Harriet Tubman stands as one of the most influential leaders in the history of the United States. Her leadership did not rely on official titles, wealth, or political power. Instead, it was built on courage, moral conviction, and action. While she is best known for her role in the Underground Railroad, her leadership extended to the Civil War and the women’s suffrage movement. This article critically examines Harriet Tubman’s leadership by analyzing its moral foundation, strategic nature, and long-term impact on abolition and women’s rights. Drawing on historical criticism, Black feminist theory, and leadership studies, the study examines Tubman’s strategies of mobilization, her use of covert communication, and her ethical commitment to communal liberation. Through qualitative textual analysis of primary narratives and secondary scholarship, this paper demonstrates that Tubman’s leadership constituted a radical, embodied, and non-institutional model of activism that challenged dominant patriarchal and racial paradigms. By situating Tubman within the broader continuum of Black women’s political resistance, the study re-theorizes her role as a proto-Black feminist leader whose praxis continues to inform contemporary discourses on leadership, agency, and social justice.
