Originating as a popular form of entertainment in 19th-century Europe and later as a sideshow exhibition in North American traveling carnivals and vaudeville halls, professional wrestling grew into a standalone genre of entertainment with many diverse variations in cultures around the globe, and is now considered a multimillion-dollar entertainment industry. While it has greatly declined in Europe, in North America it has experienced several different periods of prominent cultural popularity during its century and a half of existence. The advent of television gave professional wrestling a new outlet, and wrestling (along with boxing) was instrumental in making pay-per-view a viable method of content delivery.

In modern times, a process of devolution in the United Kingdom has decentralised power once again. Since the 1997 referendums in Scotland and Wales and the Good Friday Agreement in Northern Ireland, three of the four constituent countries of the UK now have some level of autonomy. Government has been devolved to the Scottish Parliament, the National Assembly for Wales and the Northern Ireland Assembly. England does not have its own parliament and English affairs continue to be decided by the Westminster Parliament. In 1998 a set of eight unelected Regional assemblies, or chambers, was created to support the English Regional Development Agencies, but these were abolished between 2008 and 2010.
