Of great importance in early times, in the 2nd century BC Tyras fell under the dominion of native kings whose names appear on its coins, and it was destroyed by the Getae about 50 BC.[1]
In 56 AD, it seems to have been restored by the Romans under Nero and henceforth formed part of the province of Lower Moesia. There exists a series of its coins with heads of emperors from Domitian to Alexander Severus.[1]
Indeed, the autonomous minting of coins in the city lasted from the time of the emperor Domitian (81 AD) up to the end of the reign of the emperor Alexander Severus (235 AD) with few breaks. The coins of Tyras of this period were of copper with the portraits of the members of the Imperial house for the province of the Roman Empire.
In 201 CE, Septimius Severus and Caracalla granted the inhabitants of the city the right to engage in duty-free trade.[2]
Soon after the time of Alexander Severus, it was partially destroyed by the Goths, but archaeological findings show that Romans remained there until the end of the 4th century under Theodosius I. Later the Byzantines renamed the city, destroyed by barbarian invasions, with the new name Maurokastron, "black fort".
Its government was in the hands of five archons, a senate, a popular assembly and a registrar. The images on its coins suggest a trade in wheat, wine and fish. The few inscriptions are also mostly concerned with trade.[1]
Remains of the city are scant, as its site has been covered by the great medieval fortress called by the GenoeseMaurocastro (and later Akkerman/Cetatea Albă).[1]
