The main point of this excerpt is that African-Americans were not considered US citizens.
In the Supreme Court case Dred Scott vs. Sandford, Scott is suing for his freedom from slavery. This is because his master brought him to the Wisconsin territory, a territory where slavery was outlawed.
However, the Supreme Court ruled against him. The reason why they ruled against him is based on the excerpt above. The Declaration of Independence did not make it blatantly clear that slaves were considered citizens. Since they were not considered citizens, they had no legal rights that slave owners had to respect.
Answer:
The correct answer is: The federal government sent the troops to restore peace and to break the impasses.
Explanation:
The Labor movement in the U.S. was founded to protect the interests and rights of workers. Its main goal was to prevent child labor, provide health benefits, and help to injured or retired workers. During these strikes, the federal government sided with businessmen and factory owners instead of supporting unions and strikers. The strikes took place at West Virginia.
When the strikes began, the government sent militias and federal troops to put down the strikes, so the union collapsed after two months.
