The fledgling Irish government did not want a partition. It happened because the British government insisted on it.
No, it happened because the majority of people in those counties (gerry mandering is a separate thread, I don't know how much difference it would have made) did not want to become citizens of the new Irish state, and wanted to stay British citizens.
To the extent of being prepared to enter armed conflict over it.
That is why anyone would take issue with that poster coming on this thread and shouting about "the Brits" taking the 6 counties from us".
It's nonsense.
The "Brits" would probably have been quite happy to wash their hands of the island entirely.
That became a million times more the case when the Troubles began and it became a colossal financial drain and their soldiers were being killed on a daily basis.
But I'm accused to taking part in a bun fight, just be pointing out the fallacies of that posters very extreme (and totally inaccurate).opinions.
The most common misconception I encounter from people from everywhere - England, the US, Spain ... Is that NI was taken/kept by the "British" and should be "freed".
The total & utter ignorance about, and dismissal of, the millions of people whose ancestors settled here centuries ago (often before the US was colonised, before Australia was colonised etc) and who did not want ... and still do not want to be citizens of the Irish state, and desperately want to continue to be British citizens ... Is beyond frustrating.
