The original inhabitants of the islands were Wampanoag, who had several villages. Political jurisdiction over the lands were granted by the English monarchy in overlapping claims to two different British nobles, from which Massachusetts Bay Company settler Thomas Mayhew purchased them in 1641. Mayhew established a colony in his new domain, carefully purchasing land ownership rights from the native inhabitants, and maintaining native governments to continue unimpeded. In 1665, Mayhew's lands were included in a grant to the Duke of York. In 1671, a settlement was arranged, allowing Mayhew to continue to rule while placing his territory under the jurisdiction of the Province of New York.
Dukes County was thus established as Dukes County, New York, on November 1, 1683, and included all of Mayhew's lands – Martha's Vineyard, Nantucket, and the Elizabeth Islands. The county was transferred to Massachusetts on October 7, 1691, and at the same time Nantucket Island was split into the separate Nantucket County, Massachusetts. The 1695 incorporation statute created a county "by the name of Dukes County," as opposed to the standard form "the county of Dukes" which is the reason for the redundancy in the formal name, "County of Dukes County".
According to the U.S. Census Bureau, the county has a total area of 491 square miles (1,270 km2), of which 103 square miles (270 km2) is land and 388 square miles (1,000 km2) (79%) is water. It is the third-smallest county by land area.

It is the 58th largest island in the United States, with a land area of about 96 square miles (250 km2), and the third-largest on the East Coast of the United States, after Long Island and Mount Desert Island. Martha's Vineyard constitutes the bulk of Dukes County, Massachusetts, which also includes the Elizabeth Islands and the island of Nomans Land.
The Vineyard was home to one of the earliest known deaf communities in the United States; consequently, a special sign language, Martha's Vineyard Sign Language, was developed on the island. The 2010 census reported a year-round population of 16,535 residents, although the summer population can swell to more than 100,000 people. About 56 percent of the Vineyard's 14,621 homes are seasonally occupied.Martha's Vineyard is primarily known as a summer colony, and it is accessible only by boat and air. However, its year-round population has considerably increased since the 1960s.

The population of the Vineyard was 14,901 in the 2000 Census and was estimated at 15,582 in 2004. (Dukes County was 14,987 in 2000 and 15,669 in 2004).
