The legend ‘300’ originated during the mass wars between Greece and Persia. Persian warriors were brutal, and more and more lands were conquered barbarously. Greece now and then had to constantly defend their cities and lands.
The king of Persia threw a huge horde of his best warriors into the land of Greece. This would seem to be the end. But it was not for nothing that the warriors of Sparta were famous for their courage and military skill. The best of the best gathered 300 Spartans to stop the advance in a strategic place, in a narrow crevice. Thanks to this legendary battle, the course of the whole war was broken.
