In the early 19th century, Manhattan grew in population and economically. Another great fire in 1835 destroyed much of the city but it was soon rebuilt. Because of the Great Irish Famine, a lot of Irish people emigrated (left their country) to live in New York; they made up for 25% of Manhattan's population at the time. Many of the Irish people lived in a part of the Lower East Side known as the Bowery or in another section called Five Points.
