Of all our great presidents, Theodore Roosevelt is the only one whose greatness increased out of office. When he toured Europe in 1910 as plain “Colonel Roosevelt”, he was hailed as the most famous man in the world. Crowned heads vied to put him up in their palaces. “If I see another king,” he joked, “I think I shall bite him.” 

Had TR won his historic “Bull Moose” campaign in 1912 (when he outpolled the sitting president, William Howard Taft), he might have averted World War I, so great was his international influence. Had he not died in 1919, at the early age of 60, he would unquestionably have been reelected to a third term in the White House and completed the work he began in 1901 of establishing the United States as a model democracy, militarily strong and socially just. 

This biography by Edmund Morris, the Pulitzer Prize and National Book Award-winning author of The Rise of Theodore Roosevelt and Theodore Rex, is itself the completion of a trilogy sure to stand as definitive. Packed with more adventure, variety, drama, humor, and tragedy than a big novel, yet documented down to the smallest fact, it recounts the last decade of perhaps the most amazing life in American history. What other president has written 40 books, hunted lions, founded a third political party, survived an assassin’s bullet, and explored an unknown river longer than the Rhine?
