Deflation
Deflation occurred periodically in the U.S. during the 19th century (the most important exception was during the Civil War). This deflation was at times caused by technological progress that created significant economic growth, but at other times it was triggered by financial crises — notably the Panic of 1837 which caused deflation through 1844, and the Panic of 1873 which triggered the Long Depression that lasted until 1879. These deflationary periods preceded the establishment of the U.S. Federal Reserve System and its active management of monetary matters. Episodes of deflation have been rare and brief since the Federal Reserve was created (a notable exception being the Great Depression) while U.S. economic progress has been unprecedented.

The Long Depression, sparked in the United States by the Panic of 1873, had far-reaching implications for US industry, closing more than a hundred railroads in the first year and cutting construction of new rail lines from of track in 1872 to in 1875. Approximately 18,000 businesses failed between 1873 and 1875, production in iron and steel dropped as much as 45 percent, and a million or more lost their jobs. In 1876, 76 railroad companies went bankrupt or entered receivership in the US alone, and the economic impacts rippled throughout many economic sectors throughout the industrialized world.
