In order to accurately appreciate the causes of the almost perennial struggles between the sovereigns of Flanders and their subjects throughout the Middle Ages, it is important to know something of the men, and of their position in the body politic who formed the backbone of the people’s resistance; of the men from whose primitive institutions were gradually evolved the complicated municipal machinery by which all the great cities of Flanders were eventually governed, and in defence of which almost all the struggles in question were originally undertaken. These men were the Flemings or Karls of the seaboard, Saxons of pure blood, distinct in race, though not in speech, from the inhabitants of the towns, for in the veins of the townsman there often flowed a strain of Celtic blood, and at Bruges especially, where, as we know, at an early date there was settled a colony of foreign merchants, the population must soon have become one of mixed race.
The Karls then formed a class apart, a vast middle class of free landholders, distinct alike from the Court nobility—the comrades of the Count, his bodyguard, the great feudal lords who knew no trade but war—from the vilains or serfs who were their retainers; and from the inhabitants of the towns. But the Karl was not only a farmer, he was sometimes also a fisherman, often a merchant, and always, and above all things, a soldier. If it had been otherwise, he could never have preserved either his own personal freedom or the freedom of the soil he tilled. To him toil was no disgrace. The greatest of their chiefs, even those among them in whose veins ran noble blood, were not ashamed to dig.
Herred Krangrok, who dwelt along with his wife Ethel, a niece of the Bishop of Térouane, in the impregnable Castle of Salvesse in the midst of the marshy forest land, which in those days stretched away beyond Furnes, was a typical Karl of high degree. This man seems to have been a brewer by trade, and they gave him the surname Krangrok from a habit he had of throwing his cloak back over his shoulder when he was driving his own plough.
The home of the Karls was a long strip of territory stretching along the coast from the great Abbey of Muenickereede to the marshes of Wasconingawala in the county of Guines—a strip of territory of unequal width, of which the northern boundary would now be difficult to trace, but which certainly included within its borders the townships of Ardres, of Alveringhem and Furnes—the vast forest of Thorout, and all that district which was later on submitted to the jurisdiction of the Liberty of Bruges.
This land was divided up into a number of districts called circles or guilds, which the inhabitants themselves administered by means of their own elected chiefs, who were at the same time their magistrates and their legislators.
The ties which bound them to the sovereign were of the loosest nature, amounting to little more than this—personal service for the protection of the Fatherland, and the payment of a voluntary tribute which they themselves assessed.
Certainly up to the end of the tenth century, and perhaps for a century later, the Karls were still a fierce, wild race, much given to hereditary feuds and private warfare, still infected with Pagan superstitions, and still occasionally practising Pagan rites.
The vast majority of them were poor, but a certain number, especially after the triumph of Robert the Frisian, succeeded in amassing wealth, and of these not a few filled high positions alike in Church and State.
Under the sovereignty of the early Flemish Counts the Karls had little to complain of, and though doubtless the feudal tendencies of their rulers were fostered by the rapprochement with Normandy under Baldwin le Barbu and Baldwin of Lille, the Karls were still so independent of their princes, that whilst Baldwin, for a consideration, was helping William in his projects against England, the Karls were straining every nerve in behalf of their Saxon kinsmen on the other side of the water, and it was not till the regency of Richilde of Hainault, the widow of Baldwin the Good, that any systematic attempt was made to bring them under subjection.
In the neighbouring States of Guines and Normandy, Northern freedom and Northern notions of liberty had long ago given place to a feudal régime of the sternest type, under which the freehold farmer of olden days had rapidly sunk into the vilain. The untimely death of Baldwin the Good, in 1070, afforded the Flemish barons, as they thought, a fitting opportunity for reducing the Karls of Flanders to a similar condition. Arnulph, the heir to the throne, was a youth of fifteen years, and Richilde of Hainault, the Countess Dowager, had assumed the reins of government and taken for her chief councillor Albéric de Coucy, a man who, on account of his tyrannical tendencies, had experienced the wrath of Baldwin of Lille. The first measure of her reign showed the spirit by which she was animated—the imposition of a tax, an inaudita et indebita tributa, as Lambert of Ardres describes it, the proceeds of which were intended to defray the cost of maintaining town ramparts. Since these had hitherto been kept in repair by means of forced labour, and the Böelfart was only to be levied on the Karls of the seaboard, they naturally regarded the measure in question as a direct attack on their liberty.
