Original: Popular types of Arabians are labeled "Polish," "Spanish," "Crabbet," "Russian," "Egyptian", and "Domestic" (describing horses whose ancestors were imported to the United States prior to 1944, including those from programs such as Kellogg, Davenport, Maynesboro, Babson, Dickenson and Selby).
Simplified: Arabian horse families are now labeled by where their most recent ancestors were bred, such as "Polish," "Spanish," "Crabbet" (from England), "Russian," "Egyptian", and "Domestic" (in the United States).
