Spanish irredentism claims for a unify Iberian Peninsula. The recovey of Gibraltar, a standing territorial vindication in the Spanish foreign policy, and an aproximation with Portugal for the reunification, are the main proposals.
A Spain holding all of the Iberian Peninsula became a topic in Spanish nationalism beginning in the 19th century, with proponents idealizing historical Roman Hispania when all of the Iberian Peninsula was united under the same rule. The concept of Spain as a cultural and political unit had been developed centuries earlier with the publishing of Father Mariana's History of Spain (1598) in which Mariana supported a Hispanic identity.
There has been strong Spanish objection to the separation of Gibraltar from Spain, a British colony since the Treaty of Utrecht (1713), in the aftermath of the Spanish War of Succession. During the Spanish Civil War, the Carlists and the Falange prior to the two parties' unification in 1937, both promoted the incorporation of Portugal into Spain, such as the period of the Iberian Union. The Carlists stated that a Carlist Spain would retake Gibraltar and conquer Portugal. The Falange, both prior to and after its merger with the Carlists, supported the unification of Gibraltar and Portugal into Spain, during its early years of existence the Falange produced maps of Spain that included Portugal as a province of Spain. After the Spanish Civil War and the victory of the Nationalist faction led by Francisco Franco, radical members of the Falange called for the incorporation of Portugal and the French Pyrenees into Spain. Franco in a communiqué with Germany on 26 May 1942 declared that Portugal should be annexed into Spain.
The years of World War II were fertile in the projection by several authors of irredentist imaginaries across the Strait of Gibraltar (after all the Strait was to become the "neuralgic point of nationality" to them): according to the africanist Tomás García Figueras "Spain and Morocco are like two halves of the same geographical unity". Historian Jaume Vicens Vives (1940) talked about a "vital space" conceptualised as a "geopolitical basic unit". Rodolfo Gil Benumeya traced the links back to the Neolithic, pointing to a common Ibero-Berber People living at both sides of the Strait. Gil Benumeya and Hernández Pacheco stressed the strengthening of those links due to Morocco being part of "Hispania Tingitana". Some of these authors, transcending historical arguments, even pointed at a Spanish-African union during "the Tertiary" when the Strait would not have existed. As well there were claims about the Spanishness of the Roussillon, the Cerdanya or the Lower Navarre.
