By comparison the Mongols trod lightly on the world they conquered. They brought no distinctive architectural style with them. Nor did they seek to impose their language and religion on the conquered since in most cases they forbade non-Mongols to learn their language.
This seems a little contradictory. Weatherford said earlier that Kubilai Khan attempted to create a universal alphabet. The Mongols also implemented plenty of other political and social reforms as noted in this book. I guess he does preface this statement with "by comparison", but I think it's still reaching a little.
