Trained by John Madden, in 1907 King James faced stiff competition from future Hall of Fame inductee Colin.
However, King James won the important Tremont Stakes and at age three was a top contender in New York racing.
Of his twelve starts that year, he had ten wins and two seconds, which earned him a historical Championship as the Top Handicap Male Horse in the United States.
He was sent to stud duty at Henry T. Oxnard's Blue Ridge Farm in Virginia, where he sired ten stakes race winners.
King James was the damsire of Dark Secret and full sisters Mona Bell, the 2000 Canadian Horse Racing Hall of Fame inductee, and Iribelle, a foundation mare for E. P. Taylor's National Stud of Canada farm.
