Delaware Counties

Delaware has three counties: New Castle, Kent, and Sussex, the fewest Counties of any US state. The origin of the county boundaries go back to former court districts. The powers of the counties' legislative bodies are limited to issues such as zoning and development.

Sussex County is a county located in the southern part of the state of Delaware, on the Delmarva Peninsula. Based on the 2010 census, the population was 197,145. Sussex County was created on August 8, 1673 as an Original County (originally named Whorekill or Hoarkill, renamed 1681 to Deale or New Deal, renamed to Sussex in 1682). The county seat is Georgetown.  The county was named by William Penn for the English county of Sussex, which was his home county.

The first European settlement in the state of Delaware was founded by the Dutch in 1631 near the present-day town of Lewes. However, Sussex County was not organized until 1683 under English colonial rule.

Sussex County is included in the Salisbury, MD-DE Metropolitan Statistical Area which encompasses much of central Delmarva.

Sussex County History


Between 10,000 and 14,000 years ago, archaeologists estimate that the first inhabitants of Sussex County, the southernmost county in Delaware, arrived. Native Americans in Sussex County called themselves by the various tribal names of the Algonquin Nation. The most prominent tribes in the area were the Leni Lenape and Nanticoke tribes. The people settled along the numerous bodies of water in the area where they were able to harvest fish, oysters, and other shellfish in the fall and winter. In the warmer months they planted crops, and hunted deer and other small mammals as larger game was not present in the area.

European Discovery

There is no universally agreed upon group known to be the first to settle in Sussex County. In the early years of exploration, from 1593 to 1630, many feel the Spanish or Portuguese were probably the first to see the Delaware River and the lands of present day Sussex County.

Henry Hudson, on his expedition for the Dutch West India Company, discovered the Delaware River in 1609. Attempting to following him, Samuel Argall, an English explorer, was blown off course in 1610 and landed in a strange bay that he named after the Governor of Virginia, Thomas West, Lord De La Warr.

In the first half of 1613, Cornelius Jacobsen Mey, a Dutch navigator, discovered and named both Cape May, New Jersey and Cape Henlopen, (originally Hindlopen) in the Delaware Bay. Later it was found that what May had named Henlopen, was actually Fenwick Island protruding into the Atlantic Ocean, and the name of the cape was moved to its present location just east of Lewes.

European Settlement

Sussex County, was the site of the first European settlement in Delaware, a trading post named Zwaanendael at the present site of Lewes in June 3, 1631. Dutch captain David Pietersen De Vries landed along the shores of the Delaware to establish a whaling colony in the mid-Atlantic of the New World. The colony only lasted until 1632, when De Vries left. Upon returning to Zwaanendael that December, he found the Indian tribes had killed his men and burned the colony. The Dutch then set about settling the area once again.

The original boundaries were undefined with boundary disputes between the family of William Penn, who claimed the county extended to Fenwick Island, and Charles Calvert, 5th Baron Baltimore, who claimed the county ended at Lewes with all the land south of that belonging to Somerset County[Sussex County, Delaware: USGenWeb Project]. Maryland and Pennsylvania both claimed the land between the 39th and 40th parallels according to the charters granted to each colony. The 'Three Lower Counties' (Delaware) along Delaware Bay moved into the Penn sphere of settlement, and later became the Delaware Colony, a satellite of Pennsylvania.

In 1732 the proprietary governor of Maryland, Charles Calvert, signed an agreement with William Penn's sons which drew a line somewhere in between, and also renounced the Calvert claim to Delaware. But later Lord Baltimore claimed that the document he signed did not contain the terms he had agreed to, and refused to put the agreement into effect. Beginning in the mid-1730s, violence erupted between settlers claiming various loyalties to Maryland and Pennsylvania. The border conflict between Pennsylvania and Maryland would be known as Cresap's War.

The issue was unresolved until the Crown intervened in 1760, ordering Frederick Calvert, 6th Baron Baltimore to accept the 1732 agreement. As part of the settlement, the Penns and Calverts commissioned the English team of Charles Mason and Jeremiah Dixon to survey the newly established boundaries between the Province of Pennsylvania, the Province of Maryland, Delaware Colony and parts of Colony and Old Dominion of Virginia.

Between 1763 and 1767, Charles Mason and Jeremiah Dixon surveyed the Mason-Dixon line settling Sussex County's western and southern borders. After Pennsylvania abolished slavery in 1781, the western part of this line and the Ohio River became a border between free and slave states, although Delaware remained a slave state.

In 1769 there was a movement started to move the county seat from Lewes to the area then known as Cross Roads, the present day site of Milton. The current county seat of Georgetown was settled upon on January 27, 1791 after residents in western Sussex County successfully petitioned the Delaware General Assembly to move the county seat to a central location as roads at the time made it too difficult to reach the county seat in Lewes. Georgetown was not a previously established town and on May 9, 1791, the 10 commissioners headed by President of the State Senate George Mitchell negotiated the purchase of 76 acres and Commissioner Rhodes Shankland began the survey by laying out "a spacious square of 100 yards each way." Eventually the Town was laid out in a circle one mile across, centered on the original square surveyed by Shankland and now listed on the National Register of Historic Places. Georgetown was named after Senate President George Mitchell.

Sussex County has been known by several names over the years including Susan County, Hoorenkill or Whorekill County as named by the Dutch prior to 1680 when Kent County broke off, Deale County from 1680 to 1682 after being taken over by the British under James Stuart, Duke of York prior to signing over to William Penn, and Durham County when claimed by the Lord's Baltimore during the boundary dispute with the Penn family


From the first Dutch settlers in the early 17th century to the present day, Sussex County has seen many visitors. Some of those visitors have stayed, farming the land, harvesting resources, working and calling this new land home. The largest, but historically least populous, county in the state of Delaware, Sussex County has had its share in the limelight of history. Below are some key dates in Sussex County and Delaware's history:
  • 1609 - Henry Hudson and his crew aboard the Half Moon enter the mouth of what will become known as Delaware Bay.
  • 1631 - Dutch established a trading post in what is present-day Lewes, calling the colony Zwaanendael, or "Valley of the Swans".
  • 1681-1682 - The King of England grants Pennsylvania and Delaware to William Penn, an English proprietor who names Delaware's southernmost county for his home county of Sussex in England. The land grant sets off years of disputes with the Calvert family of neighboring Maryland, who challenge the boundaries between Delaware and Maryland.
  • 1704 - Delaware, also known as the "Three Lower Colonies,"is established as its own government independent of Pennsylvania, though still under English rule.

  • 1768 to 1774 - English surveyors Charles Mason and Jeremiah Dixon survey the boundary of Delaware, beginning in Delmar, working their way north to Pennsylvania and then west for the boundary between Pennsylvania and Maryland; the survey formalizes the boundary, and thus brings an end the decades of dispute that began with the Penns and Calverts.
  • 1776 to 1783 - Revolutionary War.
  • 1787 - Delaware becomes the first state to ratify the US Constitution.
  • 1791 - Georgetown platted out and established as the new County seat; the County seat had been located at Lewes, but was relocated to a more central portion of the County.
  • 1813 - Lewes bombarded by the British during the War of 1812.
