Why They Came
Not many decisions could have been more difficult for a family to make them to say farewell to a community where it had lived for centuries, to abandon old ties and familiar landmarks, and to sail across dark seas to a strange land. Today, when mass communications tell one part of the world all about another, it is quite easy to understand how poverty or tyranny might force people to exchange an old nation for a new one. But centuries ago migration was a leap into the unknown. It was an enormous intellectual and emotional commitment. The forces that moved early immigrants to their great decision — the decision to leave their homes and begin an adventure filled with uncertainty, risk and hardship — must have been of overpowering proportions. As Oscar Handlin states, the early immigrants of America "would collide with unaccustomed problems, learn to understand alien ways and alien languages, manage to survive in a very foreign environment".
Despite the obstacles and uncertainties that lay ahead of them, millions did migrate to "the promised land" — America. But what was it that moved so many to migrate against such overwhelming odds？ There were probably as many reasons for coming to America as there were people who came. It was a highly individual decision. Yet it can be said that three large forces—religious persecution, political oppression and economic hardship-provided the chief motives for the mass migrations to America. They were responding in their own way to the pledge of the Declaration of Independence: the promise of "life, liberty and the pursuit of happiness".
The search for freedom of worship has brought people to America from the days of the pilgrims to modern times. In 1620, for example, the Mayflower carried a cargo of 102 passengers who "welcomed the opportunity to advance the gospel of Christ in these remote parts". A number of other groups such as the Jews and Quakers came to America after the Pilgrims, all seeking religious freedom. In more recent times, anti-Semitic persecution in Hitler's Germany has driven people from their homes to seek refuge in America. However, not all religious sects have received the tolerance and understanding for which they came. The Puritans of the Massachusetts Bay Colony showed as little tolerance for dissention beliefs as the Anglicans of England had shown them. They quickly expelled other religious groups from their society. Minority religious sects, from the Quakers and Shakers through the Catholics and Jews to the Mormons, have at various times suffered both discrimination and hostility in the United States.
But the diversity of religious belief has made for religious toleration. In demanding freedom for itself, each sect had to permit freedom for others. The insistence of each successive wave of immigrants upon its right to practice its religion helped make freedom of worship a central part of the American Creed. People who gambled their lives on the right to believe in their own God would not easily surrender that right in a new society.
The second great force behind immigration has been political oppression. America has always been a refuge from tyranny. As a nation conceived in liberty, it has help out to the world the promise of respect for the rights of man. Every time a revolution has failed in Europe, every time a nation has succumbed to tyranny, men and women who love freedom have assembled their families and their belongings and set sail across the seas. This process has not come to an end in our own day. The terrors of Hitler's Germany and Mussolini's Italy, the terrible wars of Southeast Asia — all have brought new thousands seeking safety in the United States.
The economic factor has been more complex than the religious and political factors. From the very beginning, some have come to America in search of riches, some in flight from poverty, and some because t
