The Tribes of Yemen are those residing within the borders of the Republic of Yemen. While there are no official statistics, some studies suggest that tribes make up about 85% of the population, which was 25,408,288 as of February 2013.CIA World Factbook, Yemen Estimates vary, with approximately 200 tribes in Yemen, although some reports list more than 400.الجزيرة نت Yemen is the most tribal nation in the Arab world, largely due to the significant influence of tribal leaders and their deep integration into various aspects of the state.J. E. Peterson, Tribes and Politics in Yemen p.1

Many tribes in Yemen have long histories, with some tracing their roots back to the era of the Kingdom of Sheba. Throughout history, these tribes have often formed alliances, either to establish or dismantle states. Despite their diverse origins, they frequently share common ancestry. In Yemen, the lineage of the tribe is less important than the alliances it forms.J. E. Peterson, Tribes and Politics in Yemen p.2 Tribes are far from homogeneous societal structures. While several clans may share a common history and "lineage," the tribe in Yemen is not a cohesive political entity. Clans belonging to a common "lineage" may shift their affiliations and loyalties as dictated by needs and circumstances, with the allied tribe also finding a shared "lineage."جواد علي المفصل ج 4 ص 420

Over long periods of time, Yemen remained a unified nation despite the lack of a central government that imposed authority over the entire territory, except for brief periods in Yemen's history. The nation was made up of numerous tribes, and the tribal divisions in Yemen stabilized with the advent of Islam into four federations: Himyar, Madhhaj, Kinda, and Hamdan.حمزة علي لقمان، تاريخ القبائل اليمنية، دار الكلمة، صنعاء، 1985 The Madhhaj tribe group consists of three tribes—Ans, Murad, and Al-Hadda—and they inhabit the eastern regions of Yemen. The Himyar tribes lived in the southern mountainous regions and central plateaus, while the Hamdan federation includes the Hashid and Bakil tribes.محمد محسن الظاهري، القبيلة والتعددية السياسية في اليمن، رسالة دكتوراة The political and economic conditions in Yemen during the Middle Ages and the early modern era led to the redrawing of the tribal map. The Madhhaj tribes joined the Bakil tribal confederation, and some Himyar tribes joined the Hashid confederation.عبد الله عبد الكريم الجرافي، المقتطف من تاريخ اليمن، منشورات العصر الحديث، بيرون، طبعة2، 1987

Origins Classes of Arabs

Most genealogists and historians classify the Arab peoples into two categories: defunct Arabs and those remaining. Defunct Arabs refer to ancient Arab tribes that once lived on the Arabian Peninsula but disappeared before the advent of Islam. No descendants of these tribes remain today due to changes in the natural environment and volcanic eruptions. These tribes include ‘Ād, Thamud, Amliq, Tasm, Jadis, Umim, and Jassim, with Abeel, the first urn, and Dabbar occasionally included.

The remaining Arabs are the descendants of Yarub bin Qahtan and the sons of Ma`ad bin Adnan bin Ad, who adopted the Arabic language from the defunct Arabs. Qahtan and his group became Arabized when they settled in Yemen and mixed with the local people. According to one narration, Qahtan originally spoke Syriac, but his language gradually changed to Arabic as he became Arabized.

There is another classification that divides the Arabs into three categories: defunct Arabs, Arabized Arabs, and Mozarabized Arabs. The latter two categories are collectively known as "remaining Arabs." The Arabs are those descended from Qahtan (or Joktan), as mentioned in the Old Testament. He was the first to speak Arabic, and his descendants are considered the authentic and ancient Arabs. These include the Al-Qahtaniyah from the Himyar, the people of Yemen and its branches, representing the people of southern Arabia, as opposed to the Musta'arabi Jews of the Levant. Additionally, there are the Maadis, who descend from Ma`ad ibn Adnan ibn Ad. They inhabited Najd, Hijaz, and the northern regions and are descended from Ismail ibn Ibrahim. This group became Arabized following the Muslim conquest of the Iberian Peninsula, and they were known as Mozarabs. When Ismail came to Mecca, he spoke Hebrew or Aramaic, but upon assimilating with the Yemenites, he learned their Arabic language.

Ibn Khaldun divides the Arabs into four successive classes over a chronological range: first, the defunct Arabs; second, the Qahtaniyah Arabs; third, the Arabs belonging to them, including those from Adnan, Aws, Khazraj, Ghasasna, and Manathira; and fourth, the Arabs of Al-Mustajimah, who were influenced by the Islamic State.

In fact, the division between the Arabs and the Arabized Arabs originates from what is written in the Old Testament and is derived from accounts of the beginning of creation. Subsequently, genealogists and historians agreed to divide the Arabs, in terms of lineage, into two groups: the Qahtaniyah, whose original homeland was Yemen, and the Adnaniyah, whose original homeland was Hijaz.

History Ancient tribal history

In ancient times, the tribal structure was organized around tribal unions, including the Kingdom of Sheba, Qataban, Ma'in, and Hadhramaut. These four kingdoms gave rise to various tribes. After the advent of Islam, historians knew little about Qataban and Ma'in. As a result, tribes previously affiliated with these kingdoms were often classified under Saba or Himyar, as they were mentioned in the Qur'an or associated with Himyar, the last of the ancient Yemeni kingdoms before Islam.Hommel. Geography and Geschichte of the Alten Orients, I S., 142 – Fritzl Hommel's Geography and History of the Ancient Near East, p. 142Klaus Skipmann's History of the Ancient South Arabian Kingdoms, p. 98 The strongest of these unions was the Sabaean, which established a system similar to federalism, encompassing the four kingdoms and their tribes.

