Macrinus was Roman emperor from April 217 to June 218 CE. It is a story that has been told countless times before - an emperor is assassinated leaving no heir or successor. On April 8, 217 CE Roman Emperor Caracalla was murdered, supposedly on the orders of the man who would eventually become his successor, Macrinus. This new emperor, during his 14-month reign, would have two major distinctions - he would never step foot in Rome as emperor, and he would be the first never to have served in the Senate.
