The Val di Crati was an administrative region in the Kingdom of Sicily. It was the territory originally conquered by Robert Guiscard in the 1050s. At that time, its population was a mix of Greek and Lombard (Latin) Christians. Under the Hohenstaufen and Angevin kings, the Val di Crati became closely associated with the terra iordanis, the land of Jordan (died 1092), son of Roger I. The terra iordanis retained its distinct identity into the 13th century.
