There is a pattern across all history and the rise and fall of these empires. Their rise mirrors their fall. Through brutal military conquest and clever political exploitation did the British empire conquer the world, and so by brutal revolts and the political breakdown of Europe did it collapse. The Roman Empire was built upon a seemingly never ending core of labourers and soldiers, whose constant effort in wars and statecraft ultimately led to dominance unheard of for their era. Yet, after centuries of constant struggles with seemingly endless enemies, their empire collapsed.
