THE philosophical tradition of what we call the Western world had its origins in ancient Greece, its jurisprudential tradition in classical Rome. Christianity, the religion of the West, was nursed towards its future spiritual world status in the shelter of Roman imperial domination. Yet the political map of Europe, the heartland of Western civilization, bears little relation to that of the classical Hellenistic and Roman world. Its outlines were shaped not in classical times, but in the middle ages, largely in the course of warfare. That warfare, brutal, chaotic, and at times seemingly universal, is historically important not only for its significance in defining the boundaries and regions of the European future. Fighting in the medieval period, in the course of regional defence against incursions of non-Christian peoples with no background or connection with the former Roman world, and in the course of wars of expansion into territories occupied by other peoples, both Christian and non-Christian, and their absorption, played a vital role in the preservation for the future West of its cultural inheritance from antiquity. It also furthered the development of technologies that the antique world had never known.
Because the notion of sovereign governments with an exclusive right to war-making was in the early middle ages effectively absent and only developed slowly during their course, medieval wars came in all shapes and sizes. To Honoré Bouvet, writing on war in the later fourteenth century, the spectrum seemed so wide that he placed at the one extreme its cosmic level—‘I ask in what place war was first found, and I disclose to you it was in Heaven, when our Lord God drove out the wicked angels’—and at the other the confrontation of two individuals in judicial duel by wager of battle. In between, he and his master John of Legnano placed a whole series of levels of human wars, graded according to the authority required to licence them and the circumstances which would render participation in them legitimate. For the historian, it is easy to think of alternative approaches to categorization to this that Bouvet offered to his contemporaries: indeed the problem is that there are almost too many possibilities to choose from.
The middle ages witnessed great defensive wars, or series of wars, to resist invasions, by Vikings and Magyars for instance in the ninth and tenth centuries, or, later, against the Ottoman Turks in Eastern Europe. There were wars of expansion, the Norman conquests of England and Southern Italy, for example, and the German conquests of former Slav territories east of the Elbe. There were also, of course, the crusades. Under that head must be reckoned not only the crusades to Palestine, but the wars for the reconquest of Spain from the Moors and for the attempted conquest of once Byzantine lands in Greece, the Balkans, and Asia Minor. Crusades, indeed, offer a good illustration of the difficulties of tidy categorization. Because the popes, in the course of their long struggle with the emperors for universal authority in Christendom, came often to give the status of crusader (with its formal privileges and indulgences) to those who would serve them against their imperial rivals (as also to those prepared to fight other excommunicates, heretics, or schismatics within the Christian homeland), crusading war can blend easily into the history of the major internal confrontations of Europe, which did so much to shape its future political map.
In looking at these confrontations, the kind of approach to categorization adopted by Bouvet, with its emphasis on the authority required to make war lawful and on the legitimacy of participation, does become useful. Looking at it in his way, one can place at one extreme what I have called the great confrontations, wars waged on the authority of popes, kings, and princes. Notable among these were the struggles between popes and emperors of the period 1077–1122 (the Wars of Investiture) and of the Hohenstaufen period (between 1164 and 1250): the series of wars (which grew out of them) that we call the War of the Sicilian Vespers, and their subsequent ramifications (1282–1302, and beyond): the great Hundred Years War of England and France (1337–1453). At the other end of the scale stand endless petty confrontations, often amounting to no more than family feuds between aggressive local lords or castellans, but potentially not much less devastating than great wars for the welfare of local people. In between there were wars between protagonists at every level of domination, between rival lords at comital, ducal, or princely level in competition for land and inheritances, and between rival cities; and between protagonists at different levels of dominance, of leagues of barons against kings (as in England in King John’s time and in the time of Simon de Montfort, and later in the Wars of the Roses), of leagues of cities against their overlords (as of the Lombard League against the Emperor Frederick I), and endless individual baronial rebellions against overlords who they claimed had oppressed them or had infringed their rights. The resort to violence was a ready one in the middle ages, at every level of authority.
