I want to know the answer to the following question:
When did the expulsion of Jews from Spain and Portugal occur?
All the background I'm provided with is that "In addition, there is a differentiation made between Sephardi migrants who established themselves in the Middle East and North Africa after the expulsion of the Jews from Spain and Portugal in the 1490s and the pre-existing Jewish communities in those regions.". Is that enough to answer the question?
Answer: yes
