Appeasement was used by Europe before WWII in hopes that Hitler would get what he wanted (Which he claimed was just some more "Living space") and stop. The basically let him invade and take over a bunch of territories. This allowed him to gain a lot more power and land and let him invade and take over places before they could fight back. Appeasement let Hitler do what he wanted without immediate consequence.
The correct answer is "War broke out when white settlers pressured the government to take the land from American Indians. "
An example of this would be the Wounded Knee Massacre. This was a result of the discovery of gold on the Lakota Pine Ridge reservation in South Dakota. US citizens wanted to take this land from American Indians, as gold was a valuable commodity that could be sold to make a huge profit. Along with this, the American economy still relied on the gold standard.
This resulted in an armed conflict between members of the US military and the Lakota tribe.
