The Greek Archaic Period (c. 800- 479 BCE) started from what can only be termed uncertainty and ended with the Persians being ejected from Greece for good after the battles of Plataea and Mykale in 479 BCE.
In the Archaic Period, there were vast changes in the Greek language, society, art, architecture, and politics. These changes occurred due to the increasing population of Greece and its increasing amount trade, which in turn led to colonization and a new age of intellectual ideas, the most important of which (at least to the modern Western World) was Democracy. This would then fuel, in a rather circular way, more cultural changes.
