It depends on which era your talking about. I'm assuming your referring to the plague.

Immigration from Ireland was mostly a result of a potato famine. The reason it's called an Irish Potato is because the Irish depended greatly on the potato and when a blight was destroying the potato crops one million died and others came here.
Most of the immigration was caused by the potato famine, but some were caused when their king had switched to a England church because of his marriage. That caused England to be in control of Ireland which left them weak. Another when the black plague had spread to them from England and the Irish were mad at them cause now, England had made most of their troubles.

potato famine
Ireland suffered a massive potato famine. Many were very poor farmers and did not have anything else to eat. This was caused by a fungus called the potato blight. Thousands died by starvation and many more came to the USA.
Europe More specifically, Ireland. Irish immigrants were fleeing the potato famine and came to the US.
the potato famine
The great Irish potato famine started in the United Kingdom of Great Britain and Ireland in the years 1842 to 1852. There was mass starvation, which is estimated to of killed one million people. Many people also emigrated from Ireland because of the famine. Ireland's population is estimated to have decreased as much as 25 percent in just seven years. Historians now know the cause of the famine was a disease called potato blight. The famine was so great, because at the time nearly 33 percent of Ireland's population relied solely on potatoes for nourishment.
A famine in Ireland caused many to immigrate to the US in the mid 1800s. The Irish economy became too reliant of the potato crop which was the livelihood of about one third of the people at that time. A potato disease that had spread through Europe wasn't as serious a catastrophe until it came to Ireland, where much of the economy depended on the potato.
They came to the US....
It is not known for certain when it came to Ireland. The potato comes from South America and would have come to Europe with returning Spanish explorers in the 1570s. At sometime within the following years it would have come to Ireland, in the 1570s or 1580s. It is often said that Walter Raleigh brought the potato to Ireland, but that is not certain and generally regarded as a myth.
