The American Federation of Labor is a national labour movement in the United States that was founded in 1886. The aim of the American Federation of Labor is to improve the lives of working people.
The statements that it was led by Uriah Stephens, called for equal pay for women and worker ownership of businesses, and welcomed common factory laborers into its ranks are wrong.
The American Federation of Labor simply ,"focused on the economic advancement of its members".
This is a little open for interpretation, but I would generally say that the best answer is that Josip Broz Tito was a very powerful leader, who kept the republics and the different groups together.
For example, we can see this from the fact that the first conflict happened in 1981: one year after his death ( a protest of Kosovans who demanded autonomy).
