Statehood: 7 December 1787. In 1610, Samuel Argoll discovered a cape near the entrance of a large bay and named it after Thomas West, Lord de la Warr, first colonial governor of Virginia. The name soon was written "Delaware" and was transferred to a bay, river, and later the colony of settlements west of the bay.