The difficulty with this sort of classification is that it can be very difficult to keep the categories apart. In medieval political conditions, greater struggles and lesser rivalries very easily blended into one another, though without, in most cases, one fully absorbingthe other. This was a consequence of underlying conditions and the limitations of even the most effective and authoritative of medieval power structures. Between the time of Charlemagne and the later middle ages, virtually no royal, princely, or papal government had the resources in terms of money, manpower, and supply to sustain on its own continuous, large-scale hostilities over an extended period. The solution to the problem was obvious, to find allies whose interests might induce them to join in whatever cause was at stake at their own expense and for their own advantage. Such a struggle as the Wars of Investiture between the popes and the German Salian Emperors Henry IV and Henry V had an almost infinite capacity to draw other parties and their quarrels into its orbit; Saxon and princely rebels against Salian kingship, Norman adventurers in South Italy seeking superior sanction for their conquests, Patarene anti-clericals at odds in Milan with episcopal authority. The later, Hohenstaufen chapter of the papal-imperial rivalry illustrates the same point in a different but comparable way. The party labels Guelf and Ghibelline which loom so large in the story of the wars of Italy in the thirteenth and fourteenth centuries originally denoted theoretically the allies and supporters of the church and the pope (Guelfs) and of the emperor (Ghibellines). In fact from the start they were collective labels for the rival lords, rival city governments, and rival family factions which the two great protagonists succeeded in enlisting to the aid of their respective causes because they were at each other’s throats anyway. Long after the main struggle had been decided against the Empire in the later thirteenth century, Guelfs and Ghibellines continued to league together and to fight one another under the same old labels. Wars tended constantly to spread outwards from their epicentres as well as inward towards them. This made it very hard to delimit and control their scale, impact, and duration, let alone to define their ‘level’ in terms of categorization.
War is thus central to the narrative political story of the middle ages. It is also central to their cultural history. Indeed, their martial secular culture may arguably be claimed to be, along with their Christian ideology, one of the two chief defining features of their civilization. The middle ages are often recalled as the Age of Faith: they are often also recalled as the Age of Chivalry, or as the Feudal Age.
In a famous triad, the thirteenth-century author of the Chanson des Saisnes (the ‘Song of the Saxon Wars’) declared that there were three ‘matters’ of which every man should know something: the matter of Britain, the matter of France, and the matter of Rome the Great. The matter of Britain meant the stories of King Arthur, and of the adventures of his knights in battles and tournaments. The matter of France meant the stories of Charlemagne and his paladins, and their part in wars against Saracens and in the internecine struggles of the Carolingian nobility. The matter of Rome the Great meant the history of Greece and Rome, of the wars of Alexander and Caesar and, most emphatically, the Trojan war. These three matters did indeed become the most staple themes of secular aristocratic literary creation from the twelfth century on. Lays and romances based on them inevitably focused around warfare, around accounts of wars, battles, tournaments, and single combats (in the medieval versions of the classical stories, their antique heroes appear as knights in contemporary armour, with fine war horses and heraldic blazon on their shields). Literature thus became a powerful influence in reinforcing and fostering for the secular aristocracy a martial value system whose bellicosity should not be underestimated. Along with courage, loyalty, and liberality, it set a very high price on physical strength, good horsemanship, and dexterity with weapons, and on impetuous ferocity in combat. This value system was what we call the code of chivalry, and these military virtues and skills were the defining features of its cult of honour.
Alongside this literary triad of the author of the Chanson des Saisnes may be set another triad, the traditional medieval division of Christian society into three orders or estates. These were, first, the clergy, whose business was with prayer and with pastoralministration to society’s spiritual needs; secondly, the warriors, whose business it was with their swords to uphold justice, protect the weak, and to defend church and homeland; and, third, the labourers, by whose toil the land was tilled and whose work provided for the material needs both of themselves and of the two other, more socially elevated estates. First clearly articulated by King Alfred in his translation of Boethius, this conception of society in terms of three functionally related estates achieved over time such wide currency as to seem almost a truism: ‘you know that there be three estates of men’, the poet Gower wrote in the fourteenth century. It was of course at best an ideal formulation which never accurately reflected the facts of life and of social gradation. The specific justification that it offered for the warrior’s calling as a Christian vocation with a vital social function was however profoundly influential. It underpinned the secular aristocracy’s self-image as a hereditary martial estate and gave a firm ideological grounding to its claims to status and privilege.
It is natural and appropriate to associate this threefold vision of society and its view of the warrior’s place in it, with what historians call feudalism. True, the military model of feudalism, which has been widely used in order to explain relations in the upper echelons of medieval society in terms of a hierarchic structure of contracts, based on grants of land by superior lords to lesser men in return for military service, is now looked at askance by many scholars. Nonetheless it remains true that in the relations between a great (or even not so great) lord and his subordinates, whether as his bodyguards or household servants or tenants or kinsmen, or as in later medieval England as retainers, military service throughout the middle ages was consistently presented as a specially prized and dignified form of service. Whether we call them feudal or not, notions of lordship and clientage to which military service was central permeated medieval conceptions of social relationships at the aristocratic, landowning level, and to a considerable degree, at other levels as well.
An acceptance, in some measure at least, of the aristocrat’s right of resort to military violence was the natural obverse to this perception of obligations. That is what lies behind the tone of moral confidence with which nobles tenaciously resisted (for instance in France in the time of Louis IX) attempts to curb their customary seigneurial right to pursue their own claims by private wars on their own motion (in what is sometimes called ‘feudal’ war), notwithstanding the adverse social consequences which could so obviously stem from the privilege. The dignity associated with the warrior’s functional status could serve as a reminder of his ethical and social duties: it could also promote more wars.
