You could, however, accurately say that a French family founded the modern British monarchy. That much is still true. The UK royal family can still trace its lineage directly to William the Conqueror.
It’s not just the royal family, other descendants of the french conquerors are also on average wealthier than the descendants of those that had been conquered.
One pretty striking statistic: “Furthermore, Norman descendants also enjoy other privileges, including attendance at the best universities. In a recent study that examined the enrollment at Cambridge and Oxford over the last thousand years, it was revealed that at certain times, Norman names were 800% more common at Oxford than in the general population, and more recently, were at least twice as likely to found in that institution’s enrollment.”
