This period of time is known as Black Friday. In 1869, two people named Jay Gould and James Fisk, considering that at the time gold was still used as international currency, sought to corner the gold market by purchasing every single gold unit they could get their hands on. This caused the price of gold to highly rise for a small period of time, but having discovered the scheme of these two, former President Grant released millions of dollars in gold on a Friday. This release caused the price of gold to plummet, and the country entered economic turmoil.
