One of the early posts on this blog related to this letter "To the inhabitants of Bridgewater, Massachusetts, New England, America from the residents of Bridgewater, Somersetshire, England" regarding the abolition of slavery.
Recently, these two Bridgewaters once again came together in a joint Black Lives Matter protest
The event was covered by the Bridgwater (no "e") Westover Web.
I often see things that indicate that Massachusetts was the first state to abolish slavery in the United States, but rarely is it mentioned that it was the first state to legalize it as well. More information about the history of slavery in the Bay State can be found here.
