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. Estimates vary, with approximately 200 tribes in Yemen, although some reports list more than 400. Yemen is notable as 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.
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. 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."
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. 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. 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.
