There were several different factors that caused the US to become a part of the imperialist movement, including:
1) Industrialization- The invention of technologies that allowed for the mass production of goods allowed businesses to make more of their products than ever before. Due to their increased ability to make large sums of goods, these individuals wanted the US to expand their global influence so that they may have new consumers to sell their products too.
2) Social Darwinism- This idea revolves around the concept of the "survival of the fittest." Many Americans felt that the US was a superior society that should spread its ideas and influence in order to help less civilized countries/territories.
I believe it was because both blacks and whites were moving west to the cities to find jobs.
hope i helped :)
Born on the island of Corsica, Napoleon rapidly rose through the ranks of the military during the French Revolution (1789-1799). After seizing political power in France in a 1799 coup d'état, he crowned himself emperor in 1804. Shrewd, ambitious and a skilled military strategist, Napoleon successfully waged war against various coalitions of European nations and expanded his empire. However, after a disastrous French invasion of Russia in 1812, Napoleon abdicated the throne two years later and was exiled to the island of Elba. In 1815, he briefly returned to power in his Hundred Days campaign. After a crushing defeat at the Battle of Waterloo, he abdicated once again and was exiled to the remote island of Saint Helena, where he died at 51.
