I’m very interested in the Roman conquest of Britain and have spent many hours reading the answers provided by r/Askhistorians members.
I’d like to develop my own knowledge by reading full texts and would like to ask if there is a good starting point?
From documentaries I’ve watched, museum visits and general education, I’d describe my experience level as advanced beginner, if there is such a thing... probably just a beginner haha
I’m particularly interested in the Roman perception of the British tribes they encountered and how exactly these people were assimilated to the Roman way of life.
Thank you
You should start with the best primary sources. First is Caesar's Gallic Wars. If you are an advanced beginner, I highly recommend the Landmark Caesar. It is an excellent translation of not only the Gallic Wars but also Civil War, as well as copious notes and maps and appendices. Even though Britain does not factor into the Gallic Wars until the fourth book (section), you should read from the beginning to get the background. The Britanni were not very different from their Continental Celtic brethren.
I would also recommend the sourcebook by Stanley Ireland: Roman Britain: a Sourcebook (Routledge 2008). This one is very expensive on amazon, but your local library might be able to get it for you. A sourcebook collects primary source evidence for a topic and presents it in an organized manner along with notes and further discussion. The Routledge series is very very good. From there you can launch into other sources (like Suetonius on Claudius, or Tacitus Agricola, etc).
For your interest in particular of British Romanization, I would recommend Tacitus Agricola.
