The Irish people left Ireland in large numbers between 1820 and 1899 due to the potato famine and lack of work, with around 3 million Irish immigrants arriving in New York. When they arrived in New York, many Irish settlers lived in the crowded and impoverished Five Points area of Manhattan. While conditions were difficult, the Five Points district also served as a cultural melting pot where the Irish and other immigrant groups exchanged ideas and influences that later developed into musical genres like jazz and rock and roll. Today, the Irish community remains an important part of New York's history, culture and population.
