Greater Morocco is a label historically used by some Moroccan anti-colonial political leaders protesting against Spanish, Portuguese, Algerian and French rule, to refer to wider territories historically associated with the Moroccan Sultan. Current usage most frequently occurs in a critical context accusing Morocco, largely in discussing the disputed Western Sahara, of irredentist claims on neighbouring territories. Irredentists[who?], official and unofficial Moroccan claims on territories viewed by Moroccans as having been under some form of Moroccan sovereignty before the colonial era (most frequently with respect to the Spanish enclaves) are rhetorically tied back to an accused expansionism. However, Moroccan government claims make no current reference to the greater Morocco concept, which appears to have died out in the 1970s, except for the case of Western Sahara.
In 1963, following the Independence of Algeria, Morocco attacked a strip of its south-western regions (Tindouf Province and Béchar Province), claiming that parts of them were previously under Moroccan sovereignty. After a month of fighting and some hundreds of casualties, the conflict stalemated (see Sand War).
In the early stages of decolonisation certain elected Moroccan politicians, in particular some members of the Istiqlal party, like Allal al-Fassi, the sole advocate of "total liberation" who refused to enter France even to meet with his Monarch or long-standing nationalist colleagues, were in favor of claiming wider territories historically associated in some way with the Moroccan Sultan. This was initially not supported by the Sultan (later King) of Morocco. Al-Fassi's ambitions gained more support in parliament in the beginning of the sixties, leading to a delay in the recognition of Mauritania (independent in 1960, not recognised by Morocco until 1969).
Al-Fassi's wider claims were effectively abandoned in the later sixties, although Morocco claims Western Sahara and the Spanish plazas de soberanía on its northern coast. Morocco's refusal to accept its post-colonial borders in the case of Western Sahara has put it on a collision course with the African Union, which holds this as one of its principles. As a consequence, Morocco is the only African country to step out of the union, because the Polisario Front, representing the Sahrawi Arab Democratic Republic was awarded a seat. 
After Moroccan independence in 1956 and the death of King Mohammed V, the government of King Hassan II laid claim on several territories, successfully acquiring the Tarfaya Strip, after the Ifni War with Spain, and much of the territory around Ceuta and Melilla, as well as the acquisition of much of Spanish Sahara after Spain handed the territory to Morocco and Mauritania (see the Madrid Accords, it is still currently under dispute with the Polisario front who claim it as the Sahrawi Arab Democratic Republic
Recently in 2002, an armed incident erupted between Morocco and Spain, regarding the uninhabited Perejil Island, located 250m off the Moroccan northern coast. On July 11, 2002 a group of Moroccan soldiers set up base on the islet. The Moroccan government said that they set foot on the island in order to monitor illegal immigration, which was denied by the Spanish government since there had been little co-operation in the matter by that time (a repeated source of complaint from Spain). After protests from the Spanish government, led by José María Aznar, the soldiers were replaced by Moroccan navy cadets who then installed a fixed base on the island. On the morning of July 18, 2002 Spain launched a full-scale military operation to take over the island. The operation was successful and the Moroccan navy cadets were dislodged from the island in a matter of hours without offering any resistance to the Spanish commando attack force. The islet is now deserted.
