History of Europe

The first wave of European immigrants to arrive in the US in the nineteenth century came from Ireland. Between 1820 and 1860, roughly 2 million Irish immigrants arrived in the US, fleeing from the Great Famine of 1845-1852. During this period, Ireland experienced a series of crop failures, particularly of potatoes, which was a staple food for the Irish population. The famine caused widespread poverty, disease, and death, leading many Irish people to seek better opportunities in the United States.
