1.Black Tuesday: Black Tuesday took place on October 29, 1929 and was the fourth andlast day of the stock market crash of that year. This is due to panicked sellers who tradednearly 16 million shares on the New York Exchange (four times the normal), and theDow Jones Industrial Average fell -12%. Black Tuesday is often cited as the beginning ofthe Great Depression, the deepest and longest-lasting economic downturn in the historyof the Western industrialized world up to that time. Billions of dollars were lost, wipingout thousands of investors, and stock tickers ran hours behind because the machinerycould not handle the tremendous volume of trading. After Black Tuesday, stock priceshad nowhere to go but up, so there was considerable recovery during succeeding weeks.The effects on the economy will not get better until the year 1939, when World War II(1939-45) fortified the American industry, where the economy would fully turn around.a.2.The Dust Bowl: The dust bowl were a series of periodic dust storms, between 1930 and1940, in the midwestern part of the united states, created by the erosion and the dry farmsof the area. Wheat started to rise in prize during World War II, which made rush to plantsome wheat of their own.The dust bowl severely destroyed the ecology of the Midwest,while at the same time forcing a massive migration of 300,000 people out of the DustBowl states, including Oklahoma, New Mexico, Kansas, Colorado, and Texas causing thearea to lose 60% of the population. One of the main causes to form this drought was theovercultivation that caused the soil to lose its rich qualities. When the soil became plainsand, then strong winds started to blow and therefore creating sand storms. It became oneof the worst environmental. Solid conservations were made by the U.S during 1935,which consisted of better planting techniques and by replacing the lost vegetation. It issaid that this was the worst ecological disaster in American History. a.3.Bank Holiday: It was the last four days before the banks broke down. It created theEmergency Banking Act, where the treasury department would make sure that in any caseof a bank collapse again they would give back the money lost. After this, only 50% ofbanks were functional.a.4.Fascism: It was a radical and authoritarian nationalist political ideology. “Ein Volk, einReich, ein Fuhrer, One people, one nation, one leader” was said by Hitler.
