Fortifications


Building city walls was of fundamental concern to the imperial administration, as is evident from Justinian’s plan to build walls around many cities and fortify areas of major strategic significance.

Together with the political and economic decline that gradually set in from the late 4th century, natural disasters and epidemics led to significant changes in the form of cities.

Some were abandoned and others shrunk in size and population, while new cities were established at virtually inaccessible sites, their main aim being to provide security to inhabitants. The fundamental objective of fortifications was to ward off attacks by creating barriers, which were set up one after the other so as to guarantee defence. The number and height of walls, the shape and form of towers, the number of gates and their guard systems were all determined by the lie of the land, developments in warfare and prevailing economic and building potential.

As a rule, walls consisted of towers with two or more levels, from which the defenders would attack the enemy, and of high curtain walls thick enough to withstand attacks. Cities on the plains had another lower outer wall punctuated by towers, in front of which was a moat that could be flooded to check the enemy. At the highest point of the settlement lay the acropolis or citadel. With its own wall for defensive autonomy, this was the last refuge for defenders, and housed the seat of church authority and military command. From as early as Justinian times, an intermediary wall divided the city in two, thus providing a further line of defence. The gates opened at sunrise and closed at sunset. They were few in number, since they were established at the most vulnerable points in the fortifications.

As an outstanding set of defences, the walls of Constantinople set the standard for fortifications around Byzantine cities. Indicative of their quality is the fact that the walls withstood siege by the Ottomans for over a thousand years.

Lastly, fortresses and towers were fortifications which, like city-castles, adopted the rationale of successive lines of defence. Their aim was to control strategic positions and passes and defend wider geographical areas. In addition, they provided storage for agricultural produce, accommodation for local rulers and shelter for the population in times of danger.

Justinian I: Byzantine Emperor (527-565), nephew and successor of Justin I. One of his first acts was to reform the tax system and recode Theodosius’ laws. He was personally involved in religious conflicts and convened the 5th Ecumenical Council (553). Justinian considered himself primarily an orthodox emperor and took harsh measures against the remaining pagans. Many of his political and fiscal actions provoked strong reactions on the part of the senate and the factions and led to the Nika Riots. Justinian instigated numerous building projects, erecting approximately 30 churches in Constantinople, including the famous church of Agia Sophia. Regarding foreign policy, he successfully confronted the Persians and the Vandals in the East and focused on the recovery of the West. This he temporarily achieved, but at such cost that the Empire was left exhausted; the barbarians in the Balkans plundered the Greek peninsula as far as the Isthmus and barbarian tribes settled at the borders. His military operations exhausted Byzantium financially and militarily and had no real effect, as Italy and other areas he conquered were soon lost again. After his death, the weakened empire had to face new attacks, culminating in the Arab conquests, which negated the majority of Justinian’s conquests beyond the borders.
The city: Constantinople, the capital city of the Byzantine Empire, was built on the site of the ancient Greek colony of Byzantium, on the triangular peninsula formed by the Golden Horn, the Bosporus and the Sea of Marmara. This was an excellent location that controlled trade routes linking the Aegean to the Black Sea. Emperor Constantine founded Constantinople in 330 AD as a city to rival Rome in splendour, wealth and power. The city grew fast, leading to problems of space and facilities, so Theodosius I extended it to the west by building new strong walls that protected Constantinople until the end of the Byzantine Empire. The city was laid out after Rome. A main road, the Mese Odos, linked the palace to the Golden Gate. On this road was the Forum, a circular plaza with a statue of Constantine mounted on a column, surrounded by public buildings. Theodosius I and Arcadius later built more forums decorated with their own statues. Following the Nika riots in the 6th century, Justinian adorned Constantinople with magnificent edifices, palaces, baths and public buildings. This time also saw the construction of Agia Sophia (the Holy Wisdom), the church which served as the seat of the Ecumenical Patriarchate throughout the Byzantine period. During the 7th and 8th centuries Constantinople faced major problems that threw it into disarray: attacks by the Avars (a siege in 674) and Arabs (attacks in 674 and 717-718); natural disasters (a powerful, destructive earthquake in 740); and epidemics (plague in 747). Limited building activity resumed in the 8th and 9th century, mainly concentrated on strengthening the city's fortifications. With the recovery of the Byzantine Empire from the 9th to the 11th century, Constantinople became the most populated city in Christendom; the majority of inhabitants were Greek-speaking, but many other ethnic groups lived alongside them, such as Jews, Armenians, Russians, Italians merchants, Arabs and mercenaries from Western Europe and Scandinavia. Many public, private and church-owned buildings were erected at the time, with an emphasis on establishing charitable institutions such as hospitals, nursing homes, orphanages and schools. Higher education flourished, thanks to the care of the state and the emergence of important scholars. This renaissance lasted until the mid-11th century, when economic problems due to poor management set in, compounded by the adverse outcome of imperial operations beyond the borders. The Crusaders left Constantinople entirely unscathed when first passing through, but in the Fourth Crusade of 1204 the Franks conquered and ransacked the city, slaughtering those inhabitants they did not take prisoner or drive out. In 1261 the city was retaken by Michael VIII Palaeologus, who rebuilt most of the monuments and the walls but proved unable to restore the city to its former splendour and glory. Enfeebled as it was, the empire was incapable of checking the advance of the Ottomans, and in 1453 Constantinople finally fell into their hands. The fall signalled the end of the empire. Nevertheless, the Byzantine intellectual tradition remained significant, as many scholars settled in the Venetian dominions of Crete and the Peloponnese, as well as in European countries, conveying Greek learning to the West.
