Who & why: for roughly nine centuries before Otto I's coronation, "Germany" is not a place with a government but a linguistic and cultural zone of independent tribes east of the Rhine and north of the Danube — first in intermittent contact and conflict with Rome, then gradually consolidating under Frankish rule from the 5th century onward. Charlemagne, a Frank, is crowned Holy Roman Emperor in 800, uniting most of the Germanic-speaking lands (plus Gaul and Italy) under one crown for the first time; the Carolingian Empire's 843 partition among his grandsons leaves East Francia as the direct territorial ancestor of the kingdom Otto I inherits in 936 and crowns into an empire in 962.
What it represents: no flag from this era survives or was likely ever created in any modern sense — shown here honestly blank. Tribes carried standards (the Romans record animal totems and carved wooden or bronze figures on poles) but nothing resembling a woven national flag.
World context: this span runs alongside the building of Rome's Colosseum (70–80 CE) and Pantheon (126 CE), the height and slow decline of the Han dynasty in China, the life of Muhammad and the rapid 7th-century Arab conquests, and Charlemagne's own 800 coronation in Rome — a deliberate echo of the fallen Western Roman Empire three centuries after its last emperor was deposed in 476.
