New map of Belfast protestant/catholic populations.

Well not really.. Its just a teaser for what will be. What is new is that what you are looking at are the outlines of new Belfast. All that I've read so far is that these new divsions will give a nationalist majority in the council  chambers. Time will tell.

Irish civil war in 1922. Division of the island into republican and free-state areas.

So Dongeal Clare, Laois, Westmeath, Meath, Cavan, Monaghan and parts of other counties were Free-State territories. This is I did not know. To be honest im quite surprised by the amount of territory that the Republicans had. I assumed it was more heavy towards the Free-Staters. I can not remember where i found this map.

New Northern Ireland Councils

Middle map shows the old system.  Below is the wikipedia summary of the changes. I'm guessing that fear politics are behind the fact that belfast is not taking in parts of "natural belfast" such as forestside.
