it was a treaty between the UK and the then irish delagation (didn't become a republic until 1937)
Yes there were provisions that those counties that wished to opt out of the treaty could do so, but that's what the majority of the residents of those counties wanted.***
no.. the treaty gave 26 counties of "southern" ireland "home rule" in the form of the irish free state not independance.. the six counties of northern ireland were never part of the signed treaty.... the citizens of the 26 counties had a vote on the anglo-irish treaty and accepted it... the six counties of northern ireland never voted on the treaty.
