Medieval Studies Crusading Warfare
by
John France

Introduction

The Crusades are one of the spectaculars of historical study—a series of events so startling that they demand attention even from writers whose primary interest lies elsewhere. The whole history of western Christendom in the Middle Ages, and indeed beyond, is interwoven with the crusading movement, which became deeply embedded in the piety of medieval people. Partly as a result, the study of the military aspects of the Crusades was long overwhelmed by interest in many other aspects of the subject, especially the nature of the piety that drove people to join these expeditions and to live in the distant East. Thus, much early discussion of military matters was found in general histories of the Crusades or in histories of the warfare of western Europe, and to some extent these remain important. Outline histories of the Crusades are plentiful, but surveys of European warfare are less common, and some old and outdated books are still in use. Writing the military history of the Crusades is no easy task because the sources are voluminous, and many of them contain only passing references to military matters. This, in part, is why no major synthesis has emerged, although in recent years there has been a substantial volume of very specialist writing on the military history of the Crusades.

General Overviews

The nearest works to a general overview are Smail 1995 and Marshall 1992, but they concern only the Crusades to the Middle East. Lewis 1988 sets this conflict into the context of the wider clash between settled and steppe peoples. Ideological aspects are covered in Bachrach 2003, Housley 2002, and Housley 2008, while France 2000 suggests that there was such a thing as a distinctive crusading style of war.

    The Crusades were a form of ideological warfare, and this book seeks to explain the evolution of Christian attitudes to violence.

    This article suggests that the settlers modified their military methods considerably in the face of conditions in the East to produce a distinctive style of war. But if that is the case, did it end with the defeat at Hattin and the collapse of the Kingdom in 1187, after which Jerusalem ceased to be the main participant and became dependent on outside military forces?

    It is often forgotten that crusading did not end in 1291 and covered a much wider area than merely the Middle East. Housley is the preeminent scholar of this later period and here deals comprehensively with military aspects of the subject.

    Only a work of the very highest quality could have such enduring importance. Smail looked at the crusaders in the light of the kind of society from which they came and argued that their fighting qualities arose from the nature of their world and religious beliefs. He paints a striking portrait of a society struggling to survive in a hostile environment and perceives that all kinds of military campaigns were important. A great contribution is to reveal the nature of the fighting march by which the crusaders avoided battle until they could meet it on their own terms. Smail regarded the mounted arm as vitally important for the settlers in the Holy Land but saw the infantry as important but essentially subordinate, and most later writers agree with him. Inevitably, some parts of Smail’s work have been superseded and he omitted some matters altogether.

Histories of Western Warfare

Contamine 1984 presents a general account of Western warfare, though its strength is on the later centuries, which DeVries 1996 and Rogers 2000 discuss in great depth. France 1999 focuses on the age of the Crusades. The essays in Keen 1999 summarize earlier work and are now dated. Nicolle 1995 is very useful, especially for areas outside Europe. Verbruggen 1997 is brilliant on cavalry, but Bennett 1998 provides an alternative view. For technical aspects, see DeVries 1992.

    Verbruggen has relatively little to say about the Crusades in this brilliant book (Dutch original, 1954). He wrote here and elsewhere very perceptively about cavalry warfare, and because of this the balance of the work tends to reinforce the myth of knightly supremacy.

Histories of the Crusades

General histories of the Crusades are legion. Jotischky 2004 is very comprehensive for the Middle East, while Housley 1992 established the study of the later Crusades. Tyerman 2006 is a huge book and very stimulating, while Phillips 2009 emphasizes military matters.

Reference Works

General military companions such as Holmes, et al. 2001 are inevitably thin on the Crusades, but Rogers 2010 has a much closer medieval focus, while Murray 2006 is massive but much concerned with matters other than military. Lock 2006 is particularly useful for historiography. Here again it is important to look at works on both crusading and warfare. There are many encyclopedias of military history, most of which focus on the modern experience. For excellent maps, see Riley-Smith 1990 and Hooper and Bennett 1996.

Bibliographies

Nothing dates like a bibliography, as Mayer 1960 reveals, but DeVries 2002–2006, the International Medieval Bibliography or IMB, and Iter are available in electronic form. France 2001 is useful background for understanding the evolution of the study of medieval military history.

Journals

Most learned journals that cover the Middle Ages publish articles on the Crusades, some of which have military content. The Journal of Medieval History has a strong record in this respect. Crusades, De Re Militari, the Journal of Military History, and The Military Orders are more specialized publications that are likely to publish specifically military material.

Weapons and Technology on Land and Sea

There is a tendency to project our emphasis on military technology into the past, which must be resisted. For arms and armor worldwide, Nicolle 1988 is essential, while France 1997 focuses on understanding the role of technology in the First Crusade. For naval matters, Pryor 1988 is essential, while Prouteau 2008 and Rogers 1992 focus on siege warfare. Kaegi 1964 and Parry and Yapp 1975 are essential for Eastern warfare, while Hyland’s study of the horse (Hyland 1994) is very wide reaching.

