During the 19th century, New York City became the main entry point for European immigrants to the United States, beginning with a wave of Irish during their Great Famine. Millions came through Castle Clinton in Battery Park before Ellis Island opened in 1892 to welcome millions more, increasingly from eastern and southern Europe. The Statue of Liberty opened in 1886 and became a symbol of hope.
In the 19th century between 1855 and 1890, an estimated 8 million immigrants passed through New York's Castle Clinton at Battery Park in Manhattan. Early in this period, most immigrants came from Ireland and Germany. A wave of irish had came to New York and America during the Great Famine.
Ellis Island opened in 1892, and between 1880 and 1920, most immigrants were German and Eastern European Jews, Poles, and other eastern and southern Europeans, including many Italians.
By 1925, New York City's population outnumbered that of London, making it the most populous city in the world.
New York boomed during the Roaring Twenties, before the Wall Street Crash of 1929, and skyscrapers expressed the energy of the city. New York City was the site of successive tallest buildings in the world from 1913–74.
