Andorra and France have an unusual and long relationship. Andorra was created by Charlemagne as a buffer state between France and the Umayyad conquest of Hispania. In 1278, under terms of "pareage" agreement, Andorra adopted joint allegiance to a French and a Spanish prince after disputes between French heirs to the Urgel countship and the Spanish bishops of Urgell. For more than 700 years Andorra was ruled jointly by the leader of France and the Spanish Bishop of Urgell. In 1607, a French royal edict establishes the French head-of-state and bishop of Urgell as co-princes. In 1936, during the Spanish Civil War, France sent troops to protect Andorra from the spillover of the civil war.
