https://en.wikipedia.org/wiki/Baku_pogromAizerbaijan, a largely Muslim nation, had a pogrom against Armenians as recent as 1990; the 2 countries, Armenia and Aizerbaijan, still have misunderstandings over their borders. Reading the wikipedia article, I'm not sure if the trouble was over religion, they seem to say something about Communism. But I do know, it happened. Aizerbaijan seems to have a mainly Shiite Muslim population.
