> forced conversion, ethnic cleansing etc. - would come later.

That's not really something Muslim states do. There are massacre in war times, there are individual war bands who harass minorities. There are heavy discriminations (ghetto like conditions, special tax and humiliating laws). But mass conversion and ethnic cleansing is more of a Iberian Christian thing than something Muslim states did historically (I'm talking about antiquity and medieval period here, 18-19th centuries are a totally different thing and are more closely related to nationalism than anything in the case of Turkey for example).
