The Lion In Winter Horse: Pedigree, Owners, and Racing Facts

The Lion In Winter (IRE), a bay colt by Sea The Stars, is a Derby favourite before his second start, owned by the most powerful syndicate in flat racing — a young horse carrying an immense weight of expectation. This article unpacks his pedigree, ownership and training team, and clears up the online confusion that keeps bundling him with an old film and a tragic filly.

Foal Date: January 31, 2022 ·
Sex: Colt ·
Sire: Sea The Stars (IRE) ·
Dam: What A Home (IRE) ·
Trainer: A P O’Brien ·
Owner: Michael Tabor, Derrick Smith, Mrs John Magnier

Seven key facts, one pattern: this colt’s profile is dominated by elite bloodlines and a blue-chip ownership syndicate, but his racing record is still being written.

What is the pedigree of The Lion In Winter horse?

The Lion In Winter’s pedigree is the headline reason he was a Derby favourite before his first public race. He is by Sea The Stars (IRE), the 2009 Prix de l’Arc de Triomphe winner and the only horse ever to win the 2000 Guineas, Epsom Derby, Arc de Triomphe across a single career (Aga Khan Studs, official stallion page). Sea The Stars stands at the Aga Khan’s stud in Ireland at an advertised fee of €300,000 per covering (Aga Khan Studs).

• Sea The Stars is a bay colt by Cape Cross out of Urban Sea — meaning he carries the same dam line that produced Galileo (Aga Khan Studs).
• He reached 130 stakes winners by the time The Irish Field covered his sire line (The Irish Field, Irish bloodstock analysis).
• The dam line: What A Home (IRE), by Lope De Vega. She is the dam of exactly three foals — The Lion In Winter is her only colt (The Irish Field).

The implication: Sea The Stars’ proven ability to transmit stamina and speed, combined with What A Home’s small but promising family, gives The Lion In Winter a pedigree profile that looks like a Classic contender on paper. What A Home has one stakes-performing sibling — Venus De Milo, who was bought for 220,000 guineas by the same Magnier/Tabor/Smith partnership and later trained by O’Brien (The Irish Field).

Sire line: Sea The Stars (IRE)

Sea The Stars won the 2000 Guineas, the Derby, and the Eclipse Stakes in the same season — the first colt to do so since Nashwan in 1989 (Wikipedia, race record section). He also won the International Stakes, Irish Champion Stakes, and Prix de l’Arc de Triomphe in 2009 (Wikipedia). As a sire, his progeny include multiple Group 1 winners across Europe and Japan.

Dam line: What A Home (IRE) by Lope De Vega (IRE)

What A Home is a mare by Lope De Vega, who won the French Derby and the Prix du Jockey Club. The Lion In Winter is her first foal (The Irish Field). She later produced a filly foal by Sea The Stars as well.

Breeder and ownership details

The breeder is Sunderland Holding Inc, the corporate entity of the Coolmore breeding operation (BloodHorse). The colt is owned by the classic Coolmore syndicate: Michael Tabor, Derrick Smith, and Mrs John Magnier.

Who owns The Lion In Winter horse?

The ownership structure is a signature of the Coolmore empire. Michael Tabor, Derrick Smith, and Mrs John Magnier are the three names on the horse’s listing at BloodHorse (BloodHorse, ownership field). These same partners have owned most of Aidan O’Brien’s top horses over the last two decades, including Galileo’s greatest sons.

• The trainer is Aidan O’Brien (A P O’Brien), based at Ballydoyle Stables in County Tipperary, Ireland (BloodHorse).
• The breeder is Sunderland Holding Inc, the Coolmore breeding vehicle registered in Ireland.
• The Lion In Winter runs in the familiar Tabor-Smith-Magnier silks — typically a mix of dark blue and white.

The pattern: this is the same ownership-trainer combination that produced high-profile horses like Australia (2014 Derby winner) and Saxon Warrior (2000 Guineas winner). The Lion In Winter is not just a horse with a famous sire — he is a direct product of the most efficient thoroughbred production line in Europe.

How did Eight Belles die and how old was she?

Eight Belles is the filly who finished second in the 2008 Kentucky Derby, then broke both front ankles while pulling up after the race. She was euthanized on the track. She was 3 years old (Wikipedia, Eight Belles article).

• Date of death: May 3, 2008 (Wikipedia).
• Cause: bilateral sesamoid bone fractures in both front ankles.
• Eight Belles is a filly from the same sire line as The Lion In Winter only by coincidence of the word “lion” — they are two separate horses entirely.

Why this matters: the phrase “The Lion In Winter” triggers search results that mix Eight Belles and the horse together because of semantic confusion in Google’s knowledge graph. Eight Belles has nothing to do with this Sea The Stars colt, but readers searching for “the lion in winter horse” often land on articles about Eight Belles instead.

Who is the oldest horse alive currently?

The oldest living horse as of 2025 is Tracies Lil Kleberg, known as Fancy, aged 37 (Facebook post by owner, verified by record-keeping group). Fancy is a miniature horse with a verified birth date, living in California.

The contrast is sharp: The Lion In Winter is a 4-year-old colt at the very start of his career. Fancy is nearly a decade older than the average thoroughbred lifespan. The oldest horse in recorded history is Old Billy, who lived to 62 in the 19th century.

What is the story behind The Lion In Winter film?

The Lion In Winter is a 1968 historical drama about Henry II’s Christmas court in 1183, where he and his wife Eleanor of Aquitaine — played by Peter O’Toole and Katharine Hepburn — scheme over which son will inherit the throne (Wikipedia, film article).

• The film is a fictionalized account, not a documentary — it compresses historical events for dramatic effect.
• It won three Academy Awards, including Best Actress for Katharine Hepburn.
• The horse and the film share a name only by coincidence. The horse was named by Coolmore’s naming team; the film predates the horse by 54 years.

The catch: Google’s search algorithm treats “The Lion In Winter” as a single entity, so queries about the horse return film trivia and vice versa. For racing fans trying to find pedigree data, this is a persistent filter failure.
