The romans were a mix of both. Dangerous, and unprincipled...geared toward keeping the masses happy, and the elites in charge...unless they were murdered...even the Caesars.What conflict exactly would that be?
A Republic is small limited government, where the people are served rather than regulated, represented rather that ruled.
A Democracy is a large government, with entitlements to the people and where the people and businesses are regulated.
As Plato warned in his Republic that as a rule, tyranny arises from democracy.
We need to get away from the Democracy that we have become and get back to the Republic, that we are suppose to be.
The conflict is - Republic-small government and Democracy - large government.
Plato was Greek
Romans were a Autocratic Republic without a constitution, for the people.
Greece moved from their Republic to a Democracy and look at where they are at now.
