paragraph_text: Roman Republic
  
  Following the overthrow of the Roman monarchy, the Romans established an oligarchic Roman Republic which divided supreme executive power (Latin: imperium) between two consuls, both elected each year and each holding a veto over the other's actions.
  
  The historical duumviri were not rulers but magistrates, performing various judicial, religious, or public functions.
