Court. Under Emperor Constantine VIII he held the post of urban prefect of Constantinople, which made him the formal head of the Senate and one of the emperor's chief lieutenants. Reign Late in 1028, Constantine VIII lay on his deathbed. Wishing to secure the Macedonian dynasty, but having no son, he summoned Constantine Dalassenos from Antioch to marry his oldest daughter, Zoë. Dalassenos, the doux of Antioch, was an experienced military commander, influential patrician, and unswervingly loyal to the ruling house. The emperor's advisors preferred not to have a strong military figure as the new emperor, and persuaded the Emperor to choose Romanos instead, as a potentially more pliable and certainly less travelled candidate. Constantine VIII forced Romanos to divorce his wife (who was sent to a monastery) and to marry Zoë, aged 50 at the time; Romanos was 60. The marriage took place on 9 November 1028, and on the same ceremony Romanos was proclaimed caesar. Three days later, on 11 November, Constantine died of illness. 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. In 1030 he resolved to lead an army in person against the Mirdasids of Aleppo, despite their having accepted the Byzantines as overlords, with disastrous results. The army camped at a waterless site and its scouts were ambushed. An attack by the Byzantine cavalry was defeated. That night Romanos held an imperial council at which the demoralised Byzantines resolved to abandon the campaign and return to Byzantine territory. Romanos
