The burghers began to be disquieted, and to wax wroth.

During a trip the bishop made to England, they offered a great deal of money to the clergy and knights who ruled in his absence, if they would consent to recognize by a genuine Act the right of the commonalty of the inhabitants to be governed by authorities of their own choice.
"The clergy and knights," says a contemporary chronicler, "came to an agreement with the common folk in hopes of enriching themselves in a speedy and easy fashion." A commune was therefore set up and proclaimed at Laon, on the model of that of Noyon, and invested with effective powers.

The bishop, on his return, was very wroth, and for some days abstained from re-entering the town.

But the burghers acted with him, as they had with his clergy and the knights: they offered him so large a sum of money that "it was enough," says Guibert of Nogent, "to appease the tempest of his words." He accepted the commune, and swore to respect it.
The burghers wished to have a higher warranty; so they sent to Paris, to King Louis the Fat, a deputation laden with rich presents.

"The king," says the chronicler, "won over by this plebeian bounty, confirmed the commune by his own oath," and the deputation took back to Laon their charter sealed with the great seal of the crown, and augmented by two articles to the following purport: "The folks of Laon shall not be liable to be forced to law away from their town; if the king have a suit against any one amongst them, justice shall be done him in the episcopal court.
For these advantages, and others further granted to the aforesaid inhabitants by the king's munificence, the folks of the commune have covenanted to give the king, besides the old plenary court dues, and man-and-horse dues [dues paid for exemption from active service in case of war], three lodgings a year, if he come to the town, and, if he do not come, they will pay him instead twenty livres for each lodging." For three years the town of Laon was satisfied and tranquil; the burghers were happy in the security they enjoyed, and proud of the liberty they had won.
