How did social democrats disagree with socialist revolutionaries?

Social democrats disagreed with socialist revolutionaries primarily on the means and timing of achieving socialism. While socialist revolutionaries advocated for immediate, often violent uprisings to overthrow capitalist systems, social democrats favored a gradual approach, emphasizing electoral politics and reform within existing political structures. They believed in working through democratic institutions to achieve social change, prioritizing stability and broad-based support over radical upheaval. This fundamental philosophical divide shaped their strategies and goals throughout the early 20th century.
