A Gaulish people, the Medulli belonged to the group of mountain tribes controlling access to high Alps passes, along with the Centrones in Tarentaise Valley and the Salassi in Aosta Valley, especially for the trade of metals (tin, iron and copper). They were established in the middle valleys of the Maurienne, the higher parts being inhabited by the Graioceli.
Their name came from Medu = "mead". They were integrated in the Province of Cottian Alps in 16 BCE.
A branch of the Medulli moved near Bordeaux, in the area named Médoc after them.
