Essex County is a county in the northeastern part of the U.S. state of Massachusetts. At the 2020 census, the total population was 809,829, making it the third-most populous county in the state, and the seventy-eighth-most populous in the country. It is part of the Greater Boston area (the Boston–Cambridge–Newton, MA–NH Metropolitan Statistical Area). The largest city in Essex County is Lynn. The county was named after the English county of Essex. It has two traditional county seats: Salem and Lawrence. Prior to the dissolution of the county government in 1999, Salem had jurisdiction over the Southern Essex District, and Lawrence had jurisdiction over the Northern Essex District, but currently these cities do not function as seats of government. However, the county and the districts remain as administrative regions recognized by various governmental agencies, which gathered vital statistics or disposed of judicial case loads under these geographic subdivisions, and are required to keep the records based on them. The county has been designated the Essex National Heritage Area by the National Park Service.

History

Printed in 1812, this political cartoon illustrates the electoral districts drawn by the Massachusetts legislature to favor the incumbent Democratic-Republican party candidates of Governor Elbridge Gerry over the Federalists, from which the term gerrymander is derived. The cartoon depicts the bizarre shape of a district in Essex County as a "Gerry-Mander, A new species of Monster, (...) that (...) belongs to the Salamander tribe (...)".

The county was created by the General Court of the Massachusetts Bay Colony on May 10, 1643, when it was ordered "that the whole plantation within this jurisdiction be divided into four sheires". Named after the county in England, Essex then comprised the towns of Salem, Lynn, Wenham, Ipswich, Rowley, Newbury, Gloucester and Andover. In 1680, Haverhill, Amesbury and Salisbury, located north of the Merrimack River, were annexed to Essex County. These communities had been part of Massachusetts' colonial-era Norfolk County (1643–1680). The remaining four towns within "Old" Norfolk County, which included Exeter and what is now Portsmouth, were transferred to the Province of New Hampshire. The Massachusetts-based settlements were then subdivided over the centuries to produce Essex County's modern composition of cities and towns.

Essex County is where Elbridge Gerry (who was born and raised in Marblehead) created a legislative district in 1812 that gave rise to the word gerrymandering.

Due to a confluence of floods, hurricanes, and severe winter storms, Essex County has had more disaster declarations than most other U.S. counties, from 1964 to 2016.

Law and government

From the founding of the Republican Party until the New Deal, Essex County was a Republican stronghold in presidential elections. Since 1936, it has trended Democratic, with Dwight Eisenhower in 1952 and 1956 and Ronald Reagan in 1980 and 1984 being the only Republicans to carry the county since.

Like several other Massachusetts counties, Essex 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 (currently Kevin Coppinger), district attorney (currently Paul Tucker), 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, commissioner, or county employees. Communities are now granted the right to form their own regional compacts for sharing services.

On November 12, 1996, Essex National Heritage Area (ENHA) was authorized by Congress. The heritage area consists of all of Essex County, MA a 500-square-mile (1,300 km²) area between the Atlantic Coast and the Merrimack Valley. The area includes 34 cities and towns; two National Historic Sites (Salem Maritime National Historic Site and Saugus Iron Works National Historic Site); and thousands of historic sites and districts that illuminate colonial settlement, the development of the shoe and textile industries, and the growth and decline of the maritime industries, including fishing, privateering, and the China trade. The Essex National Heritage Area is one of 49 heritage areas designated by Congress, affiliated with the National Park Service.

The Essex National Heritage Commission is a non-profit organization chartered to promote tourism and cultural awareness of the area, connecting people to the places of Essex County, MA. The commission's mission is to promote and preserve the historic, cultural and natural resources of the ENHA by rallying community support around saving the character of the area. This is accomplished through the commission's projects and programs, which include Partnership Grant Program, Explorers membership program, photo safaris, and the annual September weekend event Trails & Sails, as well as other important regional partnership building projects like the Essex Heritage Scenic Byway, and the Border to Boston trail.
