Banu Hilal in the context of Hammadids

Tunisia, officially the Republic of Tunisia, is a country in the Maghreb region of North Africa. It is bordered by Algeria to the west and southwest, Libya to the southeast, and the Mediterranean Sea to the north and east. Tunisia also shares maritime borders with Italy through the islands of Sicily and Sardinia to the north and Malta to the east. It features the archaeological sites of Carthage dating back to the 9th century BC, as well as the Great Mosque of Kairouan. Known for its ancient architecture, souks, and blue coasts, it covers 163,610 km (63,170 sq mi), and has a population of 12.1 million. It contains the eastern end of the Atlas Mountains and the northern reaches of the Sahara desert; much of its remaining territory is arable land. Its 1,300 km (810 mi) of coastline includes the African conjunction of the western and eastern parts of the Mediterranean Basin. Tunisia is home to Africa's northernmost point, Cape Angela. Located on the northeastern coast, Tunis is the capital and largest city of the country, which is itself named after Tunis. The official language of Tunisia is Arabic. The vast majority of Tunisia's population is Arab and Muslim. Vernacular Tunisian Arabic is the most spoken language, and French serves as an administrative and educational language in some contexts, but has no official status.

Beginning in early antiquity, Tunisia was inhabited by the indigenous Berbers. The Phoenicians, a Semitic people, began to arrive in the 12th century BC, settling on the coast and establishing several settlements, of which Carthage emerged as the most powerful by the 7th century BC. The descendants of the Phoenician settlers came to be known as the Punic people. Ancient Carthage was a major mercantile empire and a military rival to the Roman Republic until 146 BC when it was defeated by the Romans who occupied Tunisia for most of the next 800 years. The Romans introduced Christianity and left architectural legacies like the Amphitheatre of El Jem. In the 7th century AD, Arab Muslims conquered Tunisia and settled with their tribes and families, bringing Islam and Arab culture. A later large-scale Arab migration of Banu Hilal and Banu Sulaym tribes in the 11th-12th centuries accelerated this process. By around the 15th century, the region of modern-day Tunisia had already been almost completely Arabized. Then, in 1546, the Ottoman Empire established control, holding sway until 1881, when the French conquered Tunisia. In 1956, Tunisia gained independence as the Tunisian Republic. Today, Tunisia's culture and identity are rooted in this centuries-long intersection of different cultures and ethnicities.

The Arab migrations to the Maghreb involved successive waves of migration and settlement by Arab people in the Maghreb region of Africa, encompassing modern-day Algeria, Libya, Morocco and Tunisia. The process took place over several centuries, lasting from the early 7th century to the 17th century. The Arab migrants hailed from the Middle East, particularly the Arabian Peninsula, with later groups arriving from the Levant and Iraq.

The influx of Arabs to the Maghreb began in the 7th century with the Arab conquest of the Maghreb, when Arab armies conquered the region as part of the early Muslim conquests. This initial wave of Arab migration was followed by subsequent periods of migration and settlement, notably during the Umayyad and Abbasid caliphates and later Arab dynasties. However, the most significant wave of Arab migration occurred in the 11th century with the arrival of more Bedouin tribes from the Arabian Peninsula, such as Banu Hilal, Banu Sulaym, and Maqil. The last significant wave of Arab migration to the Maghreb was from Al-Andalus in the 17th century as a result of the Reconquista. These migrants established numerous Arab empires and dynasties in the Maghreb, such as the Aghlabids, Idrisids, Sulaymanids, Salihids, Fatimids, Saadians and 'Alawites.

El-Mansuriya or Mansuriya (Arabic: المنصورية), also known as Sabra or Sabra al-Mansuriyya, near Kairouan, Tunisia, was the capital of the Fatimid Caliphate during the rule of the Ismaili Imams al-Mansur bi-Nasr Allah (r. 946–953) and al-Mu'izz li-Din Allah (r. 953–975).

