Answer:
The correct answer to the question: In 1869, what labor union formed and admitted all workers regardless of race, position, or skill, would be, the Knights of Labor.
Explanation:
Many were the labor unions that in the 19th century helped fight for the rights of workers. However, none was as iconic as the Knights of Labor, also known as the Noble and Holy Order of the Knights of Labor, which was established in the 1800s. One of the principles under which this group worked was, to promote cultural and social welfare, reject socialism and anarchism and demand certain benefits for the workers in the United States. In essence, unlike other unions, the Knights of Labor allowed people to join in regardless of their race, their position, or skill; what did matter is the person´s productivity in society. Other than that, almost anyone was allowed in.
