We know how the Roman republic was governed, but we don't know for certain how the Etruscans governed. Etruscan civilisation decayed quite early on, during the period of the Late Roman Republic. Even the Etruscan language disappeared. Hardly any writing in Etruscan has survived and the few extant inscriptions pertain mostly to religion. Because we don't have enough knowledge of the way the Etruscans ruled, we cannot compare this with the Roman Republic. Moreover, Etruria (the Land of the Etruscans) did not have a unified state. It was a collection of independent city states, like Greece (before the formation of the kingdom of Macedon and the kingdom of Epirus), Latium (Land of the Latins) before Rome took over most of it, and other areas of Italy. Each Etruscan city-state had its own political arrangements. We know that they were monarchies ruled by a lukum (lucumo in Latin). All we know about Etruscan city states comes from what the Romans wrote about them, and this pertained mostly to the wars the Romans fought against them. For example, we know that in Volsinii power was taken over by freedmen and that they introduced laws which restricted the privileges of the aristocracy. The aristocracy asked Rome for help. The Romans besieged the city, destroyed it and resettled its inhabitants to a new town, Volsinii Nova (New Volsinii).
