The Commonwealth of Massachusetts ( ) is a state located in the New England region of the northeastern United States. It borders Rhode Island and Connecticut to the south, New York to the west, and Vermont and New Hampshire to the north. Most of its population of 6.4 million live in the Boston metropolitan area. The eastern half of this relatively small state is mostly urban and suburban, while Western Massachusetts is mostly rural. Massachusetts is the most populous of the six New England states. It ranks third among U.S. states in overall population density and fourth in GDP per capita.

Massachusetts has been significant throughout American history. Plymouth was the second permanent English settlement in North America. Many of Massachusetts' towns were founded by colonists from England in the 1620s and 1630s. During the eighteenth century, Boston became known as the "Cradle of Liberty" for the ferment there which led to the American Revolution and the independence of the United States from Great Britain. In the nineteenth century, Massachusetts was the first U.S. state to abolish slavery. Also, it was a center of the temperance movement and abolitionist activity preceding the American Civil War. In 2004, Massachusetts became the first U.S. state to legally recognize same-sex marriage. The state has contributed many prominent politicians to national service, including the Adams family and, more recently, the Kennedy family.

Originally dependent on agriculture and trade with Europe, Massachusetts was transformed into a manufacturing center during the Industrial Revolution. During the first half of the twentieth century, the migration of factories to lower-wage Southern states caused economic stagnation. The economy of Massachusetts revived after World War II, and began thriving during the 1990s. The state is a leader in higher education, health care, and high technology.

Name

The Massachusetts Bay Colony was named after the indigenous population, the Massachuset, whose name can be segmented as mass-adchu-s-et, where mass- is "large", -adchu- is "hill", -s- is a diminutive suffix meaning "small", and -et is a locative suffix, identifying a place. It has been translated as "near the great hill," "by the blue hills" "at the little big hill," or "at the range of hills," referring to the Blue Hills, or in particular, Great Blue Hill, located on the boundary of Milton and Canton, to the southwest of Boston.Salwen, Bert, 1978.
