Syrian Desert in the context of "Tribes of Arabia"

Arabs (Arabic: عَرَب) are an ethnic group mainly inhabiting the Arab world in West Asia and North Africa. A significant Arab diaspora is present in various parts of the world. Before the spread of Arabic language in the wake of the Arab conquests, "Arab" largely referred to the Semitic inhabitants—both settled and nomadic—of the Arabian Peninsula and the Syrian Desert. In modern usage, it includes people from across the Greater Middle East that share Arabic as a native language.

Arabs have been in the Fertile Crescent for thousands of years. In the 9th century BCE, the Assyrians made written references to Arabs as inhabitants of the Levant, Mesopotamia, and Arabia. Throughout the Ancient Near East, Arabs established influential civilizations starting from 3000 BCE onwards, such as Dilmun, Gerrha, and Magan, playing a vital role in trade between Mesopotamia, and the Mediterranean. Other prominent tribes include Midian, ʿĀd, and Thamud mentioned in the Bible and Quran. Later, in 900 BCE, the Qedarites enjoyed close relations with the nearby Canaanite and Aramaean states, and their territory extended from Lower Egypt to the Southern Levant. From 1200 BCE to 110 BCE, powerful kingdoms emerged such as Saba, Lihyan, Minaean, Qataban, Hadhramaut, Awsan, and Homerite emerged in Arabia. According to the Abrahamic tradition, Arabs are descendants of Abraham through his son Ishmael.

The Tigris (/ˈtaɪɡrɪs/ TY-griss; see below) is the eastern of the two great rivers that define Mesopotamia, the other being the Euphrates. The river flows south from the mountains of the Armenian Highlands through the Syrian and Arabian Deserts, before merging with the Euphrates and reaching to the Persian Gulf.

The Tigris passes through historical cities like Mosul, Tikrit, Samarra, and Baghdad. It is also home to archaeological sites and ancient religious communities, including the Mandaeans, who use it for baptism. In ancient times, the Tigris nurtured the Assyrian Empire, with remnants like the relief of King Tiglath-Pileser.

The era of pre-Islamic Arabia encompasses human history in all parts of the Arabian Peninsula before the rise of Islam. During the prehistoric period, humans first migrate and settle into the peninsula. In the early first millennium BC, writing and recorded history are introduced into the Peninsula, along with the rise of the first kingdoms in the south. In the early seventh century, the pre-Islamic period quickly comes to a close, from the beginning of Muhammad's preachings of Islam, to his establishment of the first Islamic state in 622 in Medina, and the subsequent conquest and political unification of the peninsula shortly after Muhammad's death, in the 630s. Some strands of Islamic tradition interpret the pre-Islamic period as a barbaric, morally un-enlightened period known as the "Jahiliyyah" (Arabic: جَاهِلِيَّة), but historians have not adopted this convention.

Pre-Islamic Arabia's demographics included both nomadic and settled populations, the latter of which eventually developed into distinctive civilizations. Eastern Arabia was home to the region's earliest civilizations, such as Dilmun, which is attested as a prominent trade partner of Mesopotamia during the Bronze Age; and its later pre-Islamic history is marked by the reign of consecutive Iranian empires, including those of the Parthians and the Sasanians. From the early 1st millennium BCE onward, South Arabia became home to a number of kingdoms, such as Sheba and Ma'in; while part of North Arabia became home to the Nabataean Kingdom, which was conquered and annexed by the Roman Empire in 106, thereafter being known as Arabia Petraea and initiating the centuries-long Roman period in Arabia.

Al-Walid ibn Abd al-Malik ibn Marwan (c. 674 – 23 February 715), commonly known as al-Walid I, was the sixth Umayyad caliph, ruling from October 705 until his death in 715. He was the eldest son of his predecessor, Caliph Abd al-Malik (r. 685–705). As a prince, he led annual raids against the Byzantines from 695 to 698 and built or restored fortifications along the Syrian Desert route to Mecca. He became heir apparent in c. 705, after the death of the designated successor, Abd al-Malik's brother Abd al-Aziz ibn Marwan.

Under al-Walid, his father's efforts to centralize government, impose a more Arabic and Islamic character on the state, and expand its borders were continued. He heavily depended on al-Hajjaj ibn Yusuf, his father's powerful viceroy over the eastern half of the caliphate. During his reign, armies commissioned by al-Hajjaj conquered Sind and Transoxiana in the east, while the troops of Musa ibn Nusayr, the governor of Ifriqiya, conquered the Maghreb and Hispania in the west, bringing the caliphate to its largest territorial extent. War spoils from the conquests enabled al-Walid to finance impressive public works, including his greatest architectural achievement, the Great Mosque of Damascus, as well as the al-Aqsa Mosque in Jerusalem, the expansions of the Prophet's Mosque in Medina and the Great Mosque of Sana'a, and the building of the historical city of Anjar. He was the first caliph to institute programs for social welfare, aiding the poor and handicapped among the Muslim Arabs of Syria, who held him in high esteem.

