Cauci

100 CE – 200 CE (approx.)

People of Ireland's east coast recorded only in Ptolemy's 2nd-century Geography, whose name echoes the Chauci of northern Germany.

Origins

The Cauci are known solely from Ptolemy's Geography of about 150, which drew on earlier reports by merchants and sailors. He places them on the east coast of Ireland, between the Eblani to the north and the Manapii to the south, roughly in the area of modern Dublin and Wicklow.

Rule and society

Nothing is recorded of their rulers, settlements or way of life. Their name closely resembles that of the Chauci, a Germanic people of the North Sea coast, which has prompted speculation about settlers or traders from the Continent, but most scholars treat the likeness as coincidence or a copying error.

Decline and legacy

No later source mentions them, and Irish tradition preserves no matching name. Their region later formed part of the Kingdom of Leinster.

Few sources survive for this state; details are uncertain.
