How did the western expansion impact the relationship between the American government and Native Americans

It contributed to the hostility of American government and Native Americans.

Explanation:

Because of the western Expansion, the influx of immigrants that come to Western front far surpassed that the American government initially predicted. The government did not have enough land to accommodate these immigrants.

To handle this, American government decided to take the ancestral lands that previously belonged to the native American and force them to live in reservation. This caused series of wars/conflicts between Native Americans and the American government.

when world war i broke out across europe in 1914, president woodrow wilson proclaimed the united states would remain neutral, and many americans supported this policy of nonintervention. however, public opinion about neutrality started to change after the sinking of the british ocean liner lusitania by a german u-boat in 1915; almost 2,000 people perished, including 128 americans. along with news of the zimmerman telegram threatening an alliance between germany and mexico, wilson asked congress for a declaration of war against germany. the u.s. officially entered the conflict on april 6, 1917.
