One could argue the English could have held a grudge against their subjugators in the manifestation of the Normans who took all the English lands and made it their own as well as foisted their new-to-them old French influenced Norman language. They could have held that grudge but they didn't. They subjugated and were coöpted by the Normans and then forming this new hybrid identity went on to become one of the greatest empires on Earth. Had they gone with the precursors and the likes of Winstanley I'm not certain they'd have accomplished so much and the English the Anglosphere begot by said empire would not exist today nor the world we enjoy today.

The world would be much more fragmented, if not more Frankish and perhaps Spanish.
