All The Post-Classical and Medieval World

The largest single group in this tree, 23 of 125 events, spanning roughly 476 to 1453 CE: the great charters and parliaments of medieval England, the Crusades and their individual campaigns, the Mongol conquests, the Black Death, sieges from Baghdad to Vienna's medieval predecessor conflicts, and the 1453 fall of Constantinople that conventionally closes the period. Belongs here: an event dated within this atlas's own Post-Classical and Medieval Period era window, or tied to it by a live In Era relationship already recorded on the entity. Does not belong here: an event from the fourteenth-century Renaissance onward once its own significance is more naturally read as an early modern one, grouped under The Early Modern World.
