In ancient Greece, was a region, ill defined, stretching N. of Macedonia to the Danube, and W. of the Euxine (Black Sea); appears never to have been consolidated into one kingdom, but was inhabited by various Thracian tribes akin to the Greeks, but regarded by them as barbarians; since the capture of Constantinople by the Turks the northern portion of Thrace has been annexed to Eastern Roumelia, while the remainder has continued a portion of the Turkish empire.
