Glamorgan or Glamorganshire (Welsh: Morgannwg) is one of the thirteen historic counties and a former administrative county of Wales. It was originally an early medieval kingdom of varying boundaries known as Glywysing until taken over by the Normans as a lordship. Glamorgan is latterly represented by the three preserved counties of West Glamorgan, Mid Glamorgan and South Glamorgan. The name also survives in that of the county borough of the Vale of Glamorgan.
Although initially a rural and pastoral area of little value, the area that became known as Glamorgan was a conflict point between the Norman Lords and the Welsh princes, with the area being defined by a large concentration of castles. After falling under English rule in the 16th century, Glamorgan became a more stable county, and exploited its natural resources to become an important part of the British Industrial Revolution. Glamorgan was the most populous and industrialised county in Wales and was once called the 'Crucible of the Industrial Revolution' due to the area housing the world centres of three metallurgical industries, and its rich resources of coal.
