Thank you. The Mongolian empire is often underestimated. It was huge considering it relied so much on the horse. The British empire is unlikely to be surpassed, though, especially in matters of influence through the English language and the spawning of a whole gammit of top tier nations compounding that influence still further: USA, Australia/New Zealand, Canada, India/Pakistan regions, and eventually a more successful ex-colonial Africa, .. the list goes on and on. As for the Hackney and Liverpool empires, well .. their reputation is already resounding on other planets ! No mere earthly empire can top that !
