North East England in the Seventies and Eighties
One of the most important political changes of the 1970s was the establishment of the new counties of Cleveland and Tyne and Wear which swallowed up the most populous chunks of Northumberland, Durham and North Yorkshire. Coal mines continued to close in the 1970s and 1980s with the issue coming to a head in the bitter miners’ strike of 1984-85. By the end of the 1980s, there were only six collieries left in the land between Tyne and Tees and only two left in Northumberland.

Confusingly, some parts of ancient Cleveland further to the south like the village called Carlton-in-Cleveland near Stokesley, are not included in the new ‘county’ of Cleveland. To further confuse, a quite separate village called Carlton near Stockton-on-Tees, that was historically in County Durham, now finds itself ‘in Cleveland’. Bureaucrats who created the new county no doubt just liked the name.
