Prior to 1909, Boston's legislative body consisted of an eight-member Board of Aldermen and a Common Council made up of three representatives from each of the 25 wards in the city. When the Boston City Charter was rewritten in 1909, the Board of Aldermen and the Common Council were replaced by a nine-member City Council. All nine councillors were elected at-large for terms lasting two years. The new charter also gave the Mayor the power to veto all acts of the City Council. The first council meeting as a unicameral body occurred on February 7, 1910.
