Andorra and Spain are members of the Council of Europe, Organization of Ibero-American States and the United Nations.
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.[1] 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.[2] 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. In 2005, Andorra was admitted into the Organization of Ibero-American States and that year, Andorran Prime Minister Albert Pintat attended the Ibero-American Summit held in Salamanca, Spain. In January 2015, Spanish Prime Minister Mariano Rajoy became the first Spanish leader to ever visit Andorra. The visit was a clear example of the good state of bilateral relations. The progressive intensification of bilateral relations between Andorra and Spain progressed with the formal invitation, made in November 2016, by Andorran Present Antoni Martí for King Felipe VI of Spain to visit the Principality.
In July 2018, Andorra and Spain highlighted their "strong ties" on the 25th anniversary of the establishment of diplomatic relations.[3] In March 2021, the King and Queen of Spain, Felipe VI and Letizia Ortiz, made the first state visit of a Spanish king to neighboring Andorra, something that had never happened before. The Andorran Head of Government, Xavier Espot Zamora, declared: "it is one more example, but a very significant one, of the excellent bilateral relations".[4] [5]
Spaniards are the largest nationality to visit Andorra for touristic purposes. Spaniards are also the largest foreign residents in Andorra, with over 18,000 Spanish citizens living in Andorra.[6]
