Wales is one of the four constituent countries of the United Kingdom of Great Britain and Northern Ireland. Wales is closely, but far from completely, integrated politically with England, although it was from around the 16th century until the mid-19th century.

It is located in the south-west of the island of Great Britain and is bordered by England to the east, the Bristol Channel (Môr Hafren) to the south and the Irish Sea (Môr Iwerddon) to the west and north, and also by the estuary of the River Dee (Afon Dyfrdwy) in the north-east.
