The June Riot: Neal Dow was a vehement advocate of alcohol prohibition. During his tenure as mayor of Portland, he enforced the Maine Law zealously, which made him increasingly unpopular in some circles. In June of 1855, Dow paid for a shipment of liquor that had been sold to the city for medicinal purposes and stored the liquor in the basement of City Hall. Legally, the only person who could purchase medicinal liquor for the city was an agent authorized to do so. When the city's residents heard of the shipment, they crowded around City Hall, insisting that Dow had broken the law himself and should be punished. The crowd became unruly, Dow called in the police and the city militia, and ordered them to fire on the crowd. Seven rioters were wounded and one was killed.