Both feudalism and chivalry—or something rather like them—were features of medieval civilization in its longue durée. There are variations in their specific modes of manifestation over time and from region to region, but they or something like them are always there. One reason for this was the very slow rate of technological advance in the art of warfare during the middle ages. There were developments, and important ones at that: the extended use of stone in fortification (especially in castle building): new techniques for manufacturing better armour for both fighting men and horses: new sophistications in the design of crossbows and longbows. Yet there was nothing that altered radically and rapidly what John Keegan has called ‘the face of battle’—until the coming of gunpowder artillery and of new techniques in ship design and navigation at the end of the medieval period. The cultural perception of the warrior aristocrat and of the code of behaviour and social standing appropriate to the military calling did not shift very markedly or very fast, largely because the conditions of the martial context of battle, to which a warrior was expected to respond, shifted only very slowly.
A second reason for the longevity of the chivalrous ideal and of feudal factors (or comparable ones) is more complex, and requires more careful consideration. In the twelfth century there was a real breakthrough, not in the art of war but in bureaucracy and the techniques of literate administration. The exponential growth in governmental records of all sorts from that point on bears impressive witness to its impact. This breakthrough opened new vistas of possibility for central governmental supervision down to local level (provided the ‘centre’ was not too remote geographically). Static administrative headquarters, such as Paris and Westminster, acquired a new importance. Princely rulers, with the aid of their professional clerical servants, gained a new capacity to supervise legal processes and local conflicts of interest, and above all to tax (and to borrow, offering anticipated revenue as collateral) on a greatly extended scale. This should have had a very important effect on the capacity of such rulers to plan, organize, and direct large-scale military operations, and indeed it did. Yet in the context of warfare that effect was in many respects secondary, especially once the scene changed from the planning table to the operational field. The impact on traditional martial attitudes and behaviour in belligerent conditions was in consequence less sharp than one might expect it to have been, and only began to be fully apparent after a considerable time lapse, arguably not until well into the fifteenth century.
One positive and more immediate effect of the new administrative potential of government was that rulers such as the kings of France and of England in the thirteenth, fourteenth, and fifteenth centuries found themselves able to gather large armies from a wider recruiting base than had their immediate predecessors, and to entertain higher and better defined territorial and dynastic ambitions for the outcome of successful war. They also found it possible, through literate publicity, organized preaching, and other brands of stage management, to reach out for a more conscious and patriotic collective response to their war-making from their subjects, and thus to justify more imperative fiscal demands. These were among the most important factors which, in the later middle ages, were visibly accelerating the definition on the map of the future power structures of Europe.
Greatly improved and professionalized though administrative services became, they nonetheless still had their limits. War is and always has been a highly cost-intensive business. For a very long time—in effect till the end of the middle ages—the new fiscal and monetary resources into which rulers were now able to tap, while adequate to pay for military service during actual campaigns, were not sufficient to enable them to maintain standing, permanent forces on any really significant scale, let alone to train them. They could of course employ mercenaries, whose captains came ready equipped with standing forces and technical military skill. Demand here helped to create supply: but mercenaries did not come cheap, and there were other problems, notably what to do with them when a campaign was concluded. In order to raise armies late medieval rulers had in consequence still to rely primarily, as their predecessors had done, on their greater subjects, who had the wealth to equip themselves and their followers, an established social charisma, and a nexus of connections among kinsmen, vassals, tenants, and servants which made them ideal recruiting agents. Untrained in the formal sense, these lords and magnates, along with their followers, and like their ancestors before them, were men who had been brought up physically to martial exercises, to horsemanship, hunting, and jousting, and civilly to a sense of social obligation with very strong martial resonances. In the field, the service of such men and their followers was a very adequate substitute for a professional army. What assured their availability, however, even now that they were usually paid or promised pay for a campaign’s duration, was not that they had ‘taken the king’s shilling’, but their traditional sense of their standing in society and its functional obligations. In these conditions, it was positively in a ruler’s interest to cultivate rather than to castigate their traditional outlook, to present himself as the companion and generous patron of his martial, aristocratic subjects, to heed their sensibilities and maintain their privileges. Otherwise he risked losing control of his war machine. Small wonder then that it was only very slowly and partially that the new administrative capacities of government began to have a significant effect on feudal and chivalrous manners of living, and on the accompanying mental attitudes that had been formed and forged in earlier times.
