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

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

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)
