History
St. Louis's current boundaries were established in 1876, when voters approved separation from St Louis County and establishment of a home rule charter. St. Louis was the nation's first home rule city, but unlike most, it was separated from any county. Baltimore also is a similarly divided metropolis. Although this boundary would in the future prove a severe limitation to the City of St. Louis, at the time there was ample room for the city to grow within its fixed boundaries. After the Civil War, St. Louis continued its rapid growth, and by 1900 was a major manufacturing center. Industries grew in St. Louis because of the city's dominance in the region, its access to rail and water transportation, and the city's central location in the nation. The 1874 construction of the Eads Bridge made St. Louis an important link in the continuing growth of transcontinental rail travel--but came too late to prevent Chicago from overtaking it as the largest rail hub in the nation. By the 1890s, St. Louis was the nation's fourth largest city.
