Archaic Greece was the period in Greek history lasting from the eighth century BC to the second Persian invasion of Greece in 480 BC, following the Greek Dark Ages and succeeded by the Classical period. The period began with a massive increase in the Greek population and a series of significant changes which rendered the Greek world at the end of the eighth century as entirely unrecognisable as compared to its beginning. According to Anthony Snodgrass, the Archaic period in ancient Greece was bounded by two revolutions in the Greek world. It began with a "structural revolution" which "drew the political map of the Greek world" and established the poleis, the distinctively Greek city-states, and ended with the intellectual revolution of the Classical period.
The Archaic period saw developments in Greek politics, economics, international relations, warfare, and culture. It laid the groundwork for the Classical period, both politically and culturally. It was in the Archaic period that the Greek alphabet developed, that the earliest surviving Greek literature was composed, that monumental sculpture and red-figure pottery began in Greece, and that the hoplite became the core of Greek armies. In Athens, the earliest institutions of the democracy were implemented under Solon, and the reforms of Cleisthenes at the end of the Archaic period brought in Athenian democracy as it was during the Classical period. In Sparta, many of the institutions credited to the reforms of Lycurgus were introduced during the period, the region of Messenia was brought under Spartan control, helotage was introduced, and the Peloponnesian League was founded, making Sparta the dominant power in the region.
The word "archaic" derives from the Greek word archaios, which means "old". It refers to the period in ancient Greek history before the classical. The period is generally considered to have lasted from the beginning of the eighth century BC until the beginning of the fifth century BC, with the foundation of the Olympic Games in 776 BC and the Second Persian invasion of Greece in 480 BC forming notional start and end dates. The Archaic period was long considered to have been less important and historically interesting than the classical period, and was primarily studied as a precursor to it. More recently, however, Archaic Greece has come to be studied for its own achievements. With this reassessment of the significance of the Archaic period, some scholars have objected to the term "archaic", due to its connotations in English of being primitive and outdated. No term which has been suggested to replace it has gained widespread currency, however, and the term is still in use.
