History of New York City (1784–1854)
The city's cosmopolitan attitude and tolerance of many different cultures encouraged many different types of immigrant groups to settle in the city. Starting in the late 1840s, the city saw increased Irish immigration with the Great Irish Famine and German immigration with the Revolutions of 1848. People who came from Ireland were poor, without knowledge of their new world; once arrived on the docks, unscrupulous landlords offered them squalid tenements which were once houses for middle-class New Yorkers. They crowded into dirty rooms, and the slums of the city became known for high rates of disease. Immigrants were skilled laborers and craftsmen, and Germans who settled in a new neighborhood named "Kleindeutschland" (Little Germany) and opened many shops where they worked as artisans. Many Irish immigrants were responsible for building the subway and sky-scrapers.
