With increasing migration, from the 1830s to the 1860s, Missouri's population almost doubled with every decade. Most newcomers were American-born, but many Irish and German immigrants arrived in the late 1840s and 1850s. As a majority were Catholic, they set up their own religious institutions in the state, which had been mostly Protestant. Many settled in cities, creating a regional and then state network of Catholic churches and schools. Nineteenth-century German immigrants created the wine industry along the Missouri River and the beer industry in St. Louis.
