Cincinnati is considered to have been the first major American boomtown rapidly expanding in the heart of the country in the early nineteenth century to rival the larger coastal cities in size and wealth. As the first major inland city in the country, it is sometimes thought of as the first purely American city, lacking the heavy European influence that was present on the east coast. However, by the end of the century, Cincinnati's growth had slowed considerably, and the city was surpassed in population by many other inland cities.
