Bloodlines
While Shagyas are not considered "pure" or asil Arabians, they have a closed stud book and have special status within the World Arabian Horse Association (WAHO). In 1978, WAHO stated that Shagya Arabians that have been bred pure after the system of Babolna and Topolcianky may be termed "pure bred Shagya Arabians", and the Shagya breeders' organisation is under WAHO patronage as associate members, allowed to use the WAHO emblem. However, WAHO also was clear that Purebred" in this case means that the horses have been bred pure among themselves and are not to be confused with the term "purebred Arabian." Some aficionados note that the meticulous recordkeeping of the Hungarian studs actually has produced horses with longer and more complete pedigrees than some horses accepted as "purebred" Arabians by mainstream registries. However, in spite of this argument, Shagyas remain a distinct bloodline group and are generally not accepted as "pure-blooded Arabians."
