Long Depression
In the United States, economists typically refer to the Long Depression as the Depression of 1873–1879, kicked off by the Panic of 1873, and followed by the Panic of 1893, book-ending the entire period of the wider Long Depression. The National Bureau of Economic Research dates the contraction following the panic as lasting from October 1873 to March 1879. At 65 months, it is the longest-lasting contraction identified by the NBER, eclipsing the Great Depression's 43 months of contraction. In the United States, from 1873 to 1879, 18,000 businesses went bankrupt, including 89 railroads. Ten states and hundreds of banks went bankrupt. Unemployment peaked in 1878, long after the initial financial panic of 1873 had ended. Different sources peg the peak U.S. unemployment rate anywhere from 8.25% to 14%.
Economic collapse
While arguably not a true economic collapse, the decade of the 1930s witnessed the most severe worldwide economic contraction since the start of the Industrial Revolution. In the US, the Depression began in the summer of 1929, soon followed by the stock market crash of October 1929. American stock prices continued to decline in fits and starts until they hit bottom in July 1932. In the first quarter of 1933, the banking system broke down: asset prices had collapsed, bank lending had largely ceased, a quarter of the American work force was unemployed, and real GDP per capita in 1933 was 29% below its 1929 value. The ensuing rapid recovery was interrupted by a major recession in 1937-38. The USA fully recovered by 1941, the eve of its entry in World War II, which gave rise to a boom as dramatic as the Depression that preceded it.
