In late September 1901, newspaper headlines across the United States began to shift from shock and grief over President William McKinley’s assassination to intense interest in his unexpected successor. Theodore Roosevelt, only forty-two years old when he took the oath of office on September 14, became the youngest person ever to serve as president of the United States.
Roosevelt inherited a country in mourning, but his forceful personality, reputation for reform, and youthful energy quickly created a sense that a new political era had begun. Unlike presidents who arrived in office after a lengthy national campaign, Roosevelt assumed the nation’s highest office suddenly, carrying the immediate responsibility of preserving public confidence and national unity.
Although John F. Kennedy would later become the youngest person elected president at age forty-three, Roosevelt remains the youngest individual ever to serve in the office. Over the next seven years, he would broaden the public role of the presidency and lead an administration remembered for antitrust enforcement, conservation, consumer protection, and a more active American role in world affairs.
