England`s colonization strength

[motatalea]

What people that made England so strong where it became the strogest colonial empire in the world ,the Anglo-Saxons or the Normans?

[Mycernius]

I would be more inclined to say The English Channel. Unlike the rest of Europe, to invade England would require crossing the sea. England and the rest of the Isles effectively had a moat. What also helped were several moves within the country that did away with sefdom, removed certain powers from the monarch and good natural resources that benefitted a country that started the Industrial Revolution.
