The colonisation theory, in which is considered to have been a colony of
Sheba, was first articulated by
Carlo Conti Rossini based on the
Hamitic hypothesis in the early 20th century, and was widely accepted by historians and entered popular historical understanding. However from the 1970s onwards, epigraphic, linguistic, and more recently archaeological evidence and re-interpretation indicated that developments previously attributed to South Arabian contact were indigenous in origin and had occurred at an earlier date, Scholars of
South Arabian archaeology and
epigraphy tend to favour a migration and/or colonisation, while scholars of
African archaeology tend to stress an indigenous origin.
David Phillipson writes that other polities, indicated by inscriptions mentioning non- rulers, were likely short-lived and localised. Some have questioned whether '''' was the name of a state, a tribe, a region, or a specific location. Sabaean inscriptions were found in
Somaliland and
Puntland, as well as a Sabaean temple whose inscriptions say its construction was ordered by the admiral of Sheba's fleet. In 2025 said "we can perhaps discern two different models: a proper colonialist one along the northern Somali seaboard, with direct intervention of the state and aimed at the extraction of resources, and a diasporic model in the northern Horn, led by élites who soon mixed with local people, while maintaining ties with their ancestral homeland". He notes that differences between the
nomadic pastoralist groups in Somalia and South Arabians were probably too great for assimilation.
Large migration and/or colonisation In 2011,
Sarah Japp, ,
Holger Hitgen, and
Mike Schnelle authored a paper which analysed evidence from
Yeha and
Hawelti. They find the evidence of Sabaean influence too compelling to be explained by the presence of individuals or small groups, and note that settlers are more associated with social, political, cultural, and religious change than merchants and tradesmen, leading them to conclude that there was a large migration of Sabaean groups. They relate this to
Sheba's expansionism during the 8th and 7th centuries BCE, and their policy to settle Sabaeans in conquered territories, proposing that Sabaeans founded an autonomous realm called and
acculturation took place between Sabaean settlers and the indigenous population. ==References==
