Trajan’s uncompromising attitude in fight for Armenia
The throne of Armenia, a country at the confluence of Roman and Parthian influences, was informally consulted and established between the two then powers over the years. When in 110 CE king Osroes I of the Parthians appointed his nephew Axidares, son of former king Pacorus II, to the throne of Armenia, there was a breach of an unwritten rule, and Rome was not asked to accept the new candidacy.
