I want to know the answer to the following question:
In what year did Sultan Selim I order the massacre of 40,000 people whom he considered heretics?
All the background I'm provided with is that "With these conquests, Selim further solidified the Ottoman claim for being an Islamic caliphate, although Ottoman sultans had been claiming the title of caliph since the 14th century starting with Murad I (reigned 1362 to 1389).". Is that enough to answer the question?
Answer: no
