Foaled on 30 April 1946, Star Kingdom was bred by Richard Ball, master of Cloghran Stud, in County Dublin, Ireland.

He was beaten by Abernant by the shortest of short heads in the National Breeders' Produce Stakes at Sandown Park and his jockey `Sam Wragg thought he had won.

Timeform's assessment of him was that he possessed a fine turn of speed and was at his best when opponents did not take him off his feet too early in the race.

[6] Star Kingdom was purchased by Alf Ellison, Reg Moses and Stanley Wootton[7] at a cost of £4,000 and sent to Australia in 1951.

Upon arrival it was obvious that he had not travelled well, and he stood only 15 hands and 1⁄2 inch high, leaving his purchasers with serious doubts about the wisdom of their choice.

Standing at Barramul Stud for 16 successive seasons (1951–1966), he died from a bowel blockage, at the age of 21, on 21 April 1967.
