De Imperatoribus Romanis: An Online Encyclopedia of Roman Rulers and Their Families

DIR is an on-line encyclopedia on the rulers of the Roman empire from Augustus (27 BC-AD 14) to Constantine XI Palaeologus (1449-1453). The encyclopedia consists of (1) an index of all the emperors who ruled during the empire's 1500 years, (2) a growing number of biographical essays on the individual emperors, (3) family trees ("stemmata") of important imperial dynasties, (4) an index of significant battles in the empire's history, (5) a growing number of capsule descriptions and maps of these battles, and (6) maps of the empire at different times. Wherever possible, these materials are cross-referenced by live links.
 
These contents are supplemented by an ancient and medieval atlas, a link to a virtual catalog of Roman coins, and other recommended links to related sites. The contents of DIR have been prepared by scholars but are meant to be accessible to non-specialists as well. They have been peer- reviewed for quality and accuracy before publication on this site.
