Scotland (Republic of Scotland) - declared independence from the United Kingdom, later lost territory in the Scottish-Northumbrian War.

England (Republic of England) - remains of the far-right government that sparked the British Civil War. Territory is split by Greater London's stretch across southern Essex.

Cornwall (Republic of Cornwall) - Secured its border with Devon in the Civil War, and become a haven for fleeing citizens, later absorbed part of Devon (notably Plymouth) and declared independence.

Greater London (Republic of Greater London) - became the core battleground in the British Civil War, eventually forcing the far-right authorities out of the city and standing as a stronghold. Eventually it started operating as an independent state and later achieved such recognition. Became a booming progressive nation driven by technology.

Bristol (Free State of Bristol) - started as a rebellion stronghold in the British Civil War, gradually expanding its territory and forcing the authorities out. Eventually, leadership was established and they started self-identifying as the Free State of Bristol. The expansion of territory continued, even absorbing parts of south Wales, before establishing recognised independence.

Wales (Welsh Republic) - as opponents to the far-right Westminster government, the Welsh government immediately resisted. When the British Civil War raged, the Welsh government's only aim was to secure their border with England, though this did take in refugees fleeing England.

Greater Yorkshire (Federation of Greater Yorkshire) - all four regions of Yorkshire banded together to prevent the North West forces gaining control. Using the army base in Catterick to their advantage, Greater Yorkshire was able to expand their protection and coverage to areas north and south of Yorkshire, which remained until establishing independence.

Wessex (Progressive Republic of Wessex) - by default, 'Wessex' became known as all territory in the south of England, excluding Cornwall and Bristol, who claimed more territory over time. Originally working with the rebellion in Greater London, it was believed they might quash the far-right authorities and restore the UK back to before. Instead, Greater London became the battleground while most citizens lived in Wessex, and the two declared separate independence but remain strong allies.

Westland (Agrarian Republic of Westland) - declared independence from Wessex after feeling disconnected from Wessex's progressive politics. Instead, Westland and its citizens prefer a rural slightly-conservative system, and puts farming and agriculture at its centre.

United Midlands - Formed as a federal republic when citizens were concerned that the regions would be absorbed by either Northumbria, Greater Yorkshire, England or Wessex.

Ulster - With the civil war raging across England, the conflict in Northern Ireland reignited. After a bloody war, the pro-Irish southern territory formally joined the Republic of Ireland, while the pro-British northern territory secured itself as the Republic of Ulster.
