They believe the blight came out of Mexico and it's affecting potato shipments in the Northeast out of New York and Boston by the early 1840s. And by 1843, 1844, it's reached Europe and Ireland, of course, as well. The difference between Europe and Ireland is that Europe isn't self-sufficient on the potato crop. They have a lot of variety. And Ireland did too, but that variety is being sent back to Great Britain for a profit. So by 1846, with something like 75% of all the potatoes destroyed by this blight, there really is nowhere for these Irish Catholics to turn. They're dying by the tens of thousands.
