Part of the reason for the extent of the world economic collapse of 1929 to 1933 was that it was not just one crisis but, as I describe, a sequence of crises, ricocheting from one side of the Atlantic to the other, each one feeding off the ones before, starting with the contraction in the German economy that began in 1928, the Great Crash on Wall Street in 1929, the serial bank panics that affected the United States from the end of 1930, and the unraveling of European finances in the summer of 1931. Each of these episodes has an analogue to a contemporary crisis.
