The walls of Antioch are the only visible memento of the ancient city. Continuously repaired and reconfigured, they encompass at least eight different phases. How these defenses document the transformation of the city through the ages is the core issue.

Siege warfare followed most of the practice established before, but a larger use of guns, the improvement of gunpowder and sometimes orders to fight to the last stand led to an escalation in violence. This was enhanced too by the growing involvement of civilians, especially in Spain, which gave a more exacerbated dimension to the fights

This chapter spans the history of European siege warfare across the long eighteenth century, from the age of Louis XIV to the Napoleonic Wars. It lays out the key thematic groundwork and siege case studies explored in later chapters. The first half outlines the nature of ‘the siege’ as the classic form of old-regime positional warfare – its operational forms, temporal and spatial dimensions, and rituals and customary laws of war – and charts the relative historic decline of breach assaults and siege related massacres of garrisons and civilians in the eighteenth century. The second half shifts to the Revolutionary-Napoleonic era. It identifies the continuing importance of siege operations beyond their earlier high point in European military affairs; the regional and chronological shifts in sieges across the Napoleonic Wars; the nature of British siege operations in Continental Europe and the colonial sphere (India and South America); and ends with an overview of British and French sieges in the Peninsular War – the epicentre of Napoleonic siege warfare and of the storming and sack of besieged towns.

Chapter 7, “The Defence of Constantinople,” examines the factors at play in the defense of Constantinople – geography, fortifications, land and naval forces, adequate supply of water and provisions, and, most importantly in the eyes of its inhabitants, the miraculous tutelary powers resident in the God-guarded city.

City streets, fortification walls, and gates were key elements of Athenian topography that structured urban space throughout the history of the city, directing circulation both under urgent circumstances and in everyday life. With their continuous repairs and modifications, they remained a fixed point and the backbone of the urban fabric.

The ages of humankind are designated by the material with which they made tools and weapons: stone, bronze, and iron. Remnants of these tools and weapons, found in archaeological excavations, are often the earliest evidence of existence in a place, especially before humans were able to express (and depict) themselves in words or art. Artistic depictions would follow, and then written ones, but both several thousands of years later. A wood, stone, or metal club, a stone or metal spearhead or arrowhead, a metal dagger or sword – and this appears to have been the progression – all could be used for hunting, likely their main function in pre-agricultural societies.

The years around 1200 ce mark a significant turning point in the history of warfare in India, due to the decisive campaigns waged in northern India by the Ghurids of Afghanistan and the concomitant introduction of new forms of military culture from the eastern Islamic world. While limited parts of India’s periphery had been under Islamic rule long before this time, it was only under the Ghurids that Islamic control was established in the core region along the Ganga and Yamuna rivers (the “Ganga-Yamuna Doab”). A series of decisive battles was carried out here between 1192 and 1206, under the direction of Quṭb al-Dīn Aybeg, a Turkish slave commander (ghulām) in the service of the Ghurid sultan Mu‘izz al-Dīn Muḥammad bin Sām. Even after Mu‘izz al-Dīn’s death in 1206, Aybeg remained in India controlling the newly acquired Ghurid territories from his base in Lahore in the Punjab.

The defining feature of Western warfare in this period was knighthood. This was not because horseback warfare was in any way new in the Frankish lands, or even because the technology of the equipment and use of cavalry had changed in any radical sense, though it is generally assumed that the stirrup appeared as a feature of cavalry equipment at some time in the ninth or tenth century, thus allowing the saddle to become a more effective fighting platform. But the stirrup did not by any means create the knight. What the knight represented was a new social phenomenon which grew progressively more important as generations passed and read new meanings into the status and potential of knighthood.

In popular perceptions, the later Middle Ages loom large as the apogee of medieval chivalry, epitomised by the foundation of chivalric orders, such as the Order of the Garter, by instructional texts such as the Livre de Chevalerie of Geoffroi de Charny, and by the chronicles of Jean Froissart (c.1337–c.1405), written

The Crusades have always been a focus of historical attention. William of Tyre (c.1130–86) wrote a great history of the crusades in Latin which was so well received that in the early thirteenth century it was translated into French and extended in many versions to cover the period after 1186. The French version was so popular that the Renaissance scholar, Francesco Pipino, unaware of the original, translated it back into Latin, while Caxton produced an English version in the fifteenth century.1 Many of the earlier crusader chronicles, notably Robert the Monk’s account of the First Crusade, were also very popular in the Middle Ages and were edited very early in the age of print, notably in the great collection by Jacques Bongars in 1611.2 In modern times the crusades have always been a contentious subject, as President George Bush discovered when he referred to a ‘crusade against terrorism’ shortly after 9/11.

The Americas constitute one of the most topographically diverse and environmentally heterogeneous regions of the world, and each of these dimensions, and a host of social, economic, political, and cultural variables, necessarily serve to define the nature of war and society in the American hemisphere. In the two centuries anticipating Columbian contact with the New World in 1492, the Americas were largely dominated by the rise and fall of hundreds of kingdoms and warring polities, and the emergence of two powerful, albeit militaristically distinctive, imperial traditions – one Mesoamerican, the other Peruvian. Each evolved from a pattern of military statecraft and conquest interaction that coalesced in the highlands of each region in the period extending from 1300 to 1500 ce. While the Andean highlands of Peru and Bolivia were the crucibles of a centuries-old tradition of empire building, questions regarding the extent to which Mesoamerican empires fully and completely consolidated their gains as hegemonic imperial formations remain.

From the late fourth century onwards, Christendom was assailed by a succession of invaders. The first wave consisted of Germanic tribes – Visigoths, Ostrogoths, and Vandals – and their irruptions brought down the West Roman Empire. During the sixth century, Slavonic groups emerged in the territory north of the Danube that the Germanic tribes had evacuated and began incursions into the South-East European lands of the Byzantine empire. In the late ninth century, the old Roman province of Pannonia together with the Hungarian Great Plain was occupied by the Magyars, a Finno-Ugrian group, originally from Siberia, that had over the preceding centuries made its home on the western steppes. The Magyar settlement destroyed several nascent Slavonic principalities and was accompanied by extensive raids into the Balkans and Western Europe.

Divided political landscapes such as that of the Classic Maya are, with a relentless regularity, filled with competing ambitions and deeply felt animosities. The periodic rupture of hidden fault-lines exposes where the pressure points and conflicting interests lay at any one time. War is one of the most complex of all social phenomena. While violent conduct may seem chaotic and emotionally driven it is, in the end, grounded in a calculation between the risks and rewards sufficient to motivate a life-threatening activity. Nonetheless, wherever we find it, warfare is shaped by powerful cultural understandings that dictate its form and meaning and these comprise an equal part with any pragmatic understanding.
