I want to know the answer to the following question:
What year marked the onset of the Crusades?
All the background I'm provided with is that "With the onset of the Crusades in 1095, and the expulsions from England (1290), France (1394), and parts of Germany (15th century), Jewish migration pushed eastward into Poland (10th century), Lithuania (10th century), and Russia (12th century).". Is that enough to answer the question?
Answer: yes
