The Knights of Labor was founded in the United States in 1869. Eventually over 700,000 workers joined the Knights.

The American Federation of Labor (AFL) was founded by Samuel Gompers. By 1904, AFL-affiliated unions had a membership of over 1.4 million nationwide. Under Gompers’s leadership, the AFL advocated an approach known as “business” or “pure and simple” unionism, which emphasized collective bargaining to reach its goals. Demands were centered around improvements to the immediate work environment, like better wages, hours and working conditions.

In France, Germany, and other European countries, socialist parties and anarchists played a prominent role in forming and building up trade unions, especially from the 1870s onwards. This stood in contrast to the British experience, where moderate New Model Unions dominated the union movement from the mid-nineteenth century and where trade unionism was stronger than the political labor movement until the formation and growth of the Labour Party in the early years of the twentieth century.”
