When one thinks of Black History, New Hampshire is not the first place to that comes to mind, but there actually is a lot of Black History in New Hampshire.
Portsmouth, NH for example was a major slavery port in the old days and they have recently added an excellent Black History Trail with historic markers.
The Portsmouth Black Heritage Trail, now under the umbrella of the Black Heritage Trail of New Hampshire, was founded in 1995 to preserve, celebrate and honor the history and culture of the African-American community in Portsmouth and the New Hampshire region. With distinctive bronze plaques that identify the community from its colonial-era African Burying Ground to the modern Civil Rights Movement, the Trail is proud to serve as a model across the country on what it means to raise public awareness and appreciation for a region not known for its Black history.
