The title was first held by Odo, Count of Champagne created Earl of Holderness (an area of land occupying the far east of East Yorkshire along the North Sea and Humber Estuary) by his brother-in-law William the Conqueror after the Norman Conquest.
Odo was stripped of his English lands after being implicated in a plot to put his own son Stephen of Aumale upon the throne of England in place of his first cousin, William II.
[1] The second creation, in 1644, was as a subsidiary title of the Dukedom of Cumberland conferred on Prince Rupert of the Rhine, a nephew of King Charles I.
In 1641, his father, Sir Conyers Darcy, had successfully petitioned King Charles I to be restored to the abeyant baronies of Darcy de Knayth (created 1332) and Conyers (created 1509), with remainder to his heirs male.
(The 1641 decision was reversed in 1903, however, and both baronies were restored to the original remainders, which could be inherited by daughters.
