thousands of years ago britain was physically joined to europe cos most of the north sea and the channel did not exists, there was just land that later flooded (I know "britain" didnt exist then it was just "land" - "countries" are relatively modern concept)
so people from europe migrated to it (and they came from the middle/far east/ africa)
then the romans migrated there
then the anglo saxons did
then the vikings did,
then the normans did
(think the order is wrong)
over time people from all over the world migrated to britain , just as people from britain migrated in the other direction (cant exactly call them "british")
You think britain today is the same as it was say 10000 years ago and all that migration didnt change a thing or what?
And actually there are VERY few people in britain that are descendants of the original "british"
You think YOU are british?
I would strongly recommend you have your DNA profile done
you send a swab from inside your mouth and they compare it with samples of DNA taken from people all over the world
In DNA there are chunks of it that are very specific to different areas
If your DNA has that chunk then its VERY likely one of your ancestors came from that area
As a result you can get a probability of where your distant ancestors came from
Its VERY likely you will get a surprise
(the ancestors of that well know buffoon boris johnson came from turkey)
(".i really feel nostalgic and miss the past, how Britain used to be"
Oh do grow up , the britain today is not the same as it was 10 years ago
the britain 10 years ago was not the same as 20 years ago
there has NEVER been a time when the britain of one day was the same as it was 10 years before
Britain has ALWAYS been changing -
YOU may prefer the britain of 1970 to that of 2017
But I prefer the britain of 1960 to that of 1970
and I prefer the britain of today to that of 1970
100 years ago YOU would not be living in a council flat- cos they didnt exist
100 years ago YOU would not be living off benefits - cos THEY didnt exist either
100 years ago YOU would be living on the streets and looking for a job ANY job, cos without it you would starve
(or more likely - getting killed in WW1)
Nostalgia is NEVER what it actually used to be, its only what you THINK it used to be
the effect of time on memory is that you remember the good things of an era but forget/ignore the bad things
