They and the Saxons both invaded the island and saturated it, enough that the Celtic peoples resident there beforehand became minority groups, more prevalent in Cornwall, Wales, and Scotland.
So you get people conflating ethniticity ("Anglo-Saxon") with citizenship ("English"). In a country like Sweden, where the ethnic group is literally "Swedes", and there's even less distinction, this difference becomes way easier to conflate and it can get confusing.
You'd be Swedish by citizenship, not Swedish by ethnic origin (though you may be adopting Swedish culture, and may intermarry with ethnic Swedes, blurring the divide, because none of these are clean lines).
Yes, this is all annoying garbage. Playing the ethnicity police isn't helping anything, anywhere, not unless your ethnic group is literally being subjected to genocide. Anyone trying to argue you're not "really Swedish" in terms of citizenship, because of your ethnic origin, is a racist shitbird.
