Building global movement requires reading documents about societies, like this one [1] is. Analysis is fully accurate, although 7 years old and some changes have happened in the mean time.
So, to understand the circumstances around building community or chapter in particular country, I strongly suggest reading relevant cables.
And, BTW, Wikipedia articles could be improved thanks to those cables.
