Step 1 : Introduction to the question "What historical event began in earnest with "Black Tuesday" Oct. 29, 1929?"
Wall Street took a massive hit as investors began trading Oct. 29, 1929. By the end of the day, 16,410,030 shares traded through the New York Stock Exchange. This wiped out billions of dollars of wealth, devastating thousands. The aftermath plunged America and the rest of the industrialized world into the Great Depression. By 1932, stocks in the worldwide markets were worth only about 20 percent of their value from three years earlier. The stock market crash was not the sole cause of the Great Depression but it did accelerate the collapse of the global economy. Source: History.com