Kingship in Sheba was held by specific tribes or "covens," as indicated by the Sabaean terms "Fishan," "Dhu Khalil," "Dhu Sahar," and "Dhu Ma'ahir." Currently, little is known about these groups, and they are not mentioned in existing writings.David Heinrich Müller, Süd-arabische Studien (1877) p.34 Their rule marked the kingdom's most prosperous period, believed to have lasted from the 12th century BCE to the 4th century BCE.John Philby, Background of Islam p.142

These kings established a "federal" system of governance, granting each tribe or province a degree of autonomy while maintaining military and economic subordination to the kingdom, primarily through tax payments.The Asian Journal, first issue 1874, p. 584 The unique geography of Yemen played a significant role in the emergence of tribes. The mountains and narrow valleys isolated communities from one another, leading to the formation of tribal groups that allied with each other for mutual protection while remaining wary of nearby groups.

Urban Arabs built forts and castles to defend themselves and their resources against both neighboring tribes and external threats. Similarly, the Ahlaf, or tribal alliances, served as protection for Bedouins in the desert. The scarcity of resources in the Arabian Peninsula historically drove people to form isolated tribal groups scattered across the region. Even urban dwellers maintained strong tribal ties and sometimes fabricated lineages to reinforce their alliances, reflecting a deep-seated fear of an uncertain future.

The civilization of the Kingdom of Sheba began to decline after the collapse of the Ma’rib Dam.Ahmed bin Muharib Al-Dhafiri, Happy Yemen in Distant History, Kuwaiti Al-Siyasa newspaper dated 15 July 2010 AD This catastrophic event caused widespread flooding of the surrounding villages, cities, and farms, forcing the population to migrate both internally and externally to nearby and distant regions.The Beginning and the End/Part Two/The Story of Sheba After the event known as Sil al-Aram, the people of Ma'rib dispersed across the land. However, the tribes of Himyar, Madhhaj, and Kinda remained in Yemen, along with Ash'ari and Anmar (Khath'am and Bajila).The Beginning and the End – Part Two – Chapter on the Residence of Six Tribes from Sheba in Yemen.

Yemen then entered a new era characterized by religious conflicts during the period of the Himyarite State. It became a battleground for competing external powers, particularly the Sassanians and the Roman Empire. This rivalry between foreign powers, driven by greed, brought about significant instability in Yemen.Dr. Adnan Tarsis, The Land of Sheba and the First Arab Civilization, Yemen (Arabia Felix), Lebanon, Beirut, Dar Al-Fikr Al-Mu’asim, 2nd edition, 1990, p. 46

The Romans sought to introduce Christianity to Yemen to establish political and economic influence in the region. Their trade routes passed through Yemen, connecting the Arabian Gulf and the Red Sea. Meanwhile, the Jewish presence in Yemen grew as Jews fleeing Roman persecution, especially after the destruction of the Second Temple in Jerusalem in 70 CE, sought asylum there.

As the influence of the Jewish community in Yemen increased, tensions arose with Roman Christians. Fueled by a spirit of revenge, the Jewish king Dhu Nuwas al-Himyari of the Al-Diyaniyya dynasty persecuted Christians who refused to convert to Judaism. He famously dug trenches for them and set them on fire, a brutal act that marked a dark period in Yemen's history.The Beginning and the End, Part Two, The Story of the People of the Groove

The Abyssinians invaded Yemen in 533 CE with the goal of eliminating their Persian rivals and reclaiming control of the trade routes. Their leader, Aryat, assumed power after overthrowing the Himyarite King Dhu Nuwas. In 535 CE, Abraha al-Habashi declared himself king of Yemen after breaking away from the Axumite state in Abyssinia.

Abraha ruled independently and sought to spread Christianity throughout the Arabian Peninsula. He aimed to redirect Arab pilgrimage from Mecca to a grand cathedral he built in Sanaa, known as Al-Qalis. In 570 CE, he famously attempted to invade Mecca, an event remembered as the "Year of the Elephant." Abraha was later succeeded by his son, Axum.

Saif bin Dhi Yazan Al-Himyari, a prominent noble of Himyar, sought assistance from the Persians to expel the Abyssinians from Yemen. With Persian support, Saif bin Dhi Yazan successfully ended the 72-year Abyssinian rule over Yemen. However, this victory brought Yemen under Persian control, marking the beginning of a new colonial era.Majmal al-Tarikh, p. 171

During this period, Yemen experienced political, tribal, religious, and intellectual fragmentation. Sana'a and its surrounding regions were directly subjected to Persian rule, with the Persians forming a distinct class known as the "Sons." Meanwhile, Yemeni regions beyond Persian control remained mired in conflicts and tribal disputes, a state of unrest that persisted until the emergence of Islam.

Muhammad's era

Several researchers believe that the rapid conversion of the Himyarites, Hamdan, and Hadhramaut tribes to Islam can be attributed to their longstanding adherence to a monotheistic religion prior to Islam. However, neither Mu'adh ibn Jabal, Ali ibn Abi Talib, nor Abu Musa Al-Ash’ari stayed long in these regions before the tribes embraced Islam.Israel Abu Dhu’ayb, Ka'b Al-Ahbar Review Mahmoud Abbasi Al-Sharq Cooperative Press, Jerusalem, p. 25

The Bedouin tribes, such as Kinda and Madhhaj, took a different stance during this period. A battle erupted between the Hamdan tribe and the Murad branch of Madhhaj, during which Madhhaj suffered defeat at the hands of Hamdan. Despite their historical ties, Kinda and Madhhaj faced internal tensions. Farwa bin Al-Musayk Al-Muradi, a leader of the Madhhaj tribe, reportedly severed ties with the kings of the Kingdom of Kinda after they betrayed him during the battle.