Thus for a long time it seemed necessary, from a ruler’s point of view, to accept the price that was attached to this condition of things, alternatives to which were in any case perceived only dimly, if at all. That price was the ongoing risk that the martial energies and resources of a ruler’s greater subjects continued to be all too easily channelled into causes other than his, into crusades, into confrontations with fellow magnates, into private territorial adventures—and rebellion. That is a chief reason why the middle ages, to their close, were so dominated by wars at so many levels.
But time passes. Lessons of experience sank in, and perceptions of new potentialities sharpened. At the end of the middle ages rulers were getting richer and were learning more about how to flex their governmental and administrative muscle. One symptom of this was the more strenuous and better directed effort made to control the right of their great noblemen to make war other than by their leave: another (partly as a means to that first objective) was that we find them (or some of them, the Kings of France and Spain in particular) beginning to establish large-scale military forces on a standing, paid basis. Chronologically, this opening of the story of professional, national standing armies coincides with the time in which technological advances in gunnery and navigation were beginning to have significant impact—and when a good many historians recognize the passing of the age of chivalry. Around 1500, shifts in conditions which had been from a military point of view defining features of the medieval period were beginning to accelerate. That is why this book ends there.
The fact that warfare and the warrior ethos were so central to the secular history of the middle ages, political, social, and cultural, has shaped the planning of this book. It is divided into two parts. The aim of the contributors to Part I has been to bring out, stage by stage and age by age, something of the societal experience of war, and of the impact of its demands on human resources and human endurance. Contributors of the first four chapters of Part II have sought to trace thematically the most important developments in the art of warfare: in fortification and siegecraft, in the role and equipment of the armoured cavalryman, in the employment of mercenary forces. The penultimate chapter examines the gradual emergence of an articulate approach to the non-combatant; and the final one considers some of the factors that were changing the face of battle at the close of the middle ages.
Limitations of space have meant that we have not been able to give separate attention to as many themes and topics as we would have wished. Ideally, this book would include individual chapters on, for instance, medieval opinions about the just war, on feudal relations and changing perceptions of their military significance, on chivalry and the tournament, on rights to loot and ransoms, and on taxation for war purposes. We have done our best to incorporate some treatment of these and other matters into the framework of various chapters, but inevitably there has been some skimping on topics that we recognize as important.
One omission imposed by lack of space is the absence of any in-depth treatment of the Byzantine face of medieval warfare. To have attempted to do justice to it would have meant placing in context a whole series of great wars, in the Balkans, Asia Minor, Syria, and beyond, which have no direct connection with the warfare discussed in this volume. It would have meant, too, outlining a structure of military organization radically different from that of the contemporary Western European world—a structure moreover that under force of circumstances was altered over time almost beyond recognition. So the telling of that story will have to wait for the publication of the forthcoming illustrated history of Byzantium from Oxford.
Nevertheless one very broad and general point seems worth making here. The Byzantine story is in many ways the reverse of that which this volume seeks to trace. At the beginning of the period here covered the Byzantine Empire was a major territorial power, served by a sophisticated bureaucracy and with an effective system of tax collection. Its army was a powerful military machine, with an established provincial command structure, readily mobilizable for large-scale campaigns. In his Precepts, the great tenth-century soldier Emperor Nicephorus Phocas was able to outline for the army principles of recruitment and training, to detail the arms and equipment needed by respectively light and heavy cavalry, infantry, javeliners, and archers, and to discuss with assurance tactics and strategy. Yet the eleventh century would see the erosion of imperial authority through the growing independence of the great, semi-feudal landowners of the provinces, and the loss of control of the Anatolian hinterland as a result of Seljuk incursions, and, at its end, a new threat developing from the West. In the twelfth century, relations with the crusading West deteriorated steadily, and in 1204 the army of the Fourth Crusade stormed and seized Constantinople. Though the Byzantines did succeed in recovering their capital city in 1261, theirs was thereafter an empire in name only. They failed to regain Greece, and their last strongholds in Asia Minor were soon lost to the Ottomans. At the end there was still an administrative bureaucracy in Constantinople but there was no longer a recruiting base for an army. Well before the time that the emergent Western monarchies began to show signs of an ability to curb effectively aristocratic martial independence, Byzantium had lost control of its provinces to regional great nobles, and in the Balkans to warlike invaders, Slav, Bulgar, and Serb. In the end all went down before the Turk, whom the Westerners succeeded ultimately in halting, a little within the line of the Danube.
To both these contrasted histories, Western and Eastern, Latin and Greek, warfare and its outcomes provide an essential connecting theme. It is now time to turn to look in more detail at the Western side of the story, with which this book is principally concerned, beginning in the time of Charlemagne, whose eighth-century Frankish empire resembled that of contemporary Byzantium perhaps only in that both were essentially military powers.
