Mithridatic Wars
With the eastwards expansion of the Roman Republic during the Mithridatic Wars, the Kingdom of Armenia, under the Artaxiad dynasty, was made a Roman protectorate by Pompey in 66/65 BC. For the next 100 years, Armenia remained under Roman influence. Towards the middle of the 1st century AD, the rising Parthian influence disputed Roman supremacy, which was re-established by the campaigns of Gnaeus Domitius Corbulo.
