Theodore Roosevelt (born October 27, 1858, New York, New York, U.S.—died January 6, 1919, Oyster Bay, New York) was the 26th president of the United States (1901–09) and a writer, naturalist, and soldier. He expanded the powers of the presidency and of the federal government in support of the public interest in conflicts between big business and labor and steered the nation toward an active role in world politics, particularly in Europe and Asia. He won the Nobel Prize for Peace in 1906 for mediating an end to the Russo-Japanese War (1904–05), and he secured the route and began construction of the Panama Canal (1904–14).

The early years

Roosevelt was the second of four children born into a socially prominent family of Dutch and English ancestry; his father, Theodore Roosevelt, Sr., was a noted businessman and philanthropist, and his mother, Martha Bulloch of Georgia, came from a wealthy, slave-owning plantation family. In frail health as a boy, Roosevelt was educated by private tutors. From boyhood he displayed intense, wide-ranging intellectual curiosity. He graduated from Harvard College, where he was elected to Phi Beta Kappa, in 1880. He then studied briefly at Columbia Law School but soon turned to writing and politics as a career. In 1880 he married Alice Hathaway Lee, by whom he had one daughter, Alice. After his first wife’s death, in 1886 he married Edith Kermit Carow (Edith Roosevelt), with whom he lived for the rest of his life at Sagamore Hill, an estate near Oyster Bay, Long Island, New York. They had five children: Theodore, Jr., Kermit, Ethel, Archibald, and Quentin.

As a child, Roosevelt had suffered from severe asthma, and weak eyesight plagued him throughout his life. By dint of a program of physical exertion, he developed a strong physique and a lifelong love of vigorous activity. He adopted “the strenuous life,” as he entitled his 1901 book, as his ideal, both as an outdoorsman and as a politician.

Elected as a Republican to the New York State Assembly at 23, Roosevelt quickly made a name for himself as a foe of corrupt machine politics. In 1884, overcome by grief by the deaths of both his mother and his wife on the same day, he left politics to spend two years on his cattle ranch in the badlands of the Dakota Territory, where he became increasingly concerned about environmental damage to the West and its wildlife. Nonetheless, he did participate as a delegate to the Republican National Convention in 1884. His attempt to reenter public life in 1886 was unsuccessful; he was defeated in a bid to become mayor of New York City. Roosevelt remained active in politics and again battled corruption as a member of the U.S. Civil Service Commission (1889–95) and as president of the New York City Board of Police Commissioners. Appointed assistant secretary of the navy by President William McKinley, he vociferously championed a bigger navy and agitated for war with Spain. When war was declared in 1898, he organized the 1st Volunteer Cavalry, known as the Rough Riders, who were sent to fight in Cuba. Roosevelt was a brave and well-publicized military leader. The charge of the Rough Riders (on foot) up Kettle Hill during the Battle of Santiago made him the biggest national hero to come out of the Spanish-American War.

On his return, the Republican bosses in New York tapped Roosevelt to run for governor, despite their doubts about his political loyalty. Elected in 1898, he became an energetic reformer, removing corrupt officials and enacting legislation to regulate corporations and the civil service. His actions irked the party’s bosses so much that they conspired to get rid of him by drafting him for the Republican vice presidential nomination in 1900, assuming that his would be a largely ceremonial role.

Elected with McKinley, Roosevelt chafed at his powerless office until September 14, 1901, when McKinley died after being shot by an assassin and he became president. Six weeks short of his 43rd birthday, Roosevelt was the youngest person ever to enter the presidency. Although he promised continuity with McKinley’s policies, he transformed the public image of the office at once. He renamed the executive mansion the White House and threw open its doors to entertain cowboys, prizefighters, explorers, writers, and artists. His refusal to shoot a bear cub on a 1902 hunting trip inspired a toy maker to name a stuffed bear after him, and the teddy bear fad soon swept the nation. His young children romped on the White House lawn, and the marriage of his daughter Alice in 1905 to Representative Nicholas Longworth of Ohio became the biggest social event of the decade.

From what he called the presidency’s “bully pulpit,” Roosevelt gave speeches aimed at raising public consciousness about the nation’s role in world politics, the need to control the trusts that dominated the economy, the regulation of railroads, and the impact of political corruption. He appointed young, college-educated men to administrative positions. But active as he was, he was cautious in his approach to domestic affairs. Roosevelt recognized that he had become president by accident, and he wanted above all to be elected in 1904. Likewise, as sensitive as he was to popular discontent about big business and political machines, he knew that conservative Republicans who were bitterly opposed to all reforms controlled both houses of Congress. Roosevelt focused his activities on foreign affairs and used his executive power to address problems of business and labor and the conservation of natural resources.

Above all, Roosevelt relished the power of the office and viewed the presidency as an outlet for his unbounded energy. He was a proud and fervent nationalist who willingly bucked the passive Jeffersonian tradition of fearing the rise of a strong chief executive and a powerful central government. “I believe in a strong executive; I believe in power,” he wrote to British historian Sir George Otto Trevelyan. “While President, I have been President, emphatically; I have used every ounce of power there was in the office.…I do not believe that any President ever had as thoroughly good a time as I have had, or has ever enjoyed himself as much.”
