The Cotini , sometimes spelled Gotini (because it is found in some manuscript copies of Tacitus), were a Gaulish tribe living during Roman times in the mountains approximately near the modern borders of the Czech Republic, Poland, and Slovakia.
[1] (Tacitus clearly distinguishes the Gotini from the similarly named Gotones, whom he discusses in the immediately following passage.
Although the Gotini lived in the midst of Suevic peoples, in geographical Germania, they were not Germanic in their language.
He reports that around 172 AD the Cotini offered to attack the Marcomanni in exchange for a grant of land, then ensured their own destruction by failing to uphold their end of the bargain.
[6] It has been suggested that to punish them, Marcus Aurelius moved all or some of the Cotini to Lower Pannonia, which happened not later than 180 AD.
