Republics live in fear of tyranny so they create a structure to lower the risk of revolution. In Rome, two consuls were elected for one year terms and had veto control over each other. Other magistrates, such as tribunes, were also elected for a single year. Proconsuls were administrators of foreign territories and as military leaders were not allowed to bring their army onto the Italian peninsula – a rule broken by Caesar when he crossed the Rubicon.
Republics were only marginally more successful than Democracies in the period between antiquity and the modern age. One could cite Switzerland in the middle ages and Florence during the renaissance as examples. Again, innovative political models with equality and freedom were stifled by the medieval monarchical view.
