The case of archaic Greek tyranny

Greek archaic tyranny can be studied as a case of mobility of a form or practice of power (as well as of a style or metaphor of power) under both a geographical and a diachronic aspect. This political model moves from Asia to Greece, then from one polis to another, and evolves from the mid VIIth century BC to the late VIth. Moreover, from another point of view, tyranny can be analyzed as a factor of social mobility and complexity growth, especially in terms of land appropriation by dependent or impoverished peasants as well as of demographic and economic encrease of urban populations.
