United Kingdom

The Union Jack, the flag of the UK

The United Kingdom of Great Britain and Northern Ireland, also called the UK, Britain or GB, is a kingdom in western Europe comprising the Island of Britain and the northern provinces of the Island of Ireland. It is a union of four nations, England, Wales, Scotland and Northern Ireland (also known as Ulster), all under the rule of the British monarch from the capital city of London.

Reformed Christianity finds much of it's origins in the UK. Though technically originating in southern France with John Calvin, today both the largest Reformed denominations, Presbyterianism and Reformed Baptism, were formalised in the UK.
