exist, offering the most susceptible nation with fundamental economic protection. The U.S. also took on a prominent fresh role in global affairs because of the conflict, a stance it still holds. Using American convoy strategies and superior technology reduced the efficiency of German submarines in the North Atlantic, thanks to his priority on military innovation. The US and the allies also gained air superiority because of advanced fighter planes over Axis forces. Because of his economic, diplomatic, and defense policies, many consider him one of the best presidents America ever had."
