England, also called The Kingdom of England, or, on occasion, The Kingdom of England and Wales, was a medieval kingdom situated on the British Isles, sharing a border with Scotland and a maritime border with Ireland and France. For most of its existence, England was an economic and political powerhouse, its sphere of influence stretching across the British Isles and North Sea, and often south to France and the Holy Roman Empire. Due to its powerful location, England was widely considered one of the most powerful nations in Europe, even during its traumatic Era of uncertainty.
