Historical Background
16th century Ireland was a strikingly different place from today’s island. There were only a few areas occupied by the English, in the cities of Cork, Limerick and Waterford and, most of all, Dublin. Each had its ‘pale’ or boundary. English manners, law, and speech prevailed inside the pale, which could be as large as 50 square miles; but what went on outside the pale was rather obscure to most Englishmen. All of Ulster was ‘outside the pale’.
Home Rule
The people of Ireland had been governed from London for hundreds of years; but they did not enjoy this domination, and built up an ever-increasing demand for self-governance. These concepts developed from the middle of the nineteenth century with a request for ‘home rule’ very similar to what is now provided, over 100 years later, in Wales, Scotland and Northern Ireland. But constant rebuttal led to a stronger and stronger demand for self-determination in Ireland; and climaxed with the Easter Rising in 1916.
However, mainly because of the historical reasons outlined above, coupled with the fear of being forced to live in state ruled by an intense kind of Roman Catholicism, many of the people of Ulster did not want to lose their longstanding parliamentary links with Westminster. These became ‘Unionist’ policies. When King George V gave his assent to the Government of Ireland Act on 23 December 1920, 26 of the 32 counties of Ireland became the Irish Free State (later the Republic of Ireland). The six counties that chose ‘partition’ were all from the province of Ulster. So this is the explanation of the common, although incorrect, assumption that the Province of Ulster, with its nine counties, is synonymous with the new state of Northern Ireland; and why others use the more correct alternative, if pejorative, title, ‘The Six Counties’.
The nine most northerly counties constitute the Province of Ulster. The long established cultural differences were compounded by the historical events of 300 - 400 years ago – the plantation of Ulster.
