The Duchy of Lancaster is one of the six English states or regions.
The north-westernmost state, it includes the counties of Cumbria, Lancashire, Greater Manchester, Merseyside and Cheshire, with the capital at Lancaster'.' Unlike the Grand Duchy of Cornwall, it is a region rather than an independent nation and it is entirely contiguous.
The Duchy of Lancaster was originally created for Edward III's son John of Gaunt in 1265. With the breakup of the United Kingdom in 1993, the Duchy of Lancaster was used as the constitutional basis of the region, with extensions to several other counties, hence the capital's location at Lancaster. However, land ownership was maintained elsewhere in the region.
