The Great Depression began with Black Tuesday on October 29, 1929, when the stock market crashed, leading to the most severe economic downturn in modern history. The crisis spread globally, causing widespread unemployment, mass poverty, and profound social changes that would reshape society for decades.

The Great Depression stands as one of the most devastating economic downturns in modern history. While many associate its start with the stock market crash of October 29, 1929 - known as Black Tuesday - the roots of this economic catastrophe ran much deeper and began forming years before the crash.

The onset of the Great Depression wasn't a single event but rather a series of economic failures that cascaded throughout the late 1920s. From the collapse of farm prices earlier in the decade to the excessive speculation in the stock market these factors combined to create a perfect storm that would ultimately affect millions of Americans. The resulting economic crisis spread globally causing widespread unemployment mass poverty and profound social changes that would reshape society for decades to come.

The stock market crash of 1929 marked a pivotal moment in American economic history, triggering widespread panic and financial devastation. The New York Stock Exchange experienced unprecedented losses totaling $14 billion in October 1929.

On October 24, 1929 (Black Thursday), the stock market plunged as investors traded 12.9 million shares in a single day. The following Tuesday, October 29 (Black Tuesday), brought an even more devastating crash with 16.4 million shares changing hands. Stock prices fell by 89% from their peak, erasing billions in market value.

Date	Trading Volume	Market Impact
Oct 24, 1929	12.9M shares	Initial major decline
Oct 29, 1929	16.4M shares	89% value drop

The immediate aftermath saw numerous banks close their doors as depositors rushed to withdraw their savings. Wall Street executives attempted to stabilize the market by purchasing large blocks of stocks, investing $20 million to project confidence. Leading financial institutions, including Morgan Bank, National City Bank, and Chase National Bank, bought stocks at prices above market value to demonstrate market strength.

The United States economy exhibited several warning signs during the 1920s that foreshadowed the impending economic collapse. These indicators emerged across multiple sectors of the economy, creating a fragile financial landscape prone to catastrophic failure.

American farmers faced severe economic hardships throughout the 1920s as crop prices plummeted by 40% between 1919-1921. Technological advancements in farming equipment increased production capacity while European agricultural markets recovered after World War I, creating surplus supplies. Farm foreclosures rose dramatically, with 453,000 farmers losing their properties between 1921-1929. Rural banks experienced record failures, with 5,755 banks closing their doors during this period, primarily in farming communities.

Agricultural Crisis Statistics	Values
Crop Price Decline (1919-1921)	40%
Farm Foreclosures (1921-1929)	453,000
Rural Bank Failures (1921-1929)	5,755

• The richest 0.1% of Americans earned total income equal to the bottom 42%
• 70% of families earned less than $2,500 annually
• 8 million Americans lived at or below the poverty line
• The ratio between the highest-paid executives to the average worker reached 300:1

The banking crisis of 1930 marked a severe phase of the Great Depression, characterized by widespread bank failures and a collapse in the financial system. The crisis intensified the economic downturn as thousands of banks closed their doors, leaving millions of Americans without access to their savings.

Bank runs devastated the American financial system in 1930, with 1,352 banks failing that year alone. Panicked depositors withdrew $1.3 billion from banks between September and December 1930, triggering a chain reaction of closures. The Bank of United States, with deposits of $200 million representing 400,000 customers, collapsed on December 11, 1930, marking the largest single bank failure in American history at that time. Rural banks suffered particularly heavy losses, with 2,293 banks closing in agricultural regions during 1930-1931.

Public trust in financial institutions plummeted as bank failures accelerated across the country. The Federal Reserve's restrictive monetary policies reduced the money supply by 30% between 1929 and 1933, exacerbating the crisis. Depositors lost $140 billion in savings through bank failures, destroying the financial security of countless families. Media coverage of bank runs created a self-reinforcing cycle of panic, as images of crowds outside banks prompted more depositors to withdraw their money. The lack of federal deposit insurance left account holders without protection, leading to a complete erosion of faith in the banking system.

