The lower part of the Greek peninsula, known as Laconia, was settled by the Dorian branch of the Greek family, a practical, forceful, but a wholly unimaginative people. Sparta was their most important city. To the north were the Ionic Greeks, a many-sided and a highly imaginative people. Athens was their chief city. In the settlement of Laconia the Spartans imposed themselves as an army of occupation on the original inhabitants, whom they compelled to pay tribute to them, and established a military monarchy in southern Greece. The people of Attica, on the other hand, absorbed into their own body the few earlier settlers of the Attic plain. They also established a monarchy, but, being a people more capable of progress, this later evolved into a democracy. The people of Attica were in consequence a somewhat mixed race, which possibly in part accounts for their greater intellectual ability and versatility. [4] It accounts, though, only in part. Climate, beautiful surroundings, and contact with the outside world probably also contributed something, but the real basis underneath was the very superior quality of the people of Attica. In some way, just how we do not know, these people came to be endowed with a superior genius and the rather unusual ability to make those progressive changes in living and government which enabled them to make the most of their surroundings and opportunities, and to advance while others stood still. Far more than other Greeks, the people of Attica were imaginative, original, versatile, adaptable, progressive, endowed with rare mental ability, keenly sensitive to beauty in nature and art, and possessed of a wonderful sense of proportion and a capacity for moderation in all things. Only on such an assumption can we account for their marvelous achievements in art, philosophy, literature, and science at this very early period in the development of the civilization of the world. CLASSES IN THE POPULATION. Greece, as was the ancient world in general, was built politically on the dominant power of a ruling class. In consequence, all of course could not become citizens of the State, even after a democracy had been evolved. Citizenship came with birth and proper education, and, before 509 B.C., foreigners were seldom admitted to privileges in the State. Only a male citizen might hold office, protect himself in the courts, own land, or attend the public assemblies. Only a citizen, too, could participate in the religious festivals and rites, for religion was an affair of the ruling families of the State. In consequence, family, religion, and citizenship were all bound up together, and education and training were chiefly for citizenship and religious (moral) ends.
