Dilemmas such as land shortages, religious persecution, crop failure, and unability of landing (a) job (s), increasing rate of taxes, and famine, caused many immigrants to settle in the U. S. because it was perceived as the land of economic opportunity. Especially in the urban areas, where immigrants could experience a new era of industrial change. (Second Industrial Revolution)
This movement of immigrating to urban areas in the late 1800s and early 1900s is now known as the urbanization.
It was a trade route over the sea. It contributed in the slave trade between Africa, Cuba, and the USA (might be called the American Colonies, depends on the time)
