Yorkshire is a historic county in northern England and the largest in Great Britain. Although Yorkshire is not a current a single unit of civil administration, The name is familiar and well-understood across the United Kingdom and is in common use.
Yorkshire is currently sub-dived into South, West, and North Yorkshire Areas.
The 19th century saw Yorkshire's continued growth, with the population growing and the Industrial Revolution continuing with prominent industries in coal, textile and steel (especially in Sheffield). However, despite the booming industry, living conditions declined in the industrial towns due to overcrowding, this saw bouts of cholera in both 1832 and 1848. Fortunately for the county, advances were made by the end of the century with the introduction of modern sewers and water supplies. Several Yorkshire railway networks were introduced as railways spread across the country to reach remote areas. County councils were created for the three ridings in 1889, but their area of control did not include the large towns, which became county boroughs, and included an increasing large part of the population.
During the Second World War, Yorkshire became an important base for RAF Bomber Command and brought the county into the cutting edge of the war. In the 1970s there were major reforms of local government throughout the United Kingdom. Some of the changes were unpopular, and controversially Yorkshire and its riding's lost status in 1974 as part of the Local Government Act 1972. With much receded borders, the official entity which currently contains most of the area of Yorkshire is the Yorkshire and the Humberside region of England.
