In the decades after the Civil War, cities in the United States grew at an incredible rate. In
1860, only nine cities had a population of more than 100,000. By 1880 that number had
more than doubled to 20. Twenty years later in 1900, there were 38 cities with over 100,000
residents. By 1920, with 68 such cities, the country's urban population exceeded that of
rural areas for the first time in American history. New York City led the way with a
population of nearly 3,500,000 in 1900, but other cities like Chicago weren't far behind.
Over a 40 year period, Chicago's population grew from 100,000 to 1,700,000. This massive
growth was driven by three factors: immigration, migration and industrialization.

to show how quickly cities grew after 1860 due to immigration, migration and
industrialization
D

the first historical instance of china engaging in internationalism was during the han dynasty.[1] at the start of the han dynasty, the huns in the north were attacking the frontiers of han and trying to obtain riches. emperor wu of han wanted to gain an alliance with a country called dayuezhi so the two countries could join together and fight against the huns.[2] to obtain this alliance, emperor wu sent zhang qian to the west to establish economic and cultural connections.[2] history records that during the han dynasty there were four primary avenues of contact between china and europe. they included the northern land route, the central land route, the southern sea route, and the far southern sea route.[1] the most famous of these routes is the central land route, or the classical silk road, comprising a network of roads stretching from northwest china to the ports of syria and the black sea, which passed through the oasis of the turkestans and northern persia.[1] the silk road was significant for chinese emperors because it provided dominance over central asia by developing resources and provided new markets for the export of china's most valuable resources.[1]
