The social pressures that contributed to English colonization of north America had to do with religious, politics and economics matters.
Bearing in mind that religion was the main factor contributing to the English migration, the Puritans fled to America from England to gain their religious freedom. England had broken away from the Roman Catholic Church and created a new church called the Church of England. However, the Puritans did not recognize the King as the head of the Church; for that reason they were persecuted.
British people were also enthusiastic about the idea of Capitalism which involved investing the capital in a growing business so as to make even more money. They believed that moving to the North American Colonies was a great opportunity to make money. Besides, people who had been oppressed in England and who had lost their jobs and homes, decided to settle down in America in order to gain land from the great vast fields so as to make their own living by working on the land.
