In medieval Christian symbolism the pentagram represents the five wounds of Christ and appears in works such as the 14th-century poem Sir Gawain and the Green Knight, where it is called the 'endless knot' and stands for the five virtues of knighthood.

After the mass conversions, a large population of New Christians lived in Spain and Portugal, some devoutly Catholic and some secretly keeping Jewish practices.

c. 1400 Rival sultanates of Pate, Lamu, and Malindi 0 cit. The northern coast was a patchwork of competing city-states, each with its own ruling house. The island town of Pate, whose story is told in the much-debated Pate Chronicle, contended with Lamu and Malindi for trade and primacy over centuries. The chronicle's early dates and dynastic claims are treated with caution by historians, who read it alongside archaeology. Alliances shifted constantly, and no single town held the coast for long. diplomacy / politics ●

c. 1400 The Sirikwa and their cattle hollows contested 0 cit. Across the western highlands lie thousands of Sirikwa holes, saucer-shaped hollows that were once fortified cattle pens attached to homesteads, in use from roughly the twelfth to the eighteenth centuries. They mark a settled herding society skilled at guarding stock against raiders. Whether the Sirikwa were direct Kalenjin ancestors or a separate people later absorbed is still argued, so their identity stays contested. economy / society ●●
