Potato Blight
Yes, Potato blight is endemic in Ireland and Europe, but today a variety of types of potato are grown some of which are blight resistant and we also have chemical sprays that can kill the fungus. The trouble with the blight in the past was that there were no sprays and only one variety of potato was grown and when a blight evolved to attack this variety, it meant that ALL the Irish crop was hit and this lead to famine.
The potato blight.
Potato blight in Ireland in 1845 was caused by the pathogen Phytophthora infestans, which thrived in the damp, cool conditions of that summer. The disease spread rapidly through contaminated seed potatoes and the movement of infected plants. It devastated potato crops, which were a staple food for the Irish population, leading to widespread famine and suffering. The blight's impact was exacerbated by the reliance on a single potato variety, making the crop particularly vulnerable to disease.
I think the potato blight first arrived in Cork onboard ships from the US, then spread to the rest of Ireland
The English, who had no use for the Irish, spread the potato blight germs around on the potato fields so that they could get rid of as many Irish as possible. It largely worked - millions of Irish either starved to death or immigrated to other nations, like Canada and the USA. (That's why my greatgreatgreatgreatgreat grandfather came to America)
The potato blight and the British abandoned Ireland and let everyone to die
Ireland had a potato famine, caused by potato blight. It ran from 1845 to 1849. As a result of the dependency of people on potatoes at that time, millions died or emigrated, causing a major reduction in Ireland's population. Before the famine it was over 8 million. It still hasn't reached that level again, with the population now over 6 million.
During the period from 1845 to 1852, Ireland suffered a famine due to the potato crop getting potato blight which destroyed the crop.
