Below are the five causes of the great depression, describe how these causes contributed to the largest economic decline of the 20th century.

1: the stock market crash (673):

2: crisis in the farm sector (674):

3: falling purchasing power and rising unemployment (674):

4: banking crisis (675):

5: international economics (676):

The answers are:

1- It accelerated the global economic collapse of which it was also a part of.

2- The agricultural sector of the economy was struggling due to drought and falling food prices.

3-Americans forced to buy on credit and wages falling were the main reason.

4-  Americans feared that banks would soon fail, immediately began to withdraw funds from their accounts, causing thousands of banks to close.

5-Gold standard, which was a common point for nearly all the countries of the world in a network of fixed currency exchange rates, played a key role in transmitting the American downturn to other countries.

Explanation:

1-On October 29, 1929, Black Tuesday hit Wall Street as investors traded some 16 million shares on the New York Stock Exchange in a single day. Billions of dollars were lost, wiping out thousands of investors.  Many american companies spiraled downward into the Great Depression (1929-39).

2-During World War I, farmers worked hard to produce record crops and livestock.  In the early 1930s prices dropped so low that many farmers went bankrupt and lost their farms.  As an example of this some farm families began burning corn rather than coal in their stoves because corn was cheaper.

3-Many Americans forced to buy on credit fell into debt, and the number of foreclosures and repossessions climbed steadily. Those who were lucky enough to remain employed, wages fell and buying power decreased.

In 1929, consumer spending begun declining.

4-. Prior to the crash, banks participated in the practice of speculation buying, in which they often used investors`. Investors could not repay what they borrowed, and banks could not repay the investors from whom they had borrowed.

5-Although it originated in the United States, the Great Depression caused drastic declines in output, severe unemployment, and acute deflation in almost every country of the world.

especially research the treaty of greenville and the treaty of colerain in washington's administration.   also research at least one significant treaty from the administrations of adams, jefferson, and madison. tell the outcome of each treaty and how it did or did not in the further development of the west.

treaty of greenville (1814) the treaty of greenville (1814) was called a treaty of peace and friendship between the united states of america and the tribes of native americans called the wyandots, delawares, shawanoese, senacas and miamies.

the treaty of colerain was signed at st. marys, georgia in camden county, georgia, by benjamin hawkins, george clymer, and andrew pickens for the united states and representatives of the creek nation, for whom indian trader langley bryant served as an interpreter, on june 29, 1796, proclaimed on march 18, 1797, and codified as 7 stat. 56. colerain was a small community and the site of a u.s. indian factory founded by james seagrove.  

this treaty affirmed the binding of the treaty of new york (1790). the treaties of hopewell and the treaty of holston (1791) established boundary lines between the choctaws, chickasaws, cherokee, and the u.s. the treaty of colerain bound the creek nation to acknowledge the boundaries established in those treaties.  

it also established the boundary line between the creek nation and the united states. at the time of this treaty, the boundaries between spanish florida and the u.s. had not yet been established. this treaty formally allowed the creek chiefs to acknowledge the negotiation for delineating the georgia-florida boundary with spain.  

the treaty contained a provision that the president of the u.s. may establish a trading or military outpost.  

the united states demanded that the creeks give up their american prisoners and also return all "citizens, white inhabitants, negroes and property" taken by the creeks.  

the treaty describes when it would take effect. after the treaty had been signed but not yet promulgated, the u.s. senate requested modification of two articles of the treaty. the first modification stipulated that the military or trading posts would be under the control of the united states. the second modification stipulated that if the u.s. no longer required the use of those posts, the locations would revert to the creek people.
