Kingdom of Dertosa (Acta Est Fabula)

The Frankish Kingdom of Dertosa (Latin: Francorum Regnum Dertosam), or simply known as Kingdom of Dertosa or Dertosa, was a kingdom established in Hispania between 426 and 528. It was created after the Western Roman Emperor Flavius II, who promised lands to his Frankish mercenaries, was forced to give Roman territories to Engilbert and his men.

During its exisence, it served as a buffer zone between the Western Roman Empire and the Alan Kingdom. The kingdom quickly fragmented following the death of Engilbert and the beginning of the Dertosan Civil War which ended by its annexation by the Alan Kingdom in 458.
