The Frank kings on several occasions evinced a desire that communications favourable to trade should be re-established in their dominions.  We find, for instance, Chilperic making treaties with Eastern emperors in favour of the merchants of Agde and Marseilles, Queen Brunehaut making viaducts worthy of the Romans, and which still bear her name, and Dagobert opening at St. Denis free fairs—­that is to say, free, or nearly so, from all tolls and taxes—­to which goods, both agricultural and manufactured, were sent from every corner of Europe and the known world, to be afterwards distributed through the towns and provinces by the enterprise of internal commerce.

After the reign of Dagobert, commerce again declined without positively ceasing, for the revolution, which transferred the power of the kings to the mayors of the palace was not of a nature to exhaust the resources of public prosperity; and a charter of 710 proves that the merchants of Saxony, England, Normandy, and even Hungary, still flocked to the fairs of St. Denis.

Under the powerful and administrative hand of Charlemagne, the roads being better kept up, and the rivers being made more navigable, commerce became safe and more general; the coasts were protected from piratical incursions; lighthouses were erected at dangerous points, to prevent shipwrecks; and treaties of commerce with foreign nations, including even the most distant, guaranteed the liberty and security of French traders abroad.

Under the weak successors of this monarch, notwithstanding their many efforts, commerce was again subjected to all sorts of injustice and extortions, and all its safeguards were rapidly destroyed.  The Moors in the south, and the Normans in the north, appeared to desire to destroy everything which came in their way, and already Marseilles, in 838, was taken and pillaged by the Greeks.  The constant altercations between the sons of Louis le Debonnaire and their unfortunate father, their jealousies amongst themselves, and their fratricidal wars, increased the measure of public calamity, so that soon, overrun by foreign enemies and destroyed by her own sons, France became a vast field of disorder and desolation.

The Church, which alone possessed some social influence, never ceased to use its authority in endeavouring to remedy this miserable state of things; but episcopal edicts, papal anathemas, and decrees of councils, had only a partial effect at this unhappy period.  At any moment agricultural and commercial operations were liable to be interrupted, if not completely ruined, by the violence of a wild and rapacious soldiery; at every step the roads, often impassable, were intercepted by toll-bars for some due of a vexatious nature, besides being continually infested by bands of brigands, who carried off the merchandise and murdered those few merchants who were so bold as to attempt to continue their business.  It was the Church, occupied as she was with the interests of civilisation, who again
