Last Friday, we visited the Black Heritage Trail, which is a path in Boston, Massachusetts, winding through the Beacon Hill neighborhood and sites important in American black history. In 1783, Massachusetts became the first U.S. state to declare slavery illegal — mostly out of gratitude for black participation in the Revolutionary War . Subsequently, a sizable community of free blacks and escaped slaves developed in Boston, settling on the north face of Beacon Hill, and in the North End. Boston was long considered a desirable destination for southern black slaves escaping slavery via the Underground Railroad. Though the trip was very hot and tired, but we still made a very serious presentation.
