In ancient times, the many different societies (usually organized as city-states) of Greek civilization were unified in times of stress or conflict, if not always unanimously. The greatest unifying conflict for the Greeks came from invasions by the Empire of Persia, whose incursions into the center of the Greek world in the 5th century BCE (or BC) were especially significant: it was only by banding together that the Greeks were able to repel the large-scale invasion by land and by sea.
