Silvan is a city in the Diyarbakır Province of Turkey. Its population is 41,451.HistorySilvan has been identified by several scholars as one of two possible locations of Tigranakert, the ancient capital of the Kingdom of Armenia, which was built by King Tigran the Great and named in his honor.Roman EraIn 69 BCE, the army of Republican Rome defeated Tigran's troops in the battle of Tigranocerta. The city lost its importance as a thriving center for trade and Hellenistic culture in the following decades. In 387 CE, with the Peace of Acilisene, Tigranakert was made part of the Byzantine Empire.Diocese of MartyropolisAround 400 CE, the city's bishop, Marutha (later, saint Maruthas), brought a large number of relics back from Sassanid Persia. These were relics of Christian martyrs persecuted under Sassanid rule. For this reason it was renamed Martyropolis, "city of the martyrs." Following the reforms of Justinian I (rule 527–565), the city was made the capital of the province of Fourth Armenia. The city suffered heavily in the Battle of Martyropolis in 588 CE, but soon prospered again.
