What were the consequences of the partition of Ireland?

Answer 1

The main consequences were to create a very separate society in the North, which moved on closely in industry and foreign policy with Britain, while Southern Ireland went it's own way. The split caused a lot of resentment among northern Catholics and nationalists who felt they were forgotten about by their southern brethren, and who suffered discrimination at the hands of a predominantly unionist and Protestant government. It also led to the ressurection of the IRA, who have perpetrated many acts of violence in the North since then, as have their unionist counterparts. The main consequence of division has been to emphasise and build upon divisions and differences between southern and northern Ireland to such an extent that it is very difficult to see them ever being reunited again.

Answer 2

To answer that in full would be a very extensive answer and would require delving back into Ireland's history for hundreds of years before partition. So in very simple terms it created Northern Ireland and what is now referred to as the Republic of Ireland. It started a civil war in Ireland, though it only lasted for about 11 months. It created a split in Irish politics which gave us the two main political parties that the Republic of Ireland has had since then, Fianna Fáil and Fine Gael.

The creation of Northern Ireland created problems within it which really erupted in the 1960s and frequently brought Ireland into international news headlines after that. From outside of Ireland there have been many misconceptions about it, like people thinking it was all over Ireland or that it was specifically about religion and that it was an all out war and other such misconceptions. To explain Northern Ireland and its problems would also require an extensive answer.

So the consequences of the partition of Ireland were many and complex, as this brief answer might give you an idea of. Some continue to this day. There were consequences in many ways, political, social, economical etc. You would really need to study it indepth and get different perspectives on it, as different people look on it in different ways. Irish history is like that.
