A history of immigration into Britain:
- Romans
- Anglo-saxons
- Vikings
- Normans
- Huguenots
- Romani
- Indians
- Africans
- Russian Jews
- Germans
- Hungarians
By the way we're only up to approximately the mid 1950s now, long before Blair landed on the scene.
You forgot the Celts, who were also immigrants or at least it was an imported culture. Who knows. But it is these iron age people who leave the largest traces in British, including English, peoples DNA today
Not sure all those mentioned in the list are great examples of successful immigration though
The Roman's ruled for over 400 years, built roads, infrastructure, towns and cities but it wasnt a peaceful invasion. Far from it.
The widespread slaughter and bloodshed of the Norman Conquest was a huge genocide of the innocents. Leaving so much famine and destruction in its wake that some refugees were sent fleeing across the whole continent of Europe.
There is a difference between invasion and immigration, and also differences in how those different immigrant people successfully integrate and how quickly.
