„Herodotus considered the Getae "the bravest and the fairest of the Thracians" and the Thracians "the largest people in the world, second only to the Indians". Herodotus thought that "had they one leader only, or could they agree with each other, this people would be invincible and much more powerful than all the others". But the historian of Halicarnassus hastened to add "yet this is not possible and never will be" and he was quite right, too. The Thracians had never been united as one single people. A certain measure of unity was achieved by most of the southern Thracian tribes under the Odrysae kings (in mid-5th century B.C. and early 4th century B.C.) and also by the northern Thracians, namely the Daco-Getae under Burebista when, as foreseen by the great Greek historian f our centuries earlier, they could not be conquered.”
