The river along the Po valley
In the late 1800s, people in many parts of the world decided to leave their homes and immigrate to the United States. Fleeing crop failure, land and job shortages, rising taxes, and famine, many came to the U. S. because it was perceived as the land of economic opportunity. Others came seeking personal freedom or relief from political and religious persecution. With hope for a brighter future, nearly 12 million immigrants arrived in the United States between 1870 and 1900. During the 1870s and 1880s, the vast majority of these people were from Germany, Ireland, and England--the principal sources of immigration before the Civil War.
Immigrants entered the United States through several ports. Those from Europe generally came through East Coast facilities, while those from Asia generally entered through West Coast centers. More than 70 percent of all immigrants, however, entered through New York City, which came to be known as the "Golden Door." Throughout the late 1800s, most immigrants arriving in New York entered at the Castle Garden depot near the tip of Manhattan. In 1892, the federal government opened a new immigration processing center on Ellis Island in New York harbor.
Although immigrants often settled near ports of entry, a large number did find their way inland. Many states, especially those with sparse populations, actively sought to attract immigrants by offering jobs or land for farming. Many immigrants wanted to move to communities established by previous settlers from their homelands.
