Andorra–Spain relations
Diplomatic relations between the Principality of Andorra and the Kingdom of Spain
Andorra and Spain are members of the Council of Europe, Organization of Ibero-American States and the United Nations.
History
Andorra and Spain have an unusual and long relationship. Andorra was created by Charlemagne as a buffer state between the Carolingian Empire and al-Andalus. 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 bishop of Urgell. During the Spanish Civil War, Andorra received refugees from both sides of the Spanish conflict. During World War II, Andorra became an important smuggling route from Vichy France into Francoist Spain.
Official diplomatic relations between Andorra and Spain were established after the signing of a joint Treaty of Good Neighborhood, Friendship and Cooperation between Andorra, France and Spain; after Andorra adopted a new constitution establishing them as a parliamentary democracy. The bishop of Urgell acts as a co-prince of Andorra along with the president of France. In 1993, Spain opened a resident embassy in Andorra la Vella.
This brief starts where responsible research should: with the source description of “Andorra–Spain relations” as diplomatic relations between the Principality of Andorra and the Kingdom of Spain. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as diplomatic relations between the Principality of Andorra and the Kingdom of Spain. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jul 31, 2026. The linked authority identifier is Q21402506. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1278 and 1993.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
