It was created in the early 4th century under the reforms of Diocletian and it has been suggested that its capital may have been at Lincoln (based on a proposed amendment to the corrupt Verona List). Its boundaries are uncertain but probably consisted of the southern Pennines, stretching west to the Irish Sea and may have extended far enough south to encompass the territory of the Iceni. The capital of Britannia Secunda at York indicates that Flavia's territory did not extend much further north of Lincoln.
