History of Suffolk County
Suffolk County was created a long time ago, on May 10, 1643. This happened when the leaders of the Massachusetts Bay Colony decided to divide the area into four main parts, called "shires."
When it was first formed, Suffolk County included Boston and several other towns. These towns were Roxbury, Dorchester, Dedham, Braintree, Weymouth, and Hingham. The county was named after Suffolk, a place in England. The name "Suffolk" means "southern folk."
Over the years, the borders of Suffolk County changed. In 1731, some western parts of the county, like Mendon and Uxbridge, became part of Worcester County. Later, in 1793, most of the original Suffolk County split off. These areas became Norfolk County. Only Boston, Chelsea, Hingham, and Hull stayed in Suffolk County.
In 1803, Hingham and Hull also left Suffolk County. They joined Plymouth County instead. Revere became its own town in 1846, separating from Chelsea. Winthrop became a town in 1852, separating from Revere.
In the late 1800s and early 1900s, Boston grew bigger. It added several nearby cities and towns. These included Hyde Park, Roxbury, West Roxbury, and Dorchester from Norfolk County. It also added Charlestown and Brighton from Middlesex County. This made Suffolk County larger again.
In the early 1900s, the City of Boston started taking over many of the county's jobs. The Boston City Council began acting like the county's main group. The City Treasurer also took on the role of County Treasurer. The county government was officially ended in 1999.
