Pittsfield's 1791 Bylaw Mentions Baseball
On March 15, 1791, the town of Pittsfield, Massachusetts approved a bylaw that prohibited playing baseball within eighty yards of the town meeting house. The point of the rule was practical: officials wanted to protect windows and maintain order around the civic center. For baseball history, the line stands as the earliest known written U.S. reference to baseball.
The bylaw does not describe rules, teams, or scoring. It simply assumes people already knew the game. That single detail tells us baseball was not invented overnight by one person in one place. It was already familiar enough to require regulation by local government.
Historians still debate exactly how games played in the 1790s connect to the modern sport. Early "base ball" appeared in multiple local forms, and many rules were informal. Even so, Pittsfield's record remains the clearest starting marker for baseball's documented U.S. footprint.