Built between 946 and 972, el-Mansuriya was a walled city holding elaborate palaces surrounded by gardens, artificial pools and water channels. It was briefly the centre of a powerful state that encompassed most of North Africa and Sicily. It continued to serve as provincial capital of the Zirids until 1057, when it was destroyed by the invading Banu Hilal tribes. Any useful objects or relics were scavenged during the centuries that followed. Today, only faint traces remain.

Beni Ḥassan (Arabic: بني حسان "sons of Ḥassān") is a Bedouin Arab tribe which inhabits Western Sahara, Mauritania, Morocco and Algeria. It is one of the four sub-tribes of the Banu Maqil who emigrated in the 11th century from South Arabia to the Maghreb with the Banu Hilal and Banu Sulaym Arab tribes. In the 13th century, they took the Sanhaja territories in the southwest of the Sahara. In Morocco, they first settled, alongside their Maqil relatives, in the area between Tadla and the Moulouya River. The Sous Almohad governor called upon them for help against a rebellion in the Sous, and they resettled in and around that region. They later moved to what is today Mauritania, and from the 16th century onwards, they managed to push back all black peoples southwards to the Senegal Valley river. The Beni Hassan and other warrior Arab tribes dominated the Sanhaja Berber tribes of the area after the Char Bouba war of the 17th century. As a result, Arabs became the dominant ethnic group in Western Sahara and Mauretania. The Bani Hassan dialect of Arabic became used in the region and is still spoken, in the form of Hassaniya Arabic. The hierarchy established by the Beni Hassan tribe gave Mauritania much of its sociological character. That ideology has led to oppression, discrimination and even enslavement of other groups in Mauritania.

The Banu Sulaym (Arabic: بنو سليم) is an Arab tribe that dominated part of the Hejaz in the pre-Islamic era. They maintained close ties with the Quraysh of Mecca and the inhabitants of Medina, and fought in a number of battles against the Islamic prophet Muhammad before ultimately converting to Islam before his death in 632. They took part in the Muslim conquest of Syria, and established themselves in the Jazira (Upper Mesopotamia), while part of the tribe remained in the Hejaz. During the early Muslim period, the tribe produced notable generals such as Safwan ibn Mu'attal, Abu'l-A'war and Umayr ibn al-Hubab. Those who remained in Arabia were largely absorbed by the Banu Harb of Yemen beginning in the 9th century, while those in Syria and the Jazira were expelled to Upper Egypt by the Fatimid Caliphs in the late 10th century for supporting the Qarmatians. In the mid-11th century, a prolonged famine in Egypt prompted the tribe to migrate westward with the Banu Hilal into Libya. There, the Sulaym and its sub-tribes established themselves mainly in Cyrenaica, where to the present day, many of the Arab tribes of that region trace their descent to the Sulaym.

The Banu Ma'qil (Arabic: بنو معقل, romanized: Banū Maʿqil) is an Arab nomadic tribe that originated in South Arabia. The tribe emigrated to the Maghreb region of North Africa with the Banu Hilal and Banu Sulaym tribes in the 11th century. They mainly settled in and around the Saharan wolds and oases of Morocco; in Tafilalt, Wad Nun (near Guelmim), Draa and Taourirt. With the Ma'qil being a Bedouin tribe that originated in the Arabian Peninsula, like Banu Hilal and Banu Sulaym, they adapted perfectly to the climatic desert conditions of the Maghreb, discovering the same way of life as in the Arabian Peninsula. The Ma'qil branch of Beni Hassan which came to dominate all of Mauritania, Western Sahara, south Morocco, and south-west Algeria, spread the Hassaniya Arabic dialect, which is very close to classical Arabic.

Arabized Berbers are Berbers whose language is a local dialect of Arabic and whose culture is Arab culture, as a result of Arabization.

The widespread language shift from Berber to Arabic happened, at least partially, due to the privileged status that the Arabic language has generally been given in the states of North Africa, from the Arab conquest in 652 up until the French colonialism in the twentieth century, as well as the migration of the Banu Hilal and Banu Sulaym tribes from Arabia to North Africa. The centuries-long Arab migration to the Maghreb from the 7th to the 17th century played a significant role in Arabizing the native Berber population in addition to changing the population's demographic breakdown.
