Rouen had not remained entirely submissive to the Lion of Justice. In 1109 the King of France encouraged yet another rising of the citizens in Rouen and elsewhere against feudal power. And after the wreck of the White Ship, Fulk of Anjou took the opportunity to push the claims of Duke Robert's son both in England and Normandy, but the rebels were badly beaten at Bourgtheroulde (between Seine and Rille), and the Lion of Justice held a court in Rouen to judge them. Some were imprisoned in his Tower by the Seine, and some in Gloucester, while a satiric poet, named Luke of Barre, paid the penalty of being a pioneer in scoffing politics by having his eyes put out. At Henry's death in 1135, Matilda's infant heir was still very young at Le Mans, and the usual anarchy followed both in England and in Normandy that was inevitable when the direct male line of Norman Dukes died out. Of the two countries Normandy had perhaps the fate that was hardest to bear, for it was better to be ruled by any one than a Count of that Maine, with whom, as with an equal, so many centuries of battles had been fought. But the strong stock of Anjou and Maine soon took advantage of the weakness of the Northern Duchy, and in 1144 Geoffrey Plantagenet entered Rouen in triumph.
"Neustria concutitur fulgure tacta novo."
To an inheritance so rich already, the boy Henry Plantagenet added all the dominions of Eleanor of Poitou by marriage, and after the anarchy of Stephen's reign in England had passed over, the Angevin Empire began from the Pyrenees to the Firth of Forth. At ten years old the second Henry had been recognised by Rouen as her duke, and it can be easily understood that the citizens used every advantage it was possible to win from the years of his minority, and from the days of uncertain authority before it. Already under Henri Beauclerc the municipality of Rouen had obtained ampler recognition than before. Its population increased accordingly, and was augmented by the extension of freedom to a considerable number of serfs. The bounds of the city itself were enlarged, and from the fact that a fire is recorded (in November 1131) to have destroyed the Hôtel de Ville, near the Porte Massacre, in the Rue de la Grosse Horloge, we may gather that the municipality, whose rights in property were recognised, had been able to secure a common meeting-place for the discussion of its civic business. By 1150 these meetings had resulted in a league, definitely made by the burgesses, to defend their rights against all feudal encroachments, a league which very nearly deserves that name of "Commune" at last, which was apparently first given in Normandy to Eu and to St. Quentin. Geoffrey Plantagenet, during his government of the Duchy for his son, had recognised the strength of this civic movement, by confirming the privileges of the citizens, and favouring the growth of this industrial corporation. In May of that same year the first law court of the town, as opposed to feudal or ecclesiastical justice, was also established, and called the Vicomté de l'Eau. It had the charge of all civil and criminal cases by river and by land, and kept the standard of the weights and measures. Its importance may be judged from the fact that in the hands of the merchants of Rouen was the monopoly of all wines sent by Seine or sea towards the north. The Confrèrie of these "Marchands de l'eau" had been accorded a special port, known as Dunegate, at Thames' mouth, by Edward the Confessor, and their monopoly extended also to the whole trade between Normandy and Ireland, a trade they kept until the reign of Philip Augustus.
