The Stoic school of Western moral philosophy was founded by Zeno of Citium (334-262 B.C.). He was the founder and first head, from 300-262, of the Stoic school in Athens. He was followed by Cleanthes (331-232) who was head of the school from 262 to 232, and Chrysippus (280-206), who led from 232-206. "Although we possess no complete works by any of these thinkers, with the possible exception of Cleanthes' relatively brief Hymn to Zeus, we possess a lot of information about their views by way of summaries, quotations, and paraphrases (often critical or hostile) in later writers. About Zeno of Tarsus, fourth head of the Stoic school, from 206 through early second century, we know very little." - http://groups.yahoo.com/group/stoics/message/5703?viscount=100 Jan Garrett, in the stoics yahoogroup

Andrew Erskine's research claimed "that the early Stoa was politically active and had a vigorous egalitarian thrust, i.e., it was characterized by a principled opposition to hierarchy." In particular, a single command hierarchy.

This is ironic considering that the best known stoic was Marcus Aurelius, who was Roman Emperor in the 2nd century AD.
