The Eastern Roman Empire, a continuation of the Roman Empire in its eastern provinces during Late Antiquity and the Middle Ages, centered its power in Constantinople. This polity maintained Roman laws, traditions, and infrastructure while developing a distinct culture influenced by Greek language, Orthodox Christianity, and interactions with Eastern civilizations. Its political structure featured a centralized administration under an emperor considered divinely appointed. An example of its lasting influence is the codification of Roman law under Justinian, which shaped legal systems for centuries afterward.
Understanding the civilization centered in Constantinople is crucial for comprehending the development of Eastern Europe, the spread of Orthodox Christianity, and the preservation of classical knowledge. Its interactions with neighboring powers, including those in the Islamic world and Western Europe, shaped geopolitical landscapes. Its art, architecture, and literature influenced cultural developments across a wide geographical area. Furthermore, its economic activities, including trade routes connecting East and West, played a significant role in global exchange.
