Proposed partition of Spain after WW2.
This plan was an actual joint request by Basque and Catalan nationalists should Francoist Spain join the war as an Axis power issued to the British government on January 18th 1941. Both factions considered than an Allied victory was just a matter of time and wanted to take profit from it.
The Basque plan included annexing the next territories: "...on the North the
Pyrenees and the
Bay of Biscay, on the Easte the
Gállego river, on the South the
Ebro river until
Gallur and the water divisory between the Ebro and the
Duero basins from
Moncayo on the whole extension of both vertients and on the West cape
Ajo (Peña Cantábrica)."
The Catalan claims were mostly vague, but they claimed annexing all Catalan-speaking areas into a Greater Catalonia. Spanish-speaking parts of Valencia would also be annexed. Both factions stated that "whatever happened, Spain shall not border France". This means that all lands south of the Pyrenees would be given to either the Basque Republic or Catalonia. Catalan nationalists also claim Aragon and the city of Alger (Alghero, Sardinia), but that falls out of the map.
Andorra would be a joint Franco-Catalan protectorate.
Portugal would annex Galicia should it join the allies (if not, Galicia would be a sovereign nation) but would gain Olivença no matter what.
The Spanish protectorate of Morocco would cede to the French part. The fate of the rest of Spanish colonies is unknow.
The Canaries would become a British protectorate, given that the British war plans if Spain joined the Axis included a quick occupation of the islands before the Germans could use them as U-Boat bases (even if the Canarias would be defended to the last man by the Spaniards). After the war why would be a mandate and in the afterwards they'd become an independent republic.
