Quite quick all the best grain-growing areas were occupied and the estates separated unfair. The most became nobly property and beside lack of space resulted unhappiness. The beginning of the Archaic Period is characterized by emigration. So the first Greek colonization were founded in the western world. One of the first cities was Cumae in the bay of Naples, founded by Cyme and Chalcis.

Soon some other new colonized establishments came after it. Chalcis founded a new Naxos near Taormina on Sicily, and Rhegium in Calabria, nowadays Reggio and Messina. Corinth founded Syracuse and Kerkyra, nowadays Corfu. The Achaeans of the north of the Peloponnese occupied the land in Sybaris, Kroton and Metapont in south Italy. Also Sparta founded Taranto in south Italy and the inhabitants of Rhodes and Crete settled down on the south coast of Sicilian. Around 630 BC raised further colonies of the Ionian from Phokaia (Minor Asia), in the very west. Nice, Antibes, Monaco and Marseilles go back to the Ionian settlement. South Italy became something like a part of Greece.

Through the colonization, newly established cities took over the cults, customs and sometimes even the constitution of their mother city. The mother city mostly provided the leader and the ships for the expedition. The leader often became later the ruler or even the King of the city (Poleis). It was possible to established new colonies everywhere, where was no resistance, and the people could concentrate to built up their city and the social system, without defending their territory against enemies. With this you can explain that the begin of colonization in the north of the Aegean, because of stronger enemies, started later.

Probably Mileto introduced the colonization in the North. It founded Istros, Olbia, Apollonia, Odessos and Tomis. It is said that they founded also more than 70 cities on the coast of the black Sea. The inhabitants of Megara joined them and it raised Heraclea, Kallatis and Chersonesus. Also around 630 BC came up the Dorian settlement in Cyrene, Lybia.
