The Roman army is one of the most famous fighting forces in history. Through its power and prowess, a once obscure Italian city forged an empire that encircled the Mediterranean and covered half of Europe. The physical remains of its presence can be traced from the mountainous borders of Scotland to the arid deserts of Egypt, but its legacy is far greater and more enduring, as Rome's influence continues to shape the political, legal, and cultural landscape of Europe to this very day.

While the Roman army is rightly famed as an institution, the image of the individual legionary is also an iconic one. The uniformed, disciplined soldier of the late Republic and early Empire is one of the first things many people imagine when they think of Rome. They are the ultimate image of the ancient soldier, their arms and armor instantly recognizable. Their abilities, not only as warriors but also as engineers and administrators, have made them role models for other soldiers through the centuries. In the same vein, their commanders are still celebrated and studied, and generals the world over have tried to emulate the likes of Julius Caesar.

Constantine may well have set the stage for the ultimate collapse of the Roman Empire as it had existed up until that point. It was Constantine who first decided that Rome, exposed and vulnerable near the gathering masses of barbarians moving into Germania and Gaul, was a strategically unsafe base for the Empire, and thus expanded the city of New Rome on the Dardanelles straits, creating what eventually became Constantinople. By moving the political, administrative and military capital of the Empire from Rome to the East, as well as the Imperial court with all its attendant followers, Constantine laid the groundwork for the eventual schism which saw the two parts of the Roman Empire become two entirely separate entities, go their own way, and eventually collapse piecemeal under repeated waves of invasion.

As a result, the Byzantine Empire was the heir to two great cultures that cradled and nurtured European civilization: Greece and Rome. Constantinople, now called Istanbul, became a center of power, culture, trade, and technology poised on the edges of Europe and Asia, and its influence was felt not only throughout Europe but the Middle East, Africa, Central Asia, and the Far East. Coins dating from the reign of Emperor Justinian I (r.527-565) have been found in southern India, and Chinese records show that the “Fulin,” as the Chinese named the Byzantines, were received at court as early as 643 CE. For a thousand years, the Byzantine Empire protected Europe from the Islamic Arab Empire, allowing it to pursue its own destiny. Finally, Byzantium was a polyglot society in which a multitude of ethnic groups lived under the emperor prizing peace above war, an inspiration surely for the modern age when divisive nationalism threatens to dominate society once more.
Despite all this, the Byzantine Empire is often treated as a medieval oddity, an absolute state stunted by a myopic religion, a corrupt, labyrinthine bureaucracy, and an inability to adapt to change. In truth, none of these judgments bear any serious scrutiny - Byzantium was a strong, organized, highly effective and adaptable civilization for most of its long history. It owed its success in no small part to its military, which, in contrast to the feudal armies of Western Europe and the tribally based forces of the Middle East, operated with a high level of discipline, strategic prowess, efficiency, and organization.
