If you're interested in terrorism (worldwide) from the 19th century through the Great Depression or the secret diplomatic and police campaign that was conducted against it, you're not going to want to miss this AMA. Dr. Jensen is one of the leading historians of political violence in this era and spent about 10 years composing his latest work. He has published several articles (and one book) in public security/terrorism in Italy during the 19th century, as well as several manuals for instruction of history in the modern world.

I'll be with Dr. Jensen to show him the format, and, as always, the AMA will be posted about 1-2 hours early so that our Europeans can have a shot at getting their questions in while there's still time in the day. We are excited to welcome him to /r/AskHistorians, and we sincerely hope that you will join us for the AMA.
