Answer: They are heads of executive departments.
Explanation:
They are appointed by the president but must be approved by the Senate. The Cabinet includes the Vice President, and has 15 different departments such as Health and Human services and Education.
Similarities--whites were in the dominant group in each region. Violence was common to exert power over the minority racial group to include lynchings. Voting and citizenship restrictions were also in place against the minority groups.
Differences--the targeted group in the South were blacks and in the West were blacks but also the Chinese population. In the South, racial order was the motivation for much of the racial conflict. In the West, job competition was the basis for much of the racial conflict.
We have to remember that there was a big difference between the treaties themselves and the paper documents that European-Americans used to record those treaties. For many Native Americans, a treaty was an oral agreement between governments. It was methodically memorized and often sealed with an exchange of gifts. In the eastern part of North America, wampum belts (which were shells strung together to create images) served as official records of these treaties, and were draped over a speaker's body when the treaty was being recited later on, much as Europeans might read aloud the text of a written agreement between two European countries.
For Natives, the oral agreement, along with these wampum belts, WERE the treaty, and the paper document they signed was just some odd European habit that they often simply tolerated. Many of the Native leaders who signed these treaties could not read what they were signing, and even if they could they did not recognize the documents as being the official record of what was agreed on.