The tribes of Arabia (Arabic: القبائل العربية) have inhabited the Arabian Peninsula for thousands of years and traditionally trace their ancestry to one of two forefathers: Adnan, whose descendants originate from West Arabia, North Arabia, East Arabia, and Central Arabia; or Qahtan, whose descendants originate from South Arabia. Further, it is held in the Abrahamic religions—particularly Islam—that the Arab people are descended from Abraham through his son Ishmael.

From the 7th century onward, concurrent with the spread of Islam, many of these tribes' members began migrating and settling in the various regions that were subdued during the early Muslim conquests, including the Levant, Mesopotamia, Egypt, Khuzestan, the Maghreb, and Sudan. This phenomenon triggered a process of Arabization that significantly influenced demographic shifts across most of West Asia and North Africa, culminating in the growth of the Arab population far beyond the Arabian Peninsula.

The Bedouin, Beduin, or Bedu (/ˈbɛduɪn/ BED-oo-in; Arabic: بَدْو, romanized: badw, singular بَدَوِي badawī) are pastorally nomadic Arab tribes who have historically inhabited the desert regions in the Arabian Peninsula, North Africa, the Levant, and Mesopotamia (Iraq/Kuwait). The Bedouin originated in the Syrian Desert and Arabian Desert but spread across the rest of the Arab world in West Asia and North Africa after the spread of Islam. The English word bedouin comes from the Arabic badawī, which means "desert-dweller", and is traditionally contrasted with ḥāḍir, the term for sedentary people. Bedouin territory stretches from the vast deserts of North Africa to the rocky ones of the Middle East. They are sometimes traditionally divided into tribes, or clans (known in Arabic as ʿašāʾir; عَشَائِر or qabāʾil قبائل), and historically share a common culture of herding camels, sheep and goats. The vast majority of Bedouins adhere to Islam, although there are a small number of Christian Bedouins present in the Fertile Crescent.

Bedouins have been referred to by various names throughout history, including Arabaa by the Assyrians (ar-ba-ea), being a nisba of the noun Arab, a name still used for Bedouins today. They are referred to as the ʾAʿrāb (أعراب) "aɛrāb" in Arabic. While many Bedouins have abandoned their nomadic and tribal traditions for a modern urban lifestyle, others retain traditional Bedouin culture such as the traditional ʿašāʾir clan structure, traditional music, poetry, dances (such as saas), and many other cultural practices and concepts. Some urbanized Bedouins often organise cultural festivals, usually held several times a year, in which they gather with other Bedouins to partake in and learn about various Bedouin traditions—from poetry recitation and traditional sword dances to playing traditional instruments and even classes teaching traditional tent knitting. Traditions like camel riding and camping in the deserts are still popular leisure activities for urban Bedouins who live in close proximity to deserts or other wilderness areas.

The Armenian genocide was the systematic destruction of the Armenian people and identity in the Ottoman Empire during World War I. Spearheaded by the ruling Committee of Union and Progress (CUP), it was implemented primarily through the mass murder of around one million Armenians during death marches to the Syrian Desert and the forced Islamization of others, primarily women and children.

Before World War I, Armenians occupied a somewhat protected, but subordinate, place in Ottoman society. Large-scale massacres of Armenians had occurred in the 1890s and 1909. The Ottoman Empire suffered a series of military defeats and territorial losses, especially during the 1912–1913 Balkan Wars. This sparked fear among CUP leaders that the Armenians, whose homeland in Anatolia they considered the Turkish nation's last refuge, would seek independence. During their invasion of Russian and Persian territory in 1914, Ottoman paramilitaries massacred local Armenians. Ottoman leaders took isolated instances of Armenian resistance as evidence of a widespread rebellion, and decided to permanently forestall the possibility of Armenian autonomy or independence.

The Greek genocide (Greek: Γενοκτονία των Ελλήνων, romanized: Genoktonía ton Ellínon), which included the Pontic genocide, was the systematic killing of the Christian Ottoman Greek population of Anatolia, which was carried out mainly during World War I and its aftermath (1914–1922) – including the Turkish War of Independence (1919–1923) – on the basis of their religion and ethnicity. It was perpetrated by the government of the Ottoman Empire led by the Three Pashas and by the Government of the Grand National Assembly led by Mustafa Kemal Atatürk, against the indigenous Greek population of the Empire. The genocide included massacres, forced deportations involving death marches through the Syrian Desert, expulsions, summary executions, and the destruction of Eastern Orthodox cultural, historical, and religious monuments. Several hundred thousand Ottoman Greeks died during this period. Most of the refugees and survivors fled to Greece (adding over a quarter to the prior population of Greece). Some, especially those in Eastern provinces, took refuge in the neighbouring Russian Empire.

By late 1922, most of the Greeks of Asia Minor had either fled or had been killed. Those remaining were transferred to Greece under the terms of the later 1923 population exchange between Greece and Turkey, which formalized the exodus and barred the return of the refugees. Other ethnic groups were similarly attacked by the Ottoman Empire during this period, including Assyrians and Armenians, and some scholars and organizations have recognized these events as part of the same genocidal policy.
