I want to know the answer to the following question:
What years did Abbasid caliph Harun ar-Rashid reign?
All the background I'm provided with is that "The end of the age is variously given as 1258 with the Mongolian Sack of Baghdad, or 1492 with the completion of the Christian Reconquista of the Emirate of Granada in Al-Andalus, Iberian Peninsula.". Is that enough to answer the question?
Answer: no
