Which country suffered the 1929 stock-market crash known as the Great Crash?

The 1929 stock-market crash known as the Great Crash occurred in the United States, centered on New York's Wall Street.

The New York Stock Exchange was the world's most prominent securities market, and its collapse became the most famous financial event of the interwar period. After years of rising share prices, the market turned downward in October 1929. The selling intensified on Black Thursday, Black Monday, and Black Tuesday, although the decline continued afterward.

The crash began in the United States but quickly affected economies and financial markets elsewhere. American banks and investors reduced lending, international trade weakened, and banking failures multiplied. Historians generally treat the crash as a major trigger or accelerator of the Great Depression rather than as its only cause. The United States designation matters because other countries experienced severe market crashes in different eras, including Britain in 1720 and Austria in 1873.
