Random Wikipedia Article of the Week No. 1

So, I wanted some way to make me post at least once a week, so I thought: why not some sort of weekly event? Redundant, yes, but effective. So, I decided to do a random Wikipedia article (that I liked) of the week. You are sure to NOT find stubs, articles about most musical groups, most disambiguation pages, or things I'm not interested in. I'll just post this week's link here:

http://en.wikipedia.org/wiki/Anglo-Irish_Treaty

I didn't read the article, but it seemed to have some sort of historical significance, so here it is.
