Josiah Henson’s Life in Montgomery County

Josiah Henson Museum & Park is the former plantation property of Isaac Riley where Reverend Josiah Henson was enslaved. This park is a historic resource of local, state, national and international significance because of its association with Reverend Henson, whose 1849 autobiography, The Life of Josiah Henson, Formerly a Slave, Now an Inhabitant of Canada inspired Harriet Beecher Stowe’s landmark novel, Uncle Tom’s Cabin. The Park contains the historic Riley/Bolten House (ca. 1800-1815) and its attached log kitchen (ca.1850-51). Ongoing archaeological excavations seek to find where Josiah Henson may have lived on the site.

The Josiah Henson Museum & Park is part of the National Park Service National Underground Railroad Network to Freedom program.

Henson eventually escaped to Canada in 1830, where he helped established Dawn Settlement, a community inhabited by former American slaves, continued his work in the Methodist ministry, and became an international speaker and abolitionist. Henson led 118 people from enslavement in the United States to freedom in Canada as a conductor on the Underground Railroad.

Many of Henson’s experiences of life enslaved on the Riley plantation are vividly depicted in his autobiography and later recreated in Stowe’s fictional novel, Uncle Tom’s Cabin. The impact of Stowe’s novel should not be underestimated. Published in 1852, it broke all sales records of the time and sold more than half a million copies by 1857. The book inspired and inflamed the abolitionist movement in the mid-nineteenth century, and many believe the novel helped to propel the American Civil War.

Because of the historical associations of the Josiah Henson Museum & Park, it is among few properties in Montgomery County that conjures up images of slavery and the experience of the enslaved. The museum strives to accurately portray Henson’s life and the Maryland enslaved experience as well as to explore the impact of Stowe’s novel. Josiah Henson was a freedom fighter. His legacy is an important part of African American history.

Museum & Exhibits

You will begin your time in the visitor center where you will find indoor and outdoor interpretive exhibits, an eclectic museum shop, and an 80-person multipurpose theater featuring the 12-minute orientation film, My Name is Josiah Henson.

Continue to the historic Riley/Bolten House to explore the life of Josiah Henson from enslavement endured on the Riley plantation, to freedom in Dresden, Ontario as told in his own words-dramatically illustrated by artist Kyle Baker. While Henson’s story ends, the legacy of slavery does not. As such, we must address how the effects of the enslavement of African Americans still ripple through our society today.

My hope is that people will come to understand who the Rev. Josiah Henson truly was, a man of tremendous strength, intelligence, loyalty, and of great faith. That individuals will walk away understanding the current use of “Uncle Tom” as a derogatory term is not at all who the real Uncle Tom was. The real Uncle Tom was a Hero, a family man, a man who risked his life on countless occasions by helping others escape slavery. A man to be Proud of. This platform will help to change the current narrative with so many and teach upcoming generations of his life and the many contributions he made to the US and Canada.
