Final answer:
The counties listed are all in England, which is a part of the United Kingdom alongside Scotland, Wales, and Northern Ireland. The UK operates as a constitutional monarchy with a parliamentary system. Southern England is an affluent region with a diverse economy and historic landmarks.
Step-by-step explanation:
The counties of Cornwall, Devon, Kent, Northumberland, Essex, Suffolk, Norfolk, Surrey, and West and East Sussex are all located in the country of England. England, along with Scotland, Wales, and Northern Ireland, forms the United Kingdom (UK) of Great Britain. England's history features a series of independent kingdoms such as Wessex, Mercia, and others, along with significant events like King Alfred's defeat of the Danes and William the Conqueror's victory at the Battle of Hastings. Southern England, where many of these counties are situated, is the most affluent region of Great Britain and includes the seat of government and primate city of London, as well as renowned universities like Oxford and Cambridge.
The UK government operates as a constitutional monarchy with a monarch who serves mainly as a figurehead, while the parliament, comprising the House of Commons and the House of Lords, exercises legislative powers. This region of England is known for its economic diversity and has transitioned from industrial to postindustrial activities. Tourism has become a significant economic activity especially in coastal counties like Cornwall and Devon.
