Question

What was the name of the first successful national labor organization in the united states that offered membership to all workers regardless of occupation, education, gender or race?

Answer 1

This labor union was called the knights of labor. They were the second national labor organization and were created in 1869 as a secret society. They opened up for public membership in 1881. However, they lost a lot of members after the mid-1880's due to their involvement in violent strikes and fights between the skilled and unskilled members.
