William the conquerer was born in france, became first king of england, and england grows its empire over time to take over the world
france helps people fight back against england, including the revolution in the USA, who would have lost had it not been backed by the french

england also sent convicts to what is now australia and let us survive the ordeal, so now you're stuck with us on the internet in the modern era

Ergo if william hadn't been born french then become king of england, this timeline wouldn't have happened
