Yes, it's helpful to know the tenets of religion and a bit of their history - but, that is not the focus for our class. We have to discuss religion in terms of geopolitics. Basically, how places and people interact with one another. Without political borders conflicts were going to bicker.

For this topic you should be able to:

Political rivalries between the Ottoman and Safavid empires intensified the split within Islam between Sunni and Shi’a.
Sikhism developed in South Asia in a context of interactions between Hinduism and Islam.
