The fear of foreign influence grew rapidly in America after the immigration of five million Irish and Germans 1820-60. Many of these immigrants were Catholic and by 1860, there were over 3 million Catholics in 2385 churches. The Protestant churches were divided by schisms over abolitionism, temperance, women's rights. The growth of cities and secular culture contributed to the fear and anxiety of conservative Protestants. The Antimasonic movement attracted an all-male, anti-secular, anti-modern, rural following. P.T. Barnum opened his New York museum in 1842, the same year that Edward Sorin founded Notre Dame in South Bend, Indiana. Workingmen's movements appealed to laborers who feared the loss of jobs to machines and immigrants and slaves.
