Tribes of Arabia in the context of "History of Islam"

Arabia Petraea (lit. 'Rocky Arabia') was a Roman province from the 2nd century to the 7th century. It was established after the Roman Empire conquered the Nabataean Kingdom in 106 and existed until the Muslim conquest of the Levant in the 630s. Spanning much of the Sinai Peninsula and part of the Levant, it was bordered by Syria to the north, by Judaea (later Syria Palaestina) to the west, and by Egypt to the southwest. To the east and southeast of Arabia Petraea was non-Roman territory that the Romans knew as Arabia Deserta. These two regions, together with a third region in South Arabia that was called Arabia Felix, accounted for the Arabian Peninsula in Roman geography.

Annexed by Trajan (r. 98–117), Arabia Petraea was a key province along the Limes Arabicus, which delineated the Roman Empire's borders throughout the Arabian Desert. It was also the only province in the Near East that the Romans did not gain and subsequently lose during Trajan's reign, unlike Armenia, Assyria, and Mesopotamia. The province's capital city was initially Petra, as it had been under the Nabataeans, but Bosra later served in this capacity. Most of the province's land was a vast desert that was sparsely populated by nomadic Arab tribes, though there were several urban settlements closer to the Jordan River.

Al-Marwani (Arabic: ُٱلْمَرْوَنِي, romanized: al-Marwānī) or Banu Marwan (Arabic: بَنِوُ مَرْوَانَ, lit. 'Sons of Marwan'), also referred to as the Marwanids (Arabic: ٱلْمَرْوَنِيُون, romanized: al-Marwāniyūn), is a prominent Arab clan belonging to the Banu Umayya branch of the Quraysh tribe. They are the descendants of Marwan ibn al-Hakam, fourth Umayyad caliph and paternal first cousin of the Rashidun caliph Uthman ibn Affan. Their roots lie in the holy city of Mecca in the Hejaz, the ancestral homeland of the Quraysh tribe, while their historical establishment was in Damascus, Syria. They are considered first cousins of the Banu Hashim, the clan of the Prophet Muhammad, since Umayya ibn Abd Shams ibn Abd Manaf was the paternal nephew of Hashim ibn Abd Manaf. They are also cousins of the Banu Shayba clan of Quraysh, the hereditary custodians of the Kaaba, through Marwan's maternal grandmother al-Sa'ba bint Abi Talha Abd Allah ibn Abd al-Uzza al-Abdariyya, the paternal aunt of Uthman ibn Talha ibn Abd Allah al-Abdari upon whom the Prophet Muhammad entrusted the guardianship of the keys of the Kaaba after the Conquest of Mecca.

The clan arrived in Damascus in the second half of the 7th century CE when Marwan I, the family's progenitor, moved from the Hejaz to Syria. His accession at the tribal conclave of Marj Rahit (684) marked the transfer of the caliphate within the Banu Umayya clan from the family of Abu Sufyan to his family. The family constitutes one of the two principal cadet branches of the Umayyad dynasty, the other being the Sufyanids, descended from Muʿawiya I ibn Abi Sufyan. At their height, the Marwanis represented the dominant branch of the Umayyad family, producing most of its ruling members and remaining the most numerous line of Umayyad descendants in later generations. The family supplied caliphs, princes, governors and commanders in the 7th–11th centuries and continued as a recognizable lineage in the central Islamic lands and in al-Andalus after 750.

ʿĀd (Arabic: عاد, ʿĀd) was an ancient tribe in pre-Islamic Arabia. 'Ad is best known for being mentioned two dozen times in the Quran, often in conjunction with Thamud. Recently, it has been shown that 'Ad was a tribe that existed two millennia ago in the Wadi Rum region of the southern Jordan.

The tribe's members, referred to as ʿĀdites, formed a prosperous nation until they were destroyed in a violent storm. According to Islamic tradition, the storm came after they had rejected the teachings of a monotheistic prophet named Hud. 'Ad is regarded as one of the original tribes of Arabia, "The Extinct Arabs".

