What was the 1873 stock-market crash in Vienna commonly called?

The 1873 Vienna stock-market crash was commonly called the Gründerkrach.

The German term Gründerkrach means “founders’ crash” and refers to the collapse of a speculative boom in Austria-Hungary and Germany. During the preceding Gründerzeit, rapid industrialization, new company formations, and easy credit encouraged investors to buy shares at inflated prices. The Vienna stock exchange fell sharply on May 9, 1873, after confidence deteriorated and speculative companies could no longer justify their valuations.

The crash followed the Vienna World’s Fair, which had helped symbolize the era’s optimism, and its consequences spread through European financial markets. It is closely associated with the Long Depression, a period of weak prices and slow growth that followed the crises of the 1870s. The Gründerkrach is sometimes confused with the U.S. Panic of 1873, but the Vienna event was a major European component of the wider international downturn.
