The new emperor was eager to make his mark as a ruler, but was mostly ineffectual in his enterprises. He idealised Marcus Aurelius, aspiring to be a new philosopher king, and similarly sought to imitate the military prowess of Trajan. He spent large sums on new buildings and in endowing churches and monasteries. He endeavoured to relieve the pressure of taxation on the aristocracy, which undermined the finances of the state. Previous emperors had attempted to control the privileges of the nobles over the common people. Coming from the aristocracy himself, Romanos III abandoned this policy. This failure to stand up to the aristocrats allowed them to exploit the rural mass of landed peasantry, who increasingly fell into a condition of serfdom. This in turn undermined the traditional recruiting base of the Byzantine army. The combination of a reduced tax base and fewer native-born troops had long-term consequences. As revenue declined, the subsequent impoverishment of the state weakened the military's recruitment power still further.