Banking Crisis Statistics 1930
Total Bank Failures	1,352
Deposit Withdrawals	$1.3 billion
Bank of United States Deposits	$200 million
Affected Customers	400,000
Money Supply Reduction	30%
Total Lost Savings	$140 billion

The Great Depression's impact extended far beyond U.S. borders, creating a worldwide economic catastrophe that affected international trade, monetary systems, and economic policies across continents. The crisis spread rapidly through interconnected financial markets and trade relationships, leading to a global economic downturn of unprecedented scale.

International trade plummeted 65% between 1929 and 1933, devastating economies worldwide. The U.S. Smoot-Hawley Tariff Act of 1930 increased import duties on over 20,000 goods, prompting retaliatory tariffs from 25 trading partners. Global commerce suffered severe disruptions:

Trade Indicator	1929	1933	Decline
World Trade Volume	$5.3B	$1.8B	66%
U.S. Exports	$5.24B	$1.61B	69%
European Exports	£2.87B	£0.97B	66%

The international gold standard amplified the Depression's severity by limiting monetary policy options. Countries maintaining the gold standard experienced:

• Deflation rates of 30% in France Spain Italy between 1929-1933
• Currency devaluation affecting 35 nations by 1936
• British pound's departure from gold in 1931 triggering 25 other nations to follow
• Fixed exchange rates preventing natural economic adjustments in international markets

Country	Left Gold Standard	Recovery Started
Britain	September 1931	1932
U.S.	April 1933	1933
France	June 1936	1937

The Great Depression's severity manifested through dramatic shifts in fundamental economic metrics. These indicators revealed the unprecedented scale of economic decline between 1929-1933.

Unemployment rates skyrocketed from 3.2% in 1929 to 24.9% in 1933, leaving 15 million Americans jobless. Manufacturing employment dropped by 31%, while construction jobs declined by 78% compared to pre-depression levels. Urban areas experienced higher unemployment rates than rural regions:

City	Peak Unemployment Rate (1933)
Detroit	45%
Chicago	40%
New York	35%
Boston	30%

The U.S. Gross Domestic Product fell sharply during the initial years of the Great Depression. Key GDP indicators show:

Year	GDP (Billions)	Decline from 1929
1929	$104.6	-
1930	$92.2	-11.9%
1931	$77.4	-26.0%
1932	$59.5	-43.1%
1933	$56.4	-46.1%

Industrial production decreased by 47% between 1929-1932. Manufacturing output dropped to 54% of its 1929 levels while mining production declined to 65% of pre-crash figures. The construction industry experienced an 80% reduction in activity by 1933.

The Great Depression transformed American society through widespread poverty affecting millions of families across social classes. Living conditions deteriorated rapidly as unemployment spread through urban industrial centers.

Makeshift shanty towns called "Hoovervilles" emerged in 1930 across major American cities, housing displaced families in crude shelters made from scrap materials. These settlements, named mockingly after President Herbert Hoover, grew to accommodate up to 15,000 residents in larger cities like New York Seattle St. Louis. Breadlines stretched for blocks as charitable organizations soup kitchens served over 85 million meals in New York City alone during 1931-1932. The American Red Cross distributed food to 300,000 families while settlement houses provided meals to 450,000 children daily.

Mass migration reshaped America's demographic landscape as 2.5 million people left their homes searching for work opportunities. The Dust Bowl drove 200,000 people from the Great Plains to California between 1930-1934, while 1.6 million Americans moved from urban to rural areas to survive through subsistence farming. African Americans participated in the "Second Great Migration," with 400,000 leaving the rural South for northern industrial cities. Industrial centers like Detroit Chicago Cleveland experienced population increases of 35% despite high urban unemployment rates.

Migration Statistics 1930-1934	Number of People
Total Displaced Americans	2.5 million
Dust Bowl Migration to California	200,000
Urban to Rural Movement	1.6 million
African American Migration North	400,000
