When the revolution of 1360 broke out the city of Louvain was, in name and in fact, the first city of Brabant. The cluster of cottages around the church which Lambert Balderic had founded on the banks of the Dyle three centuries before had grown into a great industrial and commercial centre, with a population of something like 70,000 souls. In the number of its inhabitants, in the extent of its trade, in political influence, in social prestige, in the splendour of its public and private buildings, it eclipsed at this time every town in the duchy. Among the burgher nobles of Brabant none were so rich and so powerful as the Petermen of Louvain: not only did they enjoy the dignities and privileges common to all patricians, but they participated, as we have seen, in the immunities of the Church, and that, without being irked by correlative duties. Also, they shone alone, there were no brighter stars in their firmament: the Sovereign had long ago left Louvain, and there were no Court nobles to rival their glory or to dispute their right to pre-eminence. As they were human, of course they were puffed up--proud of their wealth, proud of their race, proud of their solitary grandeur and of the consideration which these things gave them; exceedingly jealous of their privileges, very swift to resent any attempt at aggression, whether it came from above or from below; and of course they contemned the seething mass of shame and misery beneath them--a mutinous army of workers, many thousands strong, as eager and determined to obtain liberty as their masters were to keep them in bondage. Such was the social complexion of Louvain during the fifty years which preceded the revolution of 1360. Paint the picture on a smaller scale and in less glaring colours, and you will have some idea of the social complexion of Brussels during the same period.
