Britannia Secunda
Britannia Secunda was one of the provinces of
Roman Britain in existence by c. AD 312 and probably created as part of the administrative reforms of the Roman Emperor
Diocletian by after the defeat of the usurper
Allectus by
Constantius Chlorus in AD 296.
The governors of Britannia Secunda were of equestrian rank although few are known by name. Their capital was at
York.
The province is named in the
Verona List and probably encompassed all of what is now northern
England and possibly north
Wales. In
369 a new province of
Valentia was created, probably from a portion of Britannia Secunda.
