Tigranes the Great
Nicomedes appealed to the Roman Senate, which decreed that Mithridates be removed from Cappadocia and Nicomedes be removed from Paphlagonia and the Senate appointed Ariobarzanes I of Cappadocia as King of Cappadocia. Mithridates prompted his son-in-law Tigranes the Great of Armenia to invade Cappadocia and remove Ariobarzanes.
