Deultum — A settlement in Thrace
Deultum was founded as an emporium of Apollonia Pontica in the 7th century BC. From the 6th century to the 4th century BC, the settlement served as an important place of trade between Thracians and Greeks.

It was annexed to the Roman Empire in 46 AD and became part of the province of Thrace. The construction of a colonia for veterans of the VIII Augusta legion at Deultum was likely planned prior to 69 AD, but was delayed due to the eruption of civil war of 69 AD. The veterans may have been settled at Deultum due to its proximity to the neighbouring region of Moesia, where VIII Augusta was formerly based.

During the Gothic War of 376–382, a Roman army was defeated by a Gothic raiding party outside Deultum, and the city was sacked. Deultum was later rebuilt on a smaller scale, and, in the second half of the 5th century, new walls were constructed and all unprotected buildings were demolished to ensure hostile forces did not use them as cover.
