named forSuffolk, England

Suffolk County ( ) is located in the Commonwealth of Massachusetts, in the United States. As of the 2020 census, the population was 797,936, making it the fourth-most populous county in Massachusetts. The county comprises the cities of Boston, Chelsea, and Revere, and the town of Winthrop. The traditional county seat is Boston, the state capital and the largest city in Massachusetts. The county government was abolished in 1999, resulting in Suffolk County now functioning only as an administrative subdivision of state government and a set of communities grouped together for some statistical purposes. Suffolk County is located at the core of the Boston-Cambridge-Newton, MA-NH Metropolitan Statistical Area as well as the greater Boston-Worcester-Providence, MA-RI-NH-CT Combined Statistical Area.

History

Old Suffolk County Courthouse 1810–1841

The county was created by the Massachusetts General Court on May 10, 1643, when it was ordered "that the whole plantation within this jurisdiction be divided into four shires". Suffolk initially contained Boston, Roxbury, Dorchester, Dedham, Braintree, Weymouth, Hingham and Hull. The county was named after Suffolk, England, which means "southern folk."

In 1731, the extreme western portions of Suffolk County, which included Mendon and Uxbridge, were split off to become part of Worcester County. In 1793, most of the original Suffolk County split off and became Norfolk County, leaving only Boston, Chelsea, Hingham, and Hull in Suffolk. Hingham and Hull would leave Suffolk County and join Plymouth County in 1803. Revere was set off from Chelsea and incorporated in 1846 and Winthrop was set off from Revere and incorporated in 1852. In the late 19th century and early 20th century, Boston annexed several adjacent cities and towns including Hyde Park, Roxbury, West Roxbury, and Dorchester from Norfolk County and Charlestown and Brighton from Middlesex County, resulting in an enlargement of Suffolk County.

During the early 20th century, County government functions were absorbed by the City of Boston, with Boston City Council becoming the de-facto County Commission, and the City Treasurer similarly becoming the County Treasurer, albeit said government was not formally abolished until 1999.

Government and politics

Like an increasing number of Massachusetts counties, Suffolk County exists today only as a historical geographic region, and has no county government. All former county functions were assumed by state agencies in 1999. The sheriff, district attorney, and some other regional officials with specific duties are still elected locally to perform duties within the county region, but there is no county council, executives or commissioners. Prior to the abolition of county government, the authority of the Suffolk County Commission had for many years been exercised by the Boston City Council, even though three communities in the county are not part of the city. However, communities are now granted the right to form their own regional compacts for sharing services.

Politically speaking, Suffolk County supports the Democratic Party overwhelmingly. No Republican presidential candidate has won there since Calvin Coolidge in 1924. In 2012 Barack Obama received 77.4% of the vote, compared to 20.8% for former governor of Massachusetts Mitt Romney. In the 2014 gubernatorial election, Martha Coakley carried the county by a 32.4% margin, while losing the election statewide by 48.4 to 46.5%. In 2020, Joe Biden won the county by the largest margin of any presidential candidate since Lyndon B. Johnson in 1964, and was the first candidate since then to win more than 80% of the vote in the county.

Sheriff's department

The Suffolk County Sheriff's Department's primary responsibility is oversight of the Nashua Street Jail and the South Bay House of Correction. These were built in the 1990s to replace the historic Charles Street Jail and Deer Island Prison, respectively. The Suffolk County Sheriff's Department was among those named in a 2020 WBUR report about the neglect of inmates with medical conditions in Massachusetts prisons leading to their deaths.

Several notable figures in Massachusetts history were once the sheriff of Suffolk County:

  • Joseph Hall (1818–1825)
  • Charles Pinckney Sumner (1825–1839)
  • John M. Clark (1855–1883)
  • John A. Keliher (1917–1938)
  • John F. Dowd (1938–1939)
  • Frederick R. Sullivan (1939–1968)
  • John W. Sears (1968–1969)
  • Thomas S. Eisenstadt (1969–1977)
  • Dennis J. Kearney (1977–1987)
  • Robert Rufo (1987–1996)
  • Andrea Cabral (2002–2013)
  • Steven W. Tompkins (2013–present)
