While Maximum Security was the first horse ever to be disqualified from a victory in the Kentucky Derby as the result of a stewards' ruling regarding an infraction during the running of the race, he has a parallel in European racing. Unbeaten at the time that he ran in his European Classic, this champion likewise crossed the line first but was disqualified for a foul committed during the race in a controversial decision, making him the first horse to be disqualified in the history of his Classic. He never raced again but became a champion sire nonetheless. Who was he?
