Book excerpt: Near the beginning of the twentieth century, thousands of Polish immigrants embarked upon the American Dream in Worcester as the city's lowest-paid mill workers. Slowly, they carved out their own "Polonia," with Millbury Street as the center. By the 1920s, Worcester's Polish community had built a parish with the largest parochial school in the county, established several civic associations, and become an influential group in the city's economy and ethnic composition. The Polish Community of Worcester celebrates the resilient and patriotic spirit of Worcester's Polonia from 1870 through 1970, with rare photographs from private collections and family albums.
