hi! if you don't get the detail you're looking for here, these posts include source references

• When did the Roman Chariot "factions" appear?

• Nika Riots - Sources and Modern Interpretations?

meanwhile, these don't answer your questions, but may be of tangential interest to you or other readers

• The Blues and the Greens

• Who were the "Blues" and the "Greens" in the Byzantine empire?

• what was the difference between the Greens and the Blues leading up to and during the Nika Riots?

• I've been reading a lot about chariot racing in the Byzantine Empire and the connected Fan groups/Hooligan Gangs. These groups had huge influence and sometimes caused riots where thousands of people died. Can anyone explain them in more detail?
