In the winter of 1975, just before the death of its long-time dictator Generalissimo Francisco Franco, Spain was confronted with an intensive campaign of territorial demands from Morocco and, to a lesser extent, from Mauritania. These culminated in the "Marcha Verde" ('Green March'). After negotiating the Madrid Accords with Morocco and Mauritania, Spain withdrew its forces and settlers from the territory.
