During which period did the major influx of Poles to the US occur?

The major influx of Poles to the United States primarily occurred between 1870 and 1913. This was a time characterized by significant European migration to America, driven by a combination of factors, including political unrest, economic opportunities, and the availability of industrial jobs in the US. Many Poles were fleeing from a lack of political rights and harsh living conditions under foreign powers that occupied Poland at the time.

During this period, Polish immigrants settled primarily in urban areas where they found work in factories and other industrial sectors. Such communities became established, contributing to the cultural and social fabric of American cities. Understanding this historical context is crucial because it reflects broader trends in immigration and the formation of ethnic communities within the United States.

The choices reflecting other time periods do not capture the peak of Polish immigration as accurately; for example, while some Polish migrants continued to arrive in later years, the most significant numbers and establishment of Polish-American communities mainly occurred before World War I.
