I'm curious to know why the Irish depended on potatoes so much and could't plant another crop like wheat or corn. I understand the climate may have some restrictions on what you can grow but potatoes are a new world crop not native to Ireland. I asked my U.S. history teacher about this and he kinda just passed it off as I was an idiot and had no idea what I was talking about. I understand potatoes can feed a family and were also a cash crop but why didn't they plant something else. Did the Crown and Parliament restrict them from doing so or was there some sorta issue that prevent them from trying to plant anything else. For anyone who has information for an answer and shares thank you in advance.
This answer by u/ParkSungJun explains how the systemic privatisation of land ownership that developed in Ireland under British rule in preceding centuries led to a situation where plenty of other crops such as wheat and oats were grown, but were on the estates of landlords who grew them for export to Britain, while poor people had to make do with tiny plots of land for their own personal food supply.
