Cumbria replaces County Borough of Carlisle
The Windscale fire of 10 October 1957 was the worst nuclear accident in Great Britain's history.Cumbria was created in 1974 from the traditional counties of Cumberland and Westmorland, the Cumberland County Borough of Carlisle, along with the North Lonsdale or Furness part of Lancashire, usually referred to as "Lancashire North of the Sands", (including the county borough of Barrow-in-Furness) and, from the West Riding of Yorkshire, the Sedbergh Rural District. Between 1974 and 2023 it was governed by Cumbria County Council but in 2023 the county council was abolished and replaced by Cumberland and Westmorland and Furness. 
On 2 June 2010, taxi driver Derrick Bird killed 12 people and injured 11 others in a shooting spree that spanned over 24 kilometres (15 mi) along the Cumbrian coastline.Local newspapers The Westmorland Gazette and Cumberland and Westmorland Herald continue to use the name of their historic counties. Other publications, such as local government promotional material, describe the area as "Cumbria", as does the Lake District National Park Authority.
