The Byzantines are a Southern European civilization in Age of Empires II (Middle Eastern before the Definitive Edition). Although classified as a defensive civilization in-game, they are a versatile civilization in practice, relying on a wide variety of units of all categories for both offense and defense strategies.
The capital Constantinople was the center of a trading network extending across nearly all of Eurasia and North Africa, in particular as the primary western terminus of the Silk Road; the rest of Europe would not match the Byzantines' economic strength until late in the Middle Ages. This is reflected by the Byzantines having access to all economic (Lumber Camp, Mill, and Mining Camp) upgrades.
The Byzantines inherited advanced construction techniques from the Greeks and Romans. To reflect this, all their buildings become tougher with every Age for free, and do not need to research Masonry and Architecture. They also deflected near constant invasions from more numerous but less advanced armies from Europe and Asia, and the double walls of Constantinople had a reputation for impenetrability for a millennium before they were overran by the Turks. This is shown in their access to all fortifications, their cheaper counter units (Camel Riders, Spearmen, and Skirmishers), and their access to Town Watch for free. Their defensive theme is further supported by their Monkshealing faster, which is also a reference to the Byzantines retaining and building upon the Greek medical knowledge that was lost and had to be rediscovered elsewhere.
Finally, the Byzantines' defensive prowress extended to the waters with their continuation of Roman naval techniques and new inventions of their own like Greek fire, a type of napalm that could ignite even on water. This is referenced by the Byzantines being the only civilization with access to all naval upgrades and technologies (along with the Spanish), their Fire Ships attacking faster, and their Castle Age unique technology Greek Fire, which grants Fire Ships +1 range.
The Byzantine units speak Latin, which they share with the Italians, and the Briton Monks and Kings. Historically, the Byzantine Empire ditched Latin as an administrative language in the 7th century, in favor of Medieval Greek, their most commonly spoken language. The Latin language itself evolved into the slightly different Medieval Latin. There are some obvious mistakes in the unit voice lines, such as asking "I command?" when other civilizations use "Your command?", or using "Hunted" instead of "Hunter" or "To hunt". Byzantine units also differ in that they talk in the first person, while most civilizations use the third person or the infinitive.

The Byzantines took their name from Byzantium, an ancient city on the Bosphorus, the strategic waterway linking the Black Sea to the Aegean Sea. The Roman Emperor Constantine had renamed this city Constantinople in the fourth century and made it a sister capital of his empire. This eastern partition of the Roman Empire outlived its western counterpart by a thousand years, defending Europe against invasions from the east by Persians, Arabs, and Turks. The Byzantines persevered because Constantinople was well defended by walls and the city could be supplied by sea. At their zenith in the sixth century, the Byzantines covered much of the territories of the original Roman Empire, lacking only the Iberian Peninsula (modern Spain and Portugal), Gaul (modern France), and Britain. The Byzantines also held Syria, Egypt, and Palestine, but by the middle of the seventh century they had lost them to the Arabs. From then on their empire consisted mainly of the Balkans and modern Turkey.
The first great Byzantine emperor was Justinian I (482 to 565). His ambition was to restore the old Roman Empire and he nearly succeeded. His instrument was the greatest general of the age, Belisarius, who crisscrossed the empire defeating Persians to the East, Vandals in North Africa, Ostrogoths in Italy, and Bulgars and Slavs in the Balkans. In addition to military campaigns, Justinian laid the foundation for the future by establishing a strong legal and administrative system and by defending the Christian Church.
The Byzantine economy was the richest in Europe for many centuries because Constantinople was ideally sited on trade routes between Asia, Europe, the Black Sea, and the Aegean Sea. It was an important destination point for the Silk Road from China. The nomisma, the principal Byzantine gold coin, was the standard for money throughout the Mediterranean for 800 years. Constantinople’s strategic position eventually attracted the envy and animosity of the Italian city-states.
