Two weeks later, the US army went to Wounded Knee, South Dakota, and killed one hundred fifth Lakota men, women, and children.
The USA has always been a country with a lot of immigration. After the Civil War, many Americans left their homes in the east and went to western states, where they could buy cheap farmland. Another twelve million immigrants, many from the south and west of Europe, arrived between 1892 and 1924.
People wanted to live " the American Dream", the idea that those who work hard could fin success and get rich. In 1850, there were fewer than twenty millionaires in the USA, but by 1900,there were forty thousand! The 1920s were a time of wild spending and a lot of fun for many American.
