First a part of Dunstable, Massachusetts, then settled as West Hollis, New Hampshire, the town was granted in 1769 as "Raby". New Hampshire GovernorJohn Wentworth named it after his cousin, the 4th Earl of Strafford and Baron of Raby Castle. The town was renamed in 1798 at the suggestion of a leading citizen in town originally from Brookline, Massachusetts. By 1859, when the population was 718, there were eight sawmills and one gristmill, as well as a sash and blind shop. In the earlier days of the town, Brookline was known throughout southern New Hampshire for producing lumber, charcoal and casks. The Boston and Maine Railroad eventually branched into Brookline in 1892. The train station that served Brookline during the railroad's tenure in the town has since been renovated into a private residential home. A large fraction of the area that was once railroad track is now New Hampshire Route 13. The town received national attention in 1997, when people participating in the traditional ringing of the Congregational Church bell at midnight on the Fourth of July were arrested. Several prominent members of the community were among those arrested, including Road Agent Clarence Farwell and his wife. The incident led to an investigation of the Brookline police department after questions of excessive force were raised following the arrests.
