Why/how did slavery begin in the United States?
Delicious77 [7]

Answer:

first as a mixture of indentured slavery, African chattel slavery, and native American slavery for economic gain in the Southern colonies.

Explanation:

The Southern colonies, including in the West Indies, had mainly focused on the production of cash crops and plantation agriculture. However, this took a lot of labor, including in dangerous working environments. Indentured servants, often times immigrants from Ireland, were a risky investment, and often died. New diseases from the old world killed off much of the native American population, not to mention they knew the land and had places to escape from slavery to. African chattel slavery had two main benefits: 1) they came from Africa in large quantities (with much immunity due to the longer history of European interaction) and typically had no where to go, making them available, and 2) their children were also born into slavery, meaning there were essentially, in the eyes of masters, and endless "supply" of slaves. Even after new slave importation from Africa was banned, the children of slaves remained and continued on. This economic benefit that slaves carried continued far after the American Revolution in the south, especially after the creation of the cotton gin during the market revolution, as well as western expansion, that made slavery even more practical than it had previously been.

What did nativists groups believe would happen if European ethnic groups continued to immigrate to the United States after World
zlopas [31]

Answer:

<h3>The Anglo ideal would disappear.</h3>

Explanation:

After World War I, nativists groups in U.S started to fear that if European ethnic groups continued to immigrate to the United States after, their anglo ideal and culture would disappear.

With increase in immigration from Europe after the end the World War I, the native-born Americans of European lineage felt threatened with the multiplicity of European languages, cultures, and religions increasing in the U.S.

In order to preserve their own culture and language, the nativists started numerous protests for new immigration policies. Subsequently,the Emergency Immigration Act of 1921 was introduced. For the first time, it put certain restrictions on European immigration in U.S.

The National Origins Act of 1924 was further introduced to restrict southern and eastern European immigrants. The political unrest in Russia after the end of the first World War led many eastern Europeans to migrate to U.S and other countries.
