Book excerpt: Winner of the Herbert H. Lehman Prize by the New York Academy of History. In The Rise and Fall of Protestant Brooklyn, Stuart M. Blumin and Glenn C. Altschuler detail how nineteenth-century Brooklyn was dominated by Puritan New England Protestants and how their control unraveled with the arrival of diverse groups in the twentieth century. Before becoming a hub of urban diversity, Brooklyn was a charming "town across the river" from Manhattan, known for its churches and suburban life. This changed with the city's growth, new secular institutions, and Coney Island's attractions, which clashed with post-Puritan values. Despite these changes, Yankee-Protestant dominance continued until the influx of Southern and Eastern European immigrants. The Rise and Fall of Protestant Brooklyn explores how these new residents built a vibrant ethnic mosaic, laying the foundation for cultural pluralism and embedding it in the American Creed.
