This paper discusses the careers and accomplishments of three men who were the de facto leaders of the organized Polish American ethnic community between 1939 and 2005. It shows how they gained and held power in organizations that allowed them to represent the concerns of a large and diverse ethnic community. Each individual played a key role in both defining the Polish community's concerns about Poland, its historic homeland, and articulating these concerns to America's highest elected public officials. This case study underscores the importance of American Polonia, one of the more significant, yet all too little examined organized ethnic groups in American pluralist politics in the second half of the 20th century by focusing on the careers of Charles Rozmarek, Aloysius Mazewski, and Edward Moskal.