Logistics and Crusading Warfare

Logistics was a somewhat neglected aspect of medieval warfare, but even crusading armies had to eat and needed equipment, and this has inspired some attention recently. Leyser 1994 and Nesbitt 1983 focus on the First Crusade, while Pryor 2006 is concerned with the Crusades in general, and Lynn 1993 is much wider but thinner on the medieval experience. Many of the general books on crusading and warfare now pay much attention to issues of supply.

The Individual Crusades to the East

The great Crusades were obviously military expeditions, but it is only comparatively recently that they have attracted specialist studies. Such work has been unevenly distributed, so that many events have been rather neglected, and we are still often dependent on general studies. Part of the fascination of the subject is the clash between the very different styles of war of West and East.

First Crusade

The First Crusade involved very large armies and the whole panoply of contemporary war, with great battles and major sieges. Indeed, the Crusade essentially turned on three attacks on major cities: Nicaea, Antioch, and Jerusalem. The spectacular success of this expedition has attracted disproportionate attention from historians. Riley-Smith 1986 is a general account of the Crusade, but with many observations on the conflict, while France 1994 offers a specifically military overview of the whole campaign. Murray 1992 provides an analysis of a particular contingent, while Riley-Smith 2002 discusses the vexed question of numbers. Prawer 1985 tells us what Jerusalem was like in 1099. Aird 2007, Flori 1999, and Knappen 1928 are biographies of important leaders.

Third Crusade

There are plenty of narratives of the Third Crusade embodied in general histories of the Crusades, but the lack of a specialist study of the Third Crusade is a major gap, especially in view of its plethora of military events. The historiography of this Crusade is dominated by two personalities, Richard the Lionheart and Saladin, both of whom have been widely admired. Ehrenkreutz 1955 and Lyons and Jackson 1979 provide views of Saladin, while Gillingham 1994 is excellent on Richard. Murray 2007 is a welcome new departure of great importance. A number of translations of Latin and Arabic sources have recently appeared and these may prompt further work, which is certainly needed.

The 13th Century and the Later Crusades

The work of C. J. Marshall is very important. Crusading in the 13th century is perceived as dominated by the personality of Saint Louis, brilliantly set in context in Richard 1992. The history of the Latin Kingdom is often seen as dominated by factional struggles, but Jackson 1987 provides an able study of an important issue in this context, and Marshall 1989 and Marshall 1990 are very useful on other military aspects. Housley 2003 provides a fine study of a distinguished medieval crusader who managed to be on the losing side at both Nicopolis and Agincourt, while Halecki 1943 remains the only real study of the Varna episode.

The States of the Latin East, Frankish Greece, and the Byzantine Successor States after 1204

The focus of interest among historians has always tended to be on the Latin Kingdom of Jerusalem, not least because of its prominence in the sources. Recent work has only slightly changed the balance. The states of Frankish Greece and the Cilician Armenian kingdom have been somewhat neglected.

Edessa

Edessa was the first crusader state established in the East, in early 1098, and the first to fall, in 1144. It was always very exposed to hostile attack and has received little attention, apart from Beaumont’s study of its origins (Beaumont 1928), until the excellent work in Amouroux-Mourad 1988.

But Asbridge 1997 and Asbridge 2000 provide the best study of its origins, and France 2001 examines its connections with the wider Norman expansion.

Jerusalem

On the nature of the Kingdom, Ellenblum 1998 is essential, while Edbury 1977 examines evidence bearing upon its military strength, Harari 1997 discusses its light cavalry, and Bennett 2001 looks at the “fighting march” first noted in Smail 1982. Some of the best recent works on military history have focused on the dramatic events that culminated in the destruction of the Kingdom at Hattin in 1187. Barber 1998 brings an important episode to life, while Ehrlich 2007 analyzes a campaign often referred to but little studied. Smail 1982 casts light on the relationship between internal disputes and military events, while Kedar 1992 has produced the best discussion of Hattin.

    This is a radical reassessment of the Latin Kingdom of Jerusalem. Ellenblum suggests that the Latins had put down much deeper roots, colonized the countryside, and established close relations with the native Christians. This sweeps aside the conception of the Kingdom as a transitory structure whose destruction was inevitable. This has clear military implications.

Tripoli

Tripoli was the last established of the principalities and was always closely linked to Jerusalem. The Hospitallers had a strong presence in the county, symbolized by their possession of Crac des Chevaliers. Baldwin 1936 discusses an important count of Tripoli, but Richard 1945 is really the only proper study of the country, and it is now very old.

Armenia

Armenian participation in the Crusades is often forgotten, yet they were vital, as France 1994 (cited under First Crusade) shows, to the success of the First Crusade at Antioch and subsequently played a major role, especially in the history of the principalities of Edessa and of Antioch. Dédéyan 1982 sets this in the context of Armenian history, while Boase 1978 provides a good account of the Cilician kingdom and Edwards 1992 focuses on its fortifications.

