Sort of thinking how three of the biggest non Muslim countries (Russia, India, and China) all have a large and historical Muslim minority but America doesn’t. Suppose the POD is that Islam spreads to the coastal areas of West Africa and eventually supplants the polytheistic faiths there for good in a process that lasts from the 14th to 17th centuries. When the slave trade begins the slaves are brought to the United States but are not converted to Christianity (though I imagine a few would be - maybe a 75-25 ratio). How do the presence of Muslim slaves impact the history of the United States?
