Yorkshire is a former county in England. In general speaking, its name is still used.
It covers a large area of the Pennines and its East coast borders the North Sea. The River Humber separates Yorkshire from Lincolnshire & Southern England, while the River Tees and Pennines mountain range separates Yorkshire from County Durham, Lancashire and the North of England.
Yorkshire was historically split up into three parts known as the East, North, and West Ridings during and after the 7th century Norse settlment, while the county town York was in the middle. In the local government reorganization of England in 1974 the counties of West Yorkshire, North Yorkshire, South Yorkshire were established instead. Humberside included the former East Riding and Cleveland included part of the former North Riding.
