The Four Horsemen were a professional wrestling stable in the National Wrestling Alliance and later World Championship Wrestling that was disbanded in 1999. The original group featured Ric Flair, Arn and Ole Anderson, and Tully Blanchard. Ric Flair and Arn Anderson have been constant members in each incarnation of the group except once following Arn Anderson's neck injury where Curt Hennig was given Arn's "spot" in the Horsemen.
In August 1997, Arn Anderson retired due to a neck/back injury that did not allow him to wrestle. Curt Hennig took his spot as "The Enforcer". In September, Hennig turned on the Horsemen and joined the nWo. Flair disbanded the group and they went their separate ways.
