In early 1975, both Morocco and Mauritania agreed to abide by the decision of the International Court of Justice on the status of the Spanish Sahara, but when the court ruled in October 1975 that neither country was entitled to claim sovereignty over the territory, both governments chose to ignore the decision. In November 1975, they concluded the Madrid Agreements with Spain under which Morocco acquired the northern two-thirds of the territory, while Mauritania acquired the southern third. The agreement also included the proviso that Spain would retain shares in the Bu Craa mining enterprise. Mauritania acquiesced to the agreements under the assumption, probably correct, that Morocco, with its superior military power, would otherwise have absorbed the entire territory.
