Answer:
They were all Islamic, though some were Sunni and some were Shi'a
Explanation:
Hi there,
These three empires were predominantly Muslim. However, the religious tolerance between these three empires varied.
The Ottoman Empire is pretty much modern-day Turkey and nearly 100 percent of the population there are Muslim. The Safavid Empire was in modern-day Iran and most people should know that Iran is run by a Sharia Law. Lastly, the Mughal Empire was in modern-day India and was a combination between Muslims and Hindus.
Hope this gives you some general ideas about this topic. Cheers.
