Baron Godolphin is a title that was created three times: first in the Peerage of England, next in the Peerage of Great Britain, and then in the Peerage of the United Kingdom. The first creation, as Baron Godolphin, of Rialton in the County of Cornwall, was in the Peerage of England in September 1684 for Sidney Godolphin, a leading politician of the late seventeenth and early eighteenth centuries and former MP for Helston in Cornwall. In 1704 he was made a Knight of the Garter, and in December 1706 he was created Viscount Rialton and Earl of Godolphin. Upon his death in 1712, all these titles passed to his son Francis.
