Workers organized strikes and unions to demand better treatment and rights. Key events, such as the Haymarket Affair (1886), highlighted labor struggles and led to reforms. Unions like the Knights of Labor and the American Federation of Labor (AFL) played crucial roles in advocating for workers’ rights. The movement pushed for policies like the 8-hour workday, workers’ compensation, and child labor laws. These efforts laid the groundwork for modern labor protections and continue to influence labor rights globally.
7.4 The Rise of Socialism
Socialism emerged as a response to the inequalities and exploitation of industrialization, advocating for collective ownership of the means of production. Karl Marx and Friedrich Engels, influenced by Enlightenment ideas, published The Communist Manifesto (1848), critiquing capitalism and proposing a classless society. Socialist movements gained momentum in Europe and beyond, inspiring labor unions and political parties. The idea of redistributing wealth and promoting social equality resonated with workers facing harsh industrial conditions.
