Marcianopolis

Roman Emperor Trajan renamed the ancient city of Parthenopolis after the Second Dacian War, which ended in 106.

Marcianopolis's prosperity under the Severan Dynasty was ended by a Gothic raid in 248–249 and subsequent barbarian invasions from the north.

[2] Under Emperor Diocletian Marcianopolis became the centre of the province Moesia Secunda of the Diocese of Thrace, and was rebuilt thoroughly in the late 3rd and early 4th century.

During Emperor Valens' conflict with the Goths (366–369), Marcianopolis was a temporary capital of the empire and the largest city of Thrace according to a source from the period.

[6] Despite the regular barbarian attacks, Marcianopolis remained an important centre until an Avar raid finally destroyed it in 614–615, although it still continued to be mentioned on maps until much later.
