Wriothesley Russell, 2nd Duke of Bedford KG was an English nobleman and politician. He was the son of William Russell, Lord Russell, and his wife Lady Rachel Wriothesley. From 1683 until 1694, he was styled Lord Russell, and from 1695 until his accession in 1700, Marquess of Tavistock.

William Russell, Lord Russell was an English politician. He was a leading member of the Country Party, forerunners of the Whigs, who during the reign of King Charles II, laid the groundwork for opposition in the House of Commons to the accession of an openly Catholic king in Charles's brother James. This ultimately resulted in Russell's execution for treason, almost two years before Charles died and James acceded to the throne.
