After many years of internal struggles, the wounds were healed, but not forgotten, the peace was achieved thanks to the American values of Life, Liberty and the Pursuit of Happiness. The American dream, tells the story of the poor man who becomes a millionaire, same story that is repeated over and over again, this dream awakes the illusion of many Europeans, who devastated by war, hunger and despair, embark on a trip for a better life.

Hamburg, a city destroyed by a fire in 1842 and a revolution in 1848, sees its shipyards renewed before the foundation of the HAMBURG AMERICA LINE, a shipping company that began operating to transport people and goods. By the end of the 19th century, 52 million Europeans will leave their continent to never return.

The ships arrived in two weeks, the one-way trip carried people, the return trip, merchandise; After 14 days of quarantine, passengers passed strict controls so as not to be rejected in New York. The first class, had cabins and windows and descended in Manhattan, the third class, is where the profits came from and arrived to Ellis Island, better known as the Island of Hope and Tears.

The Statue of Liberty welcomed the new citizens with open arms: «Give me your tired, your poor, Your huddled masses yearning to breathe free, The wretched refuse of your teeming shore. Send these, the homeless, tempest-tost to me, I lift my lamp beside the golden door!

The poor arrive dressed in their best claws, and their last name gets Americanized, nevertheless many immigrants were rejected by the strict racial and sanitary measures; criminals, prostitutes, mentally ill, anarchists and alcoholics were returned to Europe. The Chinese were prohibited entry for some time due to the Chinese Exclusion Act of 1882, 25 years later the same would happen with the Japanese.

The American diversity grew, the new groups that arrived were mostly Greeks, Italians, Poles, Slovakians, Serbs, Russians, Croats, Germans, Scots and Irish. The Japanese and Chinese moved to the west coast of the United States, mainly in California.

The vast majority were Catholics and Orthodox, there were also many Protestants and Jews. Very few of the newcomers spoke English, and almost all were illiterate in their native languages. None of these groups came from democratic regimes. Democracy was as foreign to them as their culture.

American cities became the homeless shelter. Once the trend was established, ethnic enclaves of immigrants were founded, emerging in New York and other big cities, neighborhoods such as Chinatown, Greektown, Little Italy or Little Germany. This led to an urban ethnic mosaic, with little integration. However, many of these immigrants were only in the United States as birds of passage, gain some money and later on return to their countries.

This immigration policy was established by the government to populate and make the land productive, people who were looking for an opportunity to work it, found their niche pretty soon; Unlike Hispanic thought where land is a right or legacy, Americans consider land an asset. The center of the country gets fulfilled with farmers, the west coast with adventurers and the urban areas became labor centers for factories, the economy is growing by leaps and bounds.

Immigrants soon spread to populate the vast territory of the United States. The Mexican Revolution brings millions. Until the Second World War, the bulk of immigration is European, with timely contributions from Mexico, Canada or China. After the conflict, the pattern is substantially modified, by government policies, the bracero program, in the sixties, causes Mexico to begin leading immigration to the United States, accompanied by other Latin American countries such as Cuba, Colombia or Argentina. And from the seventies, the focus moves to Asia: India, China and the Philippines  and since the beginning of the XXI Century from Iraq, India, Venezuela, Iran, Pakistan, Syria and Afghanistan.

The face of the United States has changed abruptly, urban centers are an example of diversity and although the center of the country is eminently European, by 2050 these cease to be a majority, with Hispanics being the first minority and diversity, as the result of combining genetics and culture, will be the generality of this country.
