Why did the us stock market crash in 1929 affect other nations

trade with US decreased and hurt countries who relied on the US for resources.

Because the American economy was strengthened by the disaster that caused the First World War in Europe. The United States of America became the main creditor country on the planet. The investments and merchandise of the United States began to dominate the spaces in the European countries.

In mid-1928, US investors restricted the purchase of bonds in Europe, especially German securities, and channeled investment funds to the New York Stock Exchange.

And following the fall of the US stock market in 1929, the problem not only remained in New York, but moved to almost every country in the world as a domino effect.

after the civil war, and with the termination of slavery, the south was faced with a big problem; what was supposed to happen and how they were supposed to deal with the freedom and the rights that black people and freed slaves had gained as a result of the north defeating the south and forcing the end of slavery. first, most, if not all, of the workforce of the south came from slaves and they did not have an option to replace the loss of said workforce. second, particularly in the south, people were convinced that black people were lesser, less intelligent, less capable and less smart than whites. this posed a huge problem for them. also, southerners were faced with another issue; freed slaves now had a say in how their lives would be lived and the right to politically choose the way they would be governed. people in the south did not want to accept this, none of this and this opposition and the conflicts that arose from it, not to mention the afereffects of the war, forced the congress of the time to enact and enforce the reconstruction plans that had been proposed by president andrew johnson.
