The Roman Emperor was the ruler of the Roman State during the imperial period (starting at about 27 BC). The Romans had no single term for the office: Latin titles such as imperator (from which English emperor ultimately derives), augustus, caesar and princeps were all associated with it. In practice, the emperor was supreme ruler of Rome and supreme commander of the Roman legions.


There are many very well-documented genealogies connecting the Roman emperors, but the connections to medieval Europe are largely speculative.


The goal of this project is to resolve duplicates, standardize naming conventions, and ensure the quality of the profiles pertaining to the Imperial families of ancient Rome.
