The first thing this timeline reminded me of, is this: People often make a sweeping assumption that "British" people are "Anglo-Saxon". This is wrong for a whole host of reasons. One of those reasons is me, and millions like me - Celts. I was reminded that, in fact, the Celts started arriving here in 400 BC, whereas the Angles and Saxons didn't start arriving here until the best part of a millennium later, in 390 AD. So yaboo sucks to you Saxon lot!
The time line also highlights how long ago many ethnic groups starting arriving on our shores:
250AD - First black people arrived here as part of the Roman legionaires
1507 - There was a black trumpeter at the court of Henry VII
1510 - People from the Punjab arrived here
1555 - More substantial numbers of Black people arrived as slaves from Africa
1650 - Chinese and West African "Lascars" arrive
1685 - Thousands of Huguenots fled here
1770s - 20,000 Black people were living in London at the end of the 1700s plus another 4,000 in the rest of the country.
1820 - Chinese communities take root
1840 - Substantial numbers of skilled Indian workers arrive plus those from Italy and Southern Europe
1890 - "Chinatown" established in London
1916 - Carribeans arrive to aid the war work
1940 - RAF have shortage of pilots. Pilots from the Carribean, South Africa, India and Eastern Europe (especially from Poland and Czechoslovakia) arrive.