A key strength of the Byzantine Empire was its generally superior army that drew on the best elements of the Roman, Greek, Gothic, and Middle Eastern experience in war. The core of the army was a shock force of heavy cavalry supported by both light infantry (archers) and heavy infantry (armored swordsmen). The army was organized into units and drilled in tactics and maneuvers. Officers received an education in military history and theory. Although outnumbered usually by masses of untrained warriors, it prevailed thanks to intelligent tactics and good discipline. The army was backed by a network of spies and secret agents that provided information about enemy plans and could be used to bribe or otherwise deflect aggressors.
The Byzantine navy kept the sea-lanes open for trade and kept supply lines free so the city could not be starved into submission when besieged. In the eighth century, a land and sea attack by Arabs was defeated largely by a secret weapon, Greek fire. This chemical weapon, its composition now unknown, was a sort of liquid napalm that could be sprayed from a hose. The Arab navy was devastated at sea by Greek fire.
In the seventh and eighth centuries, the Arabs overran Egypt, the Middle East, North Africa, and Spain, removing these areas permanently from Byzantine control. A Turkish victory at Manzikert in 1071 led to the devastation of Asia Minor, the empire’s most important source of grain, cattle, horses, and soldiers. In 1204 Crusaders led by the Doge of Venice used treachery to sack and occupy Constantinople.
In the fourteenth century, the Turks invaded Europe, capturing Adrianople and bypassing Constantinople. They settled the Balkans in large numbers and defeated a large crusader army at Nicopolis in 1396. In May 1453, Turkish sultan Mehmet II captured a weakly defended Constantinople with the aid of heavy cannon. The fall of the city brought the Byzantine Empire to an end.
Historically, the Byzantines referred to their empire as the "Roman Empire" or the "Kingdom of the Romans" (Greek: Βασιλεία τῶν Ῥωμαίων), "Romania" (Greek: Ῥωμανία meaning "Land of the Romans"), "Graecia" (Greek: Γραικία meaning "Land of the Greeks") and "Rhōmais" (Greek: Ῥωμαΐς). They likewise referred to themselves as "Romans", "Greeks" and/or "Hellenes" (Romaioi, Graikoi and Ellines in Greek respectively) since they were the political continuation of the Roman Empire in the east, as well as the direct heirs and guardians of Hellenic civilization. They were also known as "Greeks" in Western Europe due to the Greek language they spoke. Both the terms "Eastern Roman Empire" and "Byzantines" are modern historiographical terms that refer to the empire and its inhabitants respectively and were developed years after the fall of the empire's capital, Constantinople, in 1453 due to the invasions of the Ottoman Turks.
After changing to the Mediterranean architecture set in the Definitive Edition, the Byzantines are the only civilization with European architecture that can train Camel Riders.
The Byzantines and the Teutons are the only "defensive" civilizations in The Age Of Kings. Their "defensive" point aren't changed in the later expansions.
The Byzantines are one of the four civilzations that have access to Paladins, but not Bloodlines (the other being Burgundians, Celts and Franks, although the later have a civilization bonus that gives their cavalry units +20% HP), and one of the two civilizations that have access to Camel Riders without Bloodlines (the other being the Ethiopians).
The Byzantines are a very effective civilization for new players and beginners, mostly due to having a very open tech tree in all stages of the game for various areas and strategies.
Also, they are one of only two civilizations that have both Paladins and Arbalesters. However, they lack both Bloodlines and Blast Furnace for Paladins, making them less powerful compared with the other civilization, the Magyars.
Despite being the only civilization with Paladin, Arbalester and Siege Rams, which are essential in team games, the Byzantines are the worst one in this case. Their winning rate in team games is the lowest, probably because their main strength is trash units, which is not as useful as in 1vs1 games. They have no significant advantage to their archers, mediocre Stable units (no Bloodlines and Blast Furnace), which leads to them being an unwise choice to be in pocket. They also lack an economy advantage to boom.
Conversely, the Byzantines have a higher winrate in lower ELO and a lower winrate in higher ranks. This is mainly because their additional HP on buildings makes it easy for newer players to play defensively and boom (combined with their diverse tech tree), while their noticeable weaknesses (such as their focus on "counter" trash units and lack of early-game economic bonus) makes their defensive playstyle more punishing in higher ranks by playing a civilization with a stronger economic bonus with a strong late-game.
