The Moesi (/ˈmiːsaɪ/ or /ˈmiːzaɪ/; Greek: Μοισοί) was a Thracian tribe which inhabited present day Northern Bulgaria and Serbia, which gave its name to the Roman province of Moesia after its defeat in 29 BC. Moesia was first established as a separate province in 45–46 AD.The Moesi were formed out of the 14th century BC Brnjica culture. Thracologists suggest that the Moesi may have spoken a language or dialect intermediary between Dacian and Thracian. Little is known about them prior to 29 BC.
