ABSTRACT
The state that is called Britain, for short, in this book is formally the United Kingdom of Great Britain and Northern Ireland. It was the United Kingdom of Great Britain and Ireland from 1801 until, after a bloody guerrilla war, Ireland was partitioned in 1921. The treaty gave effective independence to the greater part of Ireland – which became a republic in 1949 – while six counties in the province of Ulster remained in the UK, with a ‘home rule’ system and a Northern Ireland parliament at Stormont in Belfast. But the border was kept open; and Irish migration to Britain continued.
