The land now known as Bulgaria attracted human settlement as early as the Bronze Age. Almost from the first, however, existing civilizations were challenged by powerful neighbors.

Pre-Bulgarian Civilizations

The first known civilization to dominate the territory of present-day Bulgaria was that of the Thracians, an Indo-European group. Although politically fragmented, Thracian society is considered to have been comparable to that of Greece in the arts and economics; these achievements reached a peak in the sixth century B.C. Because of political disunity, however, Thrace then was successively occupied and divided by the Greeks, the Persians, the Macedonians, and the Romans. After the decline of the Macedonian Empire of Alexander the Great, a new Thracian kingdom emerged in the third century B.C. Occupied by the Romans, it remained a kingdom within the Roman Empire until the emperor Vespasian incorporated it as a district in the first century A.D. Roman domination brought orderly administration and the establishment of Serditsa (on the site of modern Sofia) as a major trading center in the Balkans. In the fourth century A.D., when the Roman Empire split between Rome and Constantinople, Thrace became part of the Eastern, or Byzantine, Empire. Christianity was introduced to the region at this time. Both the Latin culture of Rome and the Greek culture of Constantinople remained strong influences on ensuing civilizations.
