The main cause of the Great Migration to the US in the late 1800s and early 1900s was a need for workers in the US. The US was experiencing rapid industrialization and expansion and needed a large workforce to support this growth. Many immigrants came from Europe and other parts of the world seeking economic opportunities and the chance of a better life. Political unrest in Europe and religious persecution in Eastern Europe were also contributing factors, but the need for workers was the main reason for the influx of immigrants during this time period. Scarcity and the lack of money could also be a contributing factor for some immigrants who were seeking financial stability and prosperity in the US.