The Military Orders

The military orders were a unique product of the Crusade. Their knights were monks who took normal vows but in addition were sworn to defend the holy places and fight the infidel. The Temple and the Hospital originated in the Latin Kingdom and by 1130 had excited so much admiration that they became major landholders all over Europe. Very quickly new orders arose, especially in Spain. It is a curious fact that most studies of the orders focus on them as institutions, and relatively few have a real military focus. This is largely because the sources that have survived are mainly documents about landholdings. Barber 1994 is the study of the Temple, while Forey 1992 and Nicholson 1993 look at other orders. Bennett 1989 is an excellent military study, while Schein 1989 attempts an assessment of the military value of the Templars in the 13th century. Urban 2003 provides a very readable account of the Teutonic Order, while Ekdahl 1982 analyzes one of the most important battles of the later Middle Ages.

Eastern Warfare

Islamic warfare against the Latins was largely conducted by the Turks and associated peoples who came with them into the Middle East after the 11th century. They were essentially steppe soldiers, and this style of light cavalry warfare was dominant. Kaegi 1964 and Bowlus 1996 explore this style of war, while the articles in Parry and Yapp 1975 are very important. Hillenbrand 2000 provides by far the best account of the Muslim reaction to the Crusade. Lev 1991 provides vital studies of the Fatimids, Ayalon 1954 examines the Mamluk army, and Amitai-Preiss 1995 studies a conflict between two steppe peoples.

Fortifications in the East at the Time of the Crusades

When modern historical studies began in the 19th century, scholars were deeply impressed by the numerous ruins of stone castles, many of which had been built on a truly massive scale. This provoked a controversy that continues to the present day about whether and to what extent the crusaders copied Eastern models, Byzantine or Muslim, and thereby influenced castle development in the West. The famous T. E. Lawrence wrote his undergraduate dissertation on this very subject. Modern debate has been based on studies of crusader fortifications such as Deschamps 1934–1973, but more recently, serious studies of Eastern fortifications (such as, Faucherre, et al. 2004 and, Kennedy 2006) have developed, providing a different perspective. Pringle 1986 and Pringle 1997 have been vital in understanding the evolution of crusader castles, and Kennedy 1994 remains the best introduction to the subject. However, the most innovative work is Ellenblum 2007 that, although limited to the Latin Kingdom, combines archaeology and historical study.

    This builds on Ellenblum’s earlier work on settlement and demonstrates how firmly rooted the crusader polity was. The work establishes the various phases of castle building and identifies three periods of building, in the third of which, 1167–1187, there was a remarkable development with the emergence of concentric fortifications. Ellenblum also suggests that these structures were influenced by continuous cultural interchange between the settlers and their neighbors.

Crusading in the West

The work of Riley-Smith and others has established that the Crusades were a much wider phenomenon than merely as expeditions to the Middle East. As a result, there has been new interest, some of which, noted here, has a military aspect.

Spain

Spain was the scene of a long conflict between Christianity and Islam that lasted until the end of the 15th century and even then continued into a struggle for control of the Mediterranean and North Africa. For an outline of the Spanish wars, see Lomax 1978. Fletcher 1987 takes a revisionist view of when they became “holy.” Lourie’s study of the organization of Spanish society (Lourie 1966) was a radical departure, which others, including Powers 1988, have followed.

The Baltic

A strong impetus to the study of the Baltic Crusades is the work of Henry of Livonia, which provides a vivid and startling picture of the brutality of these wars, while the prominence of the Teutonic Order and the survival of many of its great castles have also pushed it to the fore. Christiansen 1997 is the best introduction, while Nicholson 2005 provides an excellent historiographical overview. The essays by specialists in Murray 2001 are very weighty; Urban 1975 provides a lively military history of the Teutonic Order.

Western Europe

There is as yet no comprehensive survey of crusading in western Europe with a military emphasis, and the wars of the papacy and Hohenstaufen in particular need attention. Marvin 2008 is excellent on the rather short part of the Albigensian Crusade he chose to study, while Housley 1982 has looked at the political Crusades of the 13th century, and Heymann 1955 provides a study of a great commander.

Victims and Making Peace

The victims of war have long been neglected, and this was certainly true of the Crusades until very recently. Making peace is a closely related subject since it often involved prisoners and decisions over their fates. The long duration of the wars in Spain led to the rise of institutions that coped with their consequences, and these are studied in Brodman 1985, while Friedman 2002 shows that such institutions did not develop in the Latin East. Edgington 2006 and Mitchell 2001 discuss medical treatment. France 2008 is concerned with the problems of surrender in the Latin East, while Gillingham 2009 takes a broad view of the treatment of prisoners in Europe.
