69 A.D.: The Year of Four Emperors is a very interesting book on a topic I knew very little about, though I've read books on other periods in Roman history. Professor Morgan's book is strong on analysis as he compares and contrasts the ancient sources, i.e. Tacitus, Plutarch, Dio, Seutonious, Josephus and the so called Common Source. Morgan also begins by mentioning the other books written on this period and what their strengths and weaknesses were.
The historical period in question begins with the reign of Nero and his suicide in 68 A.D. Nero's death marked the end of the Julio-Claudian dynasty and ushered in a brief period of usurpations starting with Galba, followed by Otho, then Vitellius and finally Vespasian who ushered in the Flavian dysnasty that would rule for over 25 years. We get glimpses of these four individuals, how they achieved the highest office in Rome, and what roles their supporters and opponents played, including the legions, various generals and other members of Roman society.
This was a very unsettled time in Rome's history (to say the least), but Morgan doesn't give it the impression of threatening the empire's survival. There are many brutal acts committed including those against some of the usurpers, one emperor's supporters against another would-be emperor's supporters, and Roman citizens in various locations, including Cremona and Rome itself. No one really comes off looking that good throughout this period of instability. I still felt the information was too sketchy on many points, which I guess shouldn't be surprising considering how long ago this was and the limited historical evidence.
Morgan is good in pointing out the strengths and weaknesses of the ancient sources for this period, especially concerning Tacitus. As any student of history mustn't forget, those who write history often have their own agendas or biases, as Morgan discusses. The methods for writing and stylistic approaches were often very important for these early writers as well. The appendices at the end are very helpful. There are a few maps in this book, though I would have liked a few more.
Overall, this is an informative book written by an expert who knows his subject matter. I wish I could comment more intelligently on some of his interpretations, which could be open for debate I feel. This of course has a lot to do with the ancient sources and figuring out whose versions are more accurate. The views on Galba and Otho for example are discussed in one of the appendices to show some of these conflicting opinions. In terms of readability, I had to slow down more often for this book, partly due to my own lack of knowledge of this particular period in Rome's history. A good book.
