Early explorations of the Delaware coastline were made by the Spaniards and Portuguese in the sixteenth century, by Henry Hudson in 1609 under the auspices of the Dutch, by Samuel Argall in 1610, by Cornelius May in 1613, and by Cornelius Hendricksen in 1614.
The year 1681 marked the granting of the Province of Pennsylvania to William Penn by King Charles II and the arrival of Penn's agents on the Delaware River. They soon reported to the proprietor that the new province would be landlocked if the colonies on either side of the Delaware River or Bay were hostile. As a result of Penn's petition to the Crown for the land on the west side of the Delaware River and Bay below his province, the Duke of York in March 1682 conveyed, by deeds and leases now exhibited by the Delaware State Archives in the Hall of Records at Dover, the land included in the Counties of New Castle, St. Jones, and Deale. On October 27 of the same year, William Penn landed in America first at New Castle and there took possession from the Duke of York's agents as Proprietor of the lower Counties. On this occasion, the colonists subscribed an oath of allegiance to the new proprietor, and the first general assembly was held in the colony. The following year the three Lower Counties were annexed to the Province of Pennsylvania as territories with full privileges under Penn's famous "Frame of Government." Also in this year, the counties of St. Jones and Deale were renamed Kent and Sussex Counties respectively.
After 1682, a long dispute ensued between William Penn and Lord Baltimore of the Province of Maryland as to the exact dominion controlled by Penn on the lower Delaware.
An important stimulus to the recovery of the state's economy after the war was the invention in 1785 by Oliver Evans of Newport, Delaware, of automatic flour milling machinery, revolutionizing the industry.
In the following year, John Dickinson of Delaware presided over the Annapolis Convention, which called for the Federal Constitutional Convention, that met in Philadelphia the next year. When the new Constitution was submitted to the states for ratification, Delaware was the first of the thirteen original states to ratify the Constitution of the United States. This unanimous ratification took place in a convention of Dover on December 7, 1787, whereby Delaware became "The First State" of the new Federal Union. Proud of this heritage, Delawareans continue to honor the traditions which made them the First State to ratify the United States Constitution, the document that continues to protect our nation's justice, strength, and liberty.
