Hi,
Is the bold sentence correct?
The Anglo-Saxons conquered England in the fifth century. Then, the Normans came in the eleventh century. I always wonder who was there before the Anglo-Saxons? The Anglo-Saxons conquered England from whom?
You don't conquer some place from somebody. You conquer some place or you conquer somebody.
eg Who did the Anglo-Saxons conquer in England?
Best wishes, Clive
