What was one of the main reasons that large numbers of irish moved to the united states in the 18405?

Potato Blight

Ireland’s 1845 Potato Blight is often credited with launching the second wave of Irish immigration to America. The fungus which decimated potato crops created a devastating famine. Starvation plagued Ireland and within five years, a million Irish were dead while half a million had arrived in America to start a new life.
