Pangani, Tanzania

During the Swahili era (1250–1550 CE), interactions between indigenous tribes of the Pangani coast and communities in the Indian Ocean took place, but at a minor level. Thus, the "Golden Age" of the Swahili (1250/1350-1550 C.E., but especially the earlier centuries within this range) influenced littoral settlers in northeastern Tanzania, although not nearly to the extent felt at Kilwa on the southern Swahili coast (where the gold trade flourished 1200-1350 C.E.) or at Mombasa and Malindi in Kenya. Late in this era, Tongoni as well as Swahili towns on Tanga Island (in the bay near Tanga Town) with monumental Swahili architecture began to grow in importance.

Archaeologists have also found the remains of small 15th century Swahili settlements on the bluffs just north of Pangani at Muhembo, According to the research, Pangani Bay's first inhabitant's Zanjian traditions served as the cradle of later Swahili culture. From the Zanjian to the Swahili periods, local people continued to practise the majority of their pottery, trading, and culinary practises. Minor alterations are also discernible, most likely due to ongoing interactions with bordering groups along the shore. From the Zanjian to the Swahili periods, pottery with comparable form and ornamentation was employed.

Shellfish evidence reveals patterns of food collecting by the first inhabitants and the kinds of foods that were consumed, suggesting both change and continuity. The discovery of Sasanian Islamic wares from the Persian Gulf during the Zanjian period and black-and-yellow ceramics from the Red Sea during the Swahili eras is evidence of the old maritime trade history in Pangani Bay. The pottery in Zanjian and Swahili villages in Pangani Bay shared characteristics with that of sites on the East African coast (Shanga, Kilwa, and Kaole), as well as its hinterland (Mombo), in addition to the recognised internal cultural continuity. Such evidence suggests that the people of Pangani Bay are still connected to other communities in East Africa on a regional level.

The southern Swahili coast (south of Tanga Town) is thought to have developed a different tradition from the northern coast (from Mombasa to the Lamu Archipelago in Kenya) before 1250 C.E. Due to a shift in Islamic influence (from the Persian Gulf to the Red Sea) that brought people together and encouraged settlement growth and expansion, the northern shore dominated the economy during this time. on this model, resurrected leadership anchored on Islamic doctrine, iconography, and emulation increased trade monopolies and sparked close ties with other groups in the Indian Ocean through trade. During this time, it is likely that a rigid, emic idea of the African hinterland developed as wealthy coastal Swahili town dwellers (waungwana) saw the need to set themselves apart from people who lived in the interior in order to consolidate their authority and safeguard expanding trade monopolies.

Surface investigations revealed 18 Swahili sites, including Mnyongeni, Mtakani, and Kumbamtoni (1250–1550 C.E.). Villagers in Muhembo and Tongoni were constructing coral structures and going to mosques for prayer by 1400 C.E. These were the two biggest towns in their respective regions at the time. Other community members (from Muhembo and Tongoni) resided in distant wattle-and-daub homes. Foreign contacts, which may be seen in the archaeological record in the form of Asian ceramics and glass beads, had a significant impact on the formation of identity borders. For example, 62 of 81 (75.3%) of the beads found during excavations at these sites—92 of 108 (85.2%) at Muhembo (Site 37 in Survey Unit 4); and Tongoni—are of foreign (glass) provenance. Among other things, locals created iron tools, textiles, nonglass beads, and ceramics.

The situation along the coast was different after 1550 C.E. In contrast to Mombasa, the majority of coastal cities shrank in population, lost their once-dominant status, or even fell into ruin. By 1600 C.E. and 1850 C.E., respectively, pottery from Post-Swahili and Post-Post-Swahili settlements were widespread. The initial phase of these at Pangani was characterised by diffuse settlement. Compared to sites from earlier, Swahili times, those that included only Post-Swahili materials were found during the survey to be relatively smaller. On the other hand, findings from sites containing mostly Swahili artefacts are scarcely any Post-Swahili remains.
