Is the Romulan Empire a democracy though or a dictatorship?
Debatable. Neral described himself from humble orgins and he rose from a "lowly guard" as he described himself to both Proconsul and Praetor. Which would be Head of Government/State respectively I believe.
A Senate by it's definition implies elections. How democratic they were, especially given the fact the "Romulan traditionalists" seemed to always be in power, is questionable. They definitely have no problems conquering people and subjugating lower castes however.
