Morocco (officially known as the Kingdom of Morocco, is a unitary sovereign state located in the Maghreb region of North Africa. It is one of the native homelands of the indigenous Berber people. Geographically, Morocco is characterised by a rugged mountainous interior, large tracts of desert and a lengthy coastline along the Atlantic Ocean and Mediterranean Sea. Morocco has a population of over 33.8 million and an area of. Its capital is Rabat, and the largest city is Casablanca. Other major cities include Marrakesh, Tangier, Salé, Fes, Meknes and Oujda. A historically prominent regional power, Morocco has a history of independence not shared by its neighbours. Since the foundation of the first Moroccan state by Idris I in 788 AD, the country has been ruled by a series of independent dynasties, reaching its zenith under the Almoravid dynasty and Almohad dynasty, spanning parts of Iberia and northwestern Africa. The Marinid and Saadi dynasties continued the struggle against foreign domination, and Morocco remained the only North African country to avoid Ottoman occupation. The Alaouite dynasty, the current ruling dynasty, seized power in 1631. In 1912, Morocco was divided into French and Spanish protectorates, with an international zone in Tangier, and regained its independence in 1956. Moroccan culture is a blend of Berber, Arab, West African and European influences. Morocco claims the non-self-governing territory of Western Sahara, formerly Spanish Sahara, as its Southern Provinces. After Spain agreed to decolonise the territory to Morocco and Mauritania in 1975, a guerrilla war arose with local forces. Mauritania relinquished its claim in 1979, and the war lasted until a cease-fire in 1991. Morocco currently occupies two thirds of the territory, and peace processes have thus far failed to break the political deadlock. Morocco is a constitutional monarchy with an elected parliament. The King of Morocco holds vast executive and legislative powers, especially over the military, foreign policy and religious affairs. Executive power is exercised by the government, while legislative power is vested in both the government and the two chambers of parliament, the Assembly of Representatives and the Assembly of Councillors. The king can issue decrees called dahirs, which have the force of law. He can also dissolve the parliament after consulting the Prime Minister and the president of the constitutional court. Morocco's predominant religion is Islam, and the official languages are Arabic and Berber, with Berber being the native language of Morocco before the Arab conquest in the 600s AD. The Moroccan dialect of Arabic, referred to as Darija, and French are also widely spoken. Morocco is a member of the Arab League, the Union for the Mediterranean and the African Union. It has the fifth largest economy of Africa.

Tunisia (تونس; Berber: Tunes, ⵜⵓⵏⴻⵙ; Tunisie), officially the Republic of Tunisia, (الجمهورية التونسية) is a sovereign state in Northwest Africa, covering. Its northernmost point, Cape Angela, is the northernmost point on the African continent. It is bordered by Algeria to the west and southwest, Libya to the southeast, and the Mediterranean Sea to the north and east. Tunisia's population was estimated to be just under 11.93 million in 2016. Tunisia's name is derived from its capital city, Tunis, which is located on its northeast coast. Geographically, Tunisia contains the eastern end of the Atlas Mountains, and the northern reaches of the Sahara desert. Much of the rest of the country's land is fertile soil. Its of coastline include the African conjunction of the western and eastern parts of the Mediterranean Basin and, by means of the Sicilian Strait and Sardinian Channel, feature the African mainland's second and third nearest points to Europe after Gibraltar. Tunisia is a unitary semi-presidential representative democratic republic. It is considered to be the only full democracy in the Arab World. It has a high human development index. It has an association agreement with the European Union; is a member of La Francophonie, the Union for the Mediterranean, the Arab Maghreb Union, the Arab League, the OIC, the Greater Arab Free Trade Area, the Community of Sahel-Saharan States, the African Union, the Non-Aligned Movement, the Group of 77; and has obtained the status of major non-NATO ally of the United States. In addition, Tunisia is also a member state of the United Nations and a state party to the Rome Statute of the International Criminal Court. Close relations with Europe in particular with France and with Italy have been forged through economic cooperation, privatisation and industrial modernization. In ancient times, Tunisia was primarily inhabited by Berbers. Phoenician immigration began in the 12th century BC; these immigrants founded Carthage. A major mercantile power and a military rival of the Roman Republic, Carthage was defeated by the Romans in 146 BC. The Romans, who would occupy Tunisia for most of the next eight hundred years, introduced Christianity and left architectural legacies like the El Djem amphitheater. After several attempts starting in 647, the Muslims conquered the whole of Tunisia by 697, followed by the Ottoman Empire between 1534 and 1574. The Ottomans held sway for over three hundred years. The French colonization of Tunisia occurred in 1881. Tunisia gained independence with Habib Bourguiba and declared the Tunisian Republic in 1957. In 2011, the Tunisian Revolution resulted in the overthrow of President Zine El Abidine Ben Ali, followed by parliamentary elections. The country voted for parliament again on 26 October 2014, and for President on 23 November 2014.
