Why did William Morris leave Henry Mayers Hyndman’s Social Democratic Federation?

William Morris left the Social Democratic Federation (SDF) primarily due to conflicts with the organization's leader, Henry Mayers Hyndman.1

Morris found Hyndman’s leadership style to be autocratic, which created friction within the group. Additionally, Hyndman’s difficult personality was known to antagonize many of his contemporaries, ultimately lessening his political effectiveness and driving key members away. Following these disagreements, Morris and other members broke away from the SDF to establish the Socialist League, an organization that operated independently with its own publication, The Commonweal.12
