The Aztec Empire was a civilization located in western South America (The Andes) And the Spanish invaded the Aztecs and annexed them.
Your answer would be D). Western Europe. During the 1600s and 1700s, people that were from Western Europe, mostly people from Great Britain, did not like the way the government worked, and they wanted to have more freedom. Because of that, they became colonists. Colonists are people that settle into a new land and form a colony, and that's what they did. They immigrated from Western Europe to the United States to have more freedom, because the government in Great Britain was very strict at that time. Also, there were a lot of pilgrims that wanted to freely practice their religion, but places in Western Europe didn't allow that, so they also immigrated to the United States so they could practice their religion without worrying about things stopping them. They immigrated to the United States, formed their own colony, and became independent from Great Britain.
Louisiana Purchase summary: The United States bought 828,000 square miles of land from France in 1803. The French controlled this region from 1699 until 1762 when it became Spanish property because France gave it to Spain as a present, since they were allies. But under Napoleon Bonaparte, France revived the aspirations to build an empire in North America so the territory was taken back in 1800. However, those big plans were not meant to be because Napoleon needed to concentrate on preparations for war with the British Empire and so the land was sold to the United States. The price was 15 million dollars.
The purchased territory included the whole of today’s Arkansas, Iowa, Missouri, Kansas, Oklahoma, and Nebraska, parts of Minnesota and Louisiana west of Mississippi River, including New Orleans, big parts of North and northeastern New Mexico, South Dakota, northern Texas, some parts of Wyoming, Montana, and Colorado as well as portions of Canadian provinces Alberta and Saskatchewan.
Thomas Jefferson was the American president at the time of the Louisiana Purchase. The United States initially wanted to buy only New Orleans and the land around it. The purchase met with the strong opposition in the States on account of being unconstitutional. Those accusations were accurate, at least to some extent. President Jefferson couldn’t deny that the Constitution of the United States did not provide for acquiring new territories but still he decided to proceed with the purchase since the removal of French presence in the region was such an important issue.
Guns. Lots of guns and transport for those guns. Also telecommunication from Mores Code.
