Even superheroes need a network: Harriet Tubman and the Rise of Insurgency in the New York State Underground Railroad

We analyze historical data to conduct an exploratory structural investigation into the process that Harriet Tubman used to free her family and friends as a member of the New York State Underground Railroad (UGRR). We suggest that she accomplished this feat because of her ability to rely on embedded (Granovetter 1985; Uzzi 1996) network contacts that allowed her to bridge structural holes (Burt 1992) and link with people with whom she was not previously linked (Lin et al., 2001). We conclude by discussing the importance of network analysis for providing empirical meaning to historical events and episodes.
