Settlers and tribes both had effects on each other. On many trails headed west, settlers traveled in fear of attack from tribes who would rob or kill members of caravans.

If you need a commentary, here it is.

White American settlers who traveled to the west met fierce opposition from the Native American Natives of the region. The Native American Indians thought that those lands were theirs. The land belonged to them and had been inherited by their ancestors. That is why they defended their territories.

On the other hand, white settlers were interested in occupying those territories to settle in and exploit the many natural resources and raw materials of the region.

So as your statement reads, settlers and tribes both had effects on each other. On many trails headed west, settlers traveled in fear of attack from tribes who would rob or kill members of caravans. Tribes would attack stagecoaches and wagons that traveled across their lands. On the other hand, settlers constantly encroached on tribes' lands.

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]