The Qedarites (Ancient North Arabian: 𐪄𐪕𐪇, romanized: qdr) were an ancient Arab tribal confederation centred in their capital Dumat al-Jandal in the present-day Saudi Arabian province of Al-Jawf. Attested from the 9th century BC, the Qedarites formed a powerful polity which expanded its territory throughout the 9th to 7th centuries BC to cover a large area in northern Arabia stretching from Transjordan in the west to the western borders of Babylonia in the east, before later consolidating into a kingdom that stretched from the eastern limits of the Nile Delta in the west till Transjordan in the east and covered much of southern Judea (then known as Idumea), the Negev and the Sinai Peninsula.

The Qedarites played an important role in the history of the Levant and North Arabia, where they enjoyed close relations with the nearby Canaanite and Aramaean states and became important participants in the trade of spices and aromatics imported into the Fertile Crescent and the Mediterranean world from South Arabia. Having engaged in both friendly ties and hostilities with the Mesopotamian powers such as the Neo-Assyrian and Neo-Babylonian empires, the Qedarites eventually became integrated within the structure of the Achaemenid Empire. Closely associated with the Nabataeans, who may have eventually assimilated the Qedarites at the end of the Hellenistic period.

Arabization or Arabicization (Arabic: تعريب, romanized: taʻrīb) is a sociological process of cultural change in which a non-Arab society becomes Arab, meaning it either directly adopts, is forced to accept, or becomes strongly influenced by the Arabic language, culture, literature, art, music, and ethnic identity as well as other socio-cultural factors. It is a specific form of cultural assimilation that often includes a language shift or linguistic imperialism. The term applies not only to cultures, but also to individuals, as they acclimate to Arab culture and become "Arabized". Arabization took place after the Muslim conquest of the Middle East and North Africa, as well as during the more recent Arab nationalist policies toward non-Arabic speaking minorities in modern Arab states, such as Algeria, Iraq, Syria, Egypt, Bahrain, and Sudan.

After the rise of Islam in the Hejaz and subsequent Muslims conquests, Arab culture and language spread outside the Arabian Peninsula through trade and intermarriages between members of the non-Arab local population and the peninsular Arabs. The Arabic language began to serve as a lingua franca in these areas and various dialects were formed. This process was accelerated by the migration of various Arab tribes outside of Arabia, such as the Arab migrations to the Maghreb and the Levant.

The Quraysh (Arabic: قُرَيْشٍ) are an Arab tribe who controlled Mecca before the rise of Islam. Their members were divided into ten main clans, most notably including the Banu Hashim, into which Islam's founder prophet Muhammad was born. By the seventh century, they had become wealthy merchants, dominating trade between the Indian Ocean, East Africa, and the Mediterranean. The tribe ran caravans to Gaza and Damascus in summer and to Yemen in winter, while also mining and pursuing other enterprises on these routes.

When Muhammad began preaching Islam in Mecca, the Quraysh initially showed little concern. However, their opposition to his activities quickly grew as he increasingly challenged Arab polytheism, which was prevalent throughout pre-Islamic Arabia. As relations deteriorated, Muhammad and his followers migrated to Medina (the journey known as the Hijrah) after negotiating with the Banu Aws and the Banu Khazraj to mediate their conflict. However, the two sides proved unable to reach a peaceful resolution, and the Quraysh continued to obstruct Muhammad's community's attempts to perform the Islamic pilgrimage at Mecca, prompting him to confront them through armed conflict, primarily by conducting raids on their caravans. These raids eventually escalated into several major battles, including those at Badr, Uhud, and "the Trench" (Medina's outskirts). Following these engagements and changes in Medina's political landscape, including the expulsion of three Jewish tribes, Muhammad reportedly shifted the focus of his military campaigns from Quraysh caravans to the northern Arab tribes, such as the Banu Lahyan and the Banu Mustaliq.
