According to this article, Romania's 1989 revolution was actually a Christian one and not a political one. This came from the mouth of one Rev Peter Dugulescu who it says here led a prayer service in Timisoara on December 22nd which was the culmination of a week of protest. Now, according to people I have spoken to, the churches provided an important meeting place and in that sense they were a central part of the revolution. Also, the protests in Timisoara that kicked everything off, were sparked by the government's decision to silence a Hungarian Reformat priest László Tőkés, who spoke out against the system, by evicting him and subsequently attacking him physically.
But to claim that this was some kind of religious revolution misses the point quite spectacularly. I have no reason to doubt the Reverend Dugulescu when he says that he led this 100,000 strong prayer service, although this fairly exhaustive Wikipedia article, doesn't see fit to mention it. However, when he says things like "America is straying from its Christian heritage and inviting punishment unless its people come back to God" it's clear he's a couple of hassocks short of a pew. Whatever his status and his heroism in 1989, sounding off that the USA should become more fervently Christian (more!) is frankly terrifying. Bloody nutter.
