Which 19th-century stock exchange crash helped spread the Panic of 1873 from Vienna to other markets?

The Vienna Stock Exchange crash helped spread the Panic of 1873 from Austria to other markets. On May 9, 1873, share prices in Vienna collapsed after a period of intense speculation in companies, railways, and property.

The crash followed the boom associated with Vienna's World Exhibition, which opened that May. Easy credit and expectations of continued growth had encouraged investors to buy shares at inflated prices. When confidence broke, many speculative companies failed, and financial distress spread through the Austro-Hungarian economy.

The panic then reached Germany and the United States, where the failure of the banking firm Jay Cooke & Company in September 1873 helped trigger a major market crisis. The resulting depression lasted for years in many countries and is sometimes called the Long Depression. The Vienna crash was an important opening shock, while the later American failures formed a separate but connected phase of the international downturn.
