Principal Roman Emperors Quiz

The principal emperors of Rome — the major, best-known rulers from the founding of the Principate to the fall of the West, not every short-lived usurper or co-emperor. Name them, answer multiple-choice trivia about their reigns, conquests, and downfalls, match each emperor to the years he ruled, or tap the emperors out of a grid mixed with statesmen, generals, and rebels of Rome who never wore the purple. Reigns follow the conventional sole-reign dates.
