After Agricola, the following emperors conducted major military operations in Britain: Hadrian, Antoninus Pius, Septimius Severus, and Constantius I.
[citation needed] The discovery in the 1970s, and continuing unveiling of, the Vindolanda Tablets offer a unique glimpse into the everyday lives of auxiliary soldiers stationed in northern England in the period 85–122, just before the construction of Hadrian's Wall.
These documents (752 of which have been published to date), consist of letters and memoranda written on wooden tablets to and from the auxiliary soldiers garrisoning the fort of Vindolanda (Chesterholm).
[5] In general, the Tablets show the Roman Empire was far more bureaucratised than previously thought, with likely millions of written documents generated every year by the army alone.
They also established beyond reasonable doubt that Roman soldiers (at least auxiliaries) wore underpants (subligaria)[7] and used a disparaging nickname for their British hosts: Brittunculi.
