Harriet Tubman becomes Underground Railroad conductor

Background. The Underground Railroad was an organized network of secret routes and safe houses for fugitive slaves. It began organizing in the 1780s among abolitionist societies in the North. By 1850, approximately 100,000 slaves had escaped via this network. The Fugitive Slave Act of 1850, passed after the Mexican-American War, made aiding fleeing enslaved people a criminal offense in free states, altering the nature of escape routes.

Tubman's Role. Harriet Tubman made approximately 13 missions to rescue 70 enslaved people using the Underground Railroad network. After escaping slavery in 1849, she returned to Maryland to rescue family. Following the 1850 Act, she guided escapees farther north into British North America. The legacy row's 'official conductor' framing is anachronistic, as the network had no official roles; this is a correction note rather than a sourced fact.

Impact of the Act. The Fugitive Slave Act of 1850 forced law enforcement to assist in capturing escaped slaves, even in free states, and heavily punished abetting escape. This led to increased flight to Canada, where many fugitives considered their final destination. Between 1850 and 1860, half of the estimated 30,000 to 40,000 fugitives who settled in Canada arrived.
