Romanos has been recorded as a well meaning but ineffective emperor. He disorganised the tax system and undermined the military, personally leading a disastrous military expedition against Aleppo. He fell out with his wife and foiled several attempts on his throne, including two which revolved around his sister-in-law Theodora. He spent large amounts on the construction and repair of churches and monasteries. He died after six years on the throne, allegedly murdered, and was succeeded by his wife's young lover, Michael IV.
