The Bantu Expansion stands for the concurrent dispersal of Bantu languages and Bantu-speaking people from an ancestral homeland situated in the Grassfields region in the borderland between current-day Nigeria and Cameroon. During their initial migration across most of Central, Eastern, and Southern Africa, which took place between approximately 5,000 and 1,500 years ago, Bantu speech communities not only introduced new languages in the areas where they immigrated but also new lifestyles, in which initially technological innovations such as pottery making and the use of large stone tools played an important role as did subsequently also farming and metallurgy. Wherever early Bantu speakers started to develop a sedentary way of life, they left an archaeologically visible culture. Once settled, Bantu-speaking newcomers strongly interacted with autochthonous hunter-gatherers, as is still visible in the gene pool and/or the languages of certain present-day Bantu speech communities. The driving forces behind what is the principal linguistic, cultural, and demographic process in Late Holocene Africa are still a matter of debate, but it is increasingly accepted that the climate-induced destruction of the rainforest in West Central Africa around 2,500 years ago gave a boost to the Bantu Expansion.
The Horn of Africa has an exceptional cultural heritage, starting with its manuscript sources, which are among the most important on the continent. It is a heritage that is rich but scattered throughout the region and not always easily accessible, prompting researchers to rely on cutting-edge technology. Since the 1970s, photography and microfilm have been key for preserving this especially valuable heritage. In the Horn of Africa, the “digital turn” has been the latest development in the close relationship between technology and research. For Ethiopian manuscript studies, the advent of digitization has meant more than simply improving old techniques. A new generation of projects is experimenting with innovative methods of research made possible by digital technology. The purpose is no longer just to provide digital copies of manuscripts but to explore the possibilities that computerization offers to study documents and other historical sources.
Increasingly competitive prices and low operating costs have made the digital revolution attractive even for African institutions, which, in recent years, have sought answers to the pressing needs of preserving and enhancing their historical sources. These technological developments have significantly broadened the range of sources investigated. While important, manuscripts represent only a part of the documentary heritage of the Horn of Africa. Numerous archives and a long-overlooked print culture offer equally interesting access points for studying the region.
The experience gained, though temporally circumscribed, has highlighted a number of more or less predictable problems. The projects to date, although they have often yielded only partial results, have highlighted the wealth of sources still present in the Horn of Africa and the way in which digital technology is making a valuable contribution to their preservation. Access remains perhaps the most critical issue. In the Horn of Africa, as in other African regions, digitization does not necessarily lead to Internet access.
The Red Terror was a period of intense political and inter-communal violence in revolutionary Ethiopia during the late 1970s. This violence erupted two years after the revolution of 1974 and was concentrated in the cities and towns of Ethiopia, particularly in Addis Ababa, Gondar, Mekele, Asmara, and Dessie. In the struggle over the direction and ownership of the revolution, opposition groups of the radical left violently opposed a military regime that itself came to embrace and promulgate Marxist-Leninist language and policies, and that relied heavily on the use of armed force to stifle dissent. While much of the violence was carried out by security personnel, the delegation of the state’s means and instruments of violence to newly formed militias and to armed citizens was a defining feature of the Red Terror. The number of casualties and victims of the Red Terror remains heavily contested and is subject to divergent counting criteria and to definitions of the Terror’s scope in relation to other concurrent conflicts in the region, such as the Eritrean and Tigrayan civil wars; plausible figures suggest more than 50,000 deaths, in addition to many more who were subjected to torture, exile, personal losses, and other forms of violence. To this day, the Red Terror constitutes a period that is remembered in Ethiopia as much for the forms of its violence as for the extent of its harm. Its ramifications, from the support it triggered for the ethno-nationalist insurgencies that overthrew the military regime in 1991, to its role in the emergence of a sizeable Ethiopian diaspora, make the Red Terror an episode of defining and lasting significance in the modern history of Ethiopia.

