The Skowronek controversy
Lady Wentworth was satisfied that Skowronek was a purebred (or asil) Arabian, tracing his pedigree and strain to several reliable desert sources. In the General Stud Book, however, Skowronek's pedigree ends with three grandparents. This has led some Arabian enthusiasts to question if Skowronek was in fact a purebred. His sire, Ibrahim, was desert-bred and imported to Poland. His dam Jaskoulka (variously known as Yascolka or Yaskolka) was a Polish-bred Arabian. However, while the Poles had bred Arabians for centuries and kept careful pedigree records, they also crossed Arabian stallions on Thoroughbred and other non-Arabian mares. In addition, some breeders used different terminology to distinguish horses bred in the desert and imported to Poland from the descendants of those horses bred in Poland, with translation issues leading some English language researchers to argue that second and third generation Polish-bred purebred Arabians were not actually purebred. For these reasons, some people argued that his dam was not asil.
Research of Jaskoulka's pedigree shows that her sire Rymnik and her dam Epopeja (also spelled Epopeia or Epopya) both traced to Abbas Pasha horses. Nonetheless, due to this controversy, some private breeders' organizations, such as Al Khamsa, exclude descendants of Skowronek.
