Legendary - War of the Gods
The Thracian people, while considered barbarian and rural by their refined and urbanized Greek neighbors, have developed advanced forms of music, poetry, industry, and artistic crafts. Aligning themselves in kingdoms and tribes, they never achieved any form of national unity beyond short, dynastic rules of strong cults of personality.
Thracian civilization is not urban and the largest Thracian cities are in fact large villages. The Thracians were typically not city-builders, though they have built a few large poli. While nominally aligned with other Greek city-states, their militia and tribesmen are no match for professional armies of larger empires. That doesn’t mean they won’t fight to the last, however.
