The United Kingdom was a nation in Europe. In the British Isles, the nation created a superpower that came to odds with France often. One of the last times it came to odds with France was during the First Great War, in which an Anglo-German alliance defeated France. However, Germany's newfound power led to them engaging in the First Phony War with Germany , until full-fledged war broke out between them as the Second Great War began. Britain won the war, but they were weakened to the point that they were forced to reform their empire into the equal-representation Imperial Federation.
