The Aztecs and the Mayans were two ancient societies in Meso America. The Mayan civilization goes back to about 1800-2000 BC and was in decline when the Spaniards arrived whereas the Aztecs were a much younger civilization that was at its peak when Cortez arrived. The Aztecs were located mostly in what is now Mexico whereas the Mayans were more in what is now Guatemala and Honduras. Both the Aztecs and Mayans believed in human sacrifice but the Aztecs did this much more than the Mayans. While the Aztecs layed out their cities according to celestial observances, the Mayans were more scientific and developed a calendar very similar to our modern calendar. The Aztecs had one supreme ruler whereas the Mayans had many city states like Uxmal in Guatemala and Copan in Honduras with local rulers.
The "affordability" of the automobile in the 1950s changed American culture.
Affordability is in quotes because the automobile manufacturers did something tricky. They got the US government to pay for the building and maintenance of roads.
So, unlike the train system where the train companies have to build and maintain tracks, the auto makers only had to make the cars.
This reshaped our country, allowing roads and cars to become the primary means of transportation in the country. In turn, people could then live outside of cities allowing suburbs to be created and fast food restaurants to be invented for people in the car on the go.
The effect of foreign conflict on Americans support would be the War of 1812 where British captured Washington, D.C. and burned our White House, and also U.S. forces turn back a British attack on Baltimore. The good thing that came out of the conflict was gaining our "Star Spangled Banner" from Francis Scott Key.
