Master of the Horse (Sweden)
Master of the Horse (Swedish: Överhovstallmästare) was a court clerk, who held one of the foremost rankings of the Royal Court of Sweden (next to the Överstekammarherren and just before the Överhovjägmästaren). He had the highest oversight of the Royal Stables, but this was governed by the First Crown Equerry, and he was for a time head of the state stud farm service in Sweden, thereby succeeding the former Riksstallmästaren in some of his duties.
