A fresh series of conflicts began in the 2nd century AD, during which the Romans consistently held the upper hand over Parthia. The Emperor Trajan invaded Armenia and Mesopotamia during 114 and 115 and annexed them as Roman provinces. He captured the Parthian capital, Ctesiphon, before sailing downriver to the Persian Gulf. However, uprisings erupted in 115 AD in the occupied Parthian territories, while a major Jewish revolt broke out in Roman territory, severely stretching Roman military resources. Parthian forces attacked key Roman positions, and the Roman garrisons at Seleucia, Nisibis and Edessa were expelled by the local inhabitants. Trajan subdued the rebels in Mesopotamia, but having installed the Parthian prince Parthamaspates on the throne as a client ruler, he withdrew his armies and returned to Syria. Trajan died in 117, before he was able to reorganize and consolidate Roman control over the Parthian provinces.* Sicker (2000), 167–168</ref>