The inception of agriculture in eastern Africa is a major topic of discussion among Africanist archaeologists, although very sparse evidence exists. Questions range from whether domestication was a local invention or whether it was introduced from the Near East, Asia, or elsewhere outside of Africa. These questions have remained unanswered because wild progenitors and models of the spread of African domesticates are yet to be established using undisputable data. The paucity of direct data has therefore necessitated the use of objects of material culture such as pottery, beads, burial cairns, architectural structures, and so on as indicators of pastoralism and cereal farming. In addition to the origins of African domesticates, research in eastern Africa has concerned itself with questions of farming technologies from later archaeological and historical times to the present. The remains of elaborate farming systems with extensive irrigation networks have drawn considerable attention. Though not unchanged, some of these farming systems remain in contemporary use in Kenya, Tanzania, and Ethiopia.
The history of Islam in East Africa stretches back to around 1000 CE. Until the mid-20th century, it remained largely confined to the coast and closely bound up with the history of the Swahili towns situated on it. The Swahili language remains central to many East African Muslims, hence the occasionally heard phrase, “Swahili Islam.” East African Muslims are mostly Shafiites and some belong to Sufi orders, especially Qadiriyya and Shadhiliyya. Since c. 1850, Islam, with many variations in ritual, has become the religion of speakers of a multitude of languages across the region, second only to Christianity. The region’s independent nation-states initially promised equality for all religions within a secular order. Since c. 1990, though, the minority status of East African Muslims has fed into a multitude of grievances related to the region’s economic and political impasses. This situation has led to growing movements of Islamic preaching and activism, supported by increased contacts with congregations elsewhere in the Indian Ocean. At times, they have influenced electoral politics, especially in Zanzibar, where Islamic activism resonates with fear of marginalization by the mainland. In Kenya, Somali-influenced Islamist terrorists committed a series of atrocities in the 2010s. East African governments, in turn, have been proactive in tracking and disrupting such networks, and in Kenya, the government engaged in targeted assassination. Nevertheless, peaceful coexistence between Muslims and adherents of other religions remains the norm in East Africa, and its dynamics are often poorly understood.

In the mid-16th century, the Ottoman empire expanded to encompass parts of the modern Sudan, Eritrea, and the Ethiopian borderlands, forming the Ottoman province of Habeş. The Ottomans also provided aid to their ally Ahmad Grañ in his jihad against Ethiopia and fought with the Funj sultanate of Sinnar for control of the Nile valley, where Ottoman territories briefly extended south as far as the Third Cataract. After 1579, Ottoman control was limited to the Red Sea coast, in particular the ports of Massawa and Suakin, which remained loosely under Ottoman rule until the 19th century, when they were transferred to Egypt, nominally an Ottoman vassal but effectively independent. Politically, Ottoman influence was felt much more broadly in northeast Africa in places as distant as Mogadishu, at least nominally recognized Ottoman suzerainty.

Popular politics have influenced the development of East Africa’s political institutions from roughly two millennia ago up to contemporary times. Among the discernible political dynamics over this time period were pressures to include or exclude peoples from key institutions of belonging, the decisive role of patron–client relationships across all political institutions, the role of generational conflict, the source of political authority based on command of the visible and invisible worlds, and the changing role of indigeneity and “first-comer” status claims. These dynamics can all be found at work in the development of conventional political structures that span this time frame—that is, from the small chieftaincies and kingdoms of the precolonial era; to cults of public healing and medicine making; to engagement with European colonial institutions and the 20th-century creation of “traditional” indigenous authorities; to the growth of associational life that led to political parties, one-party states, and their postliberalization successors. Yet there was also tremendous diversity of these experiences across East Africa, which goes some way toward explaining the differences not only among the region’s contemporary nation-states but even within those nation-states. Popular pressures for inclusion either resulted in the expansion of existing political institutions or created demands for new institutions that directly challenged the exclusionary and often brittle existing political structures.
The East African coast is an interface between the continental world of Africa and the maritime world of the Indian Ocean, and the monsoons provided a convenient wind system to link them. It was inhabited by a littoral society that was best placed to play a leading role in economic, social, and cultural interaction, including intermarriage, between the two worlds. Its written history goes back at least to the beginning of the Contemporary Era, and it can be termed Swahili from the beginning of the second millennium when this branch of the Bantu languages spread down the coast to give it linguistic unity. Its speakers were organized in towns and villages from southern Somalia to northern Mozambique, which developed into city-states when there were major upturns in international trade and were integrated in the wider Indian Ocean world. The citizens spoke an “elegant” language that was further embellished through its interactions with Arabic and other Indian Ocean languages and literature. Islam spread with that trade, and mosques became a prominent part of the archaeological remains along the Swahili coast. In the process, the Swahili became thoroughly cosmopolitan. Any attempt to disentangle the different strands, “oriental” or “African”—which are two sides of the dense cultural fabric of the littoral people—is bound to be futile. They are two sides of the Swahili coin. This civilization was partially disrupted by the entry of the Portuguese in the 16th century when they tried to divert the spice trade to their channel around the Cape of Good Hope, but it revived during the 18th and 19th centuries.
