The Invitation to William was a letter sent by seven notable English nobles, later called "the Immortal Seven", to stadtholder William III, Prince of Orange, received by him on 30 June 1688. In England, the heir apparent to the throne, James Francis Edward Stuart, had just been born to the unpopular King James II of England, and baptised a Catholic. The letter asked William, who was a nephew and son-in-law of James II, to use military intervention to force the king to make his eldest daughter, Mary, William's Protestant wife, his heir. The letter alleged that the newborn prince was an impostor. The letter informed William that if he were to land in England with a small army, the signatories and their allies would rise up and support him. The Invitation briefly rehashed the grievances against King James. It claimed that the king's son was supposititious and that the English people generally believed him to be so. The present consensus among historians is that he was almost certainly their real son. The letter deplored that William had sent a letter to James congratulating him for the birth of his son, and offered some brief strategy on the logistics of the proposed landing of troops. It was carried to William in The Hague by Rear AdmiralArthur Herbert disguised as a common sailor, and identified by a secret code. The invitation caused William to carry out his existing plans to land with a large Dutch army, culminating in the Glorious Revolution during which James was deposed and replaced by William and Mary as joint rulers. William and Mary had previously asked for such an invitation when William started to assemble an invasion force in April of that year. This request was done through secret correspondence that had been taking place since April 1687, between them and several leading English politicians, regarding how best to counter the pro-Catholic policies of James. William later justified his invasion by the fact that he was invited, which helped to disguise the military, cultural and political impact that the Dutch regime had on England at a time his reign was unpopular and he feared a popular uprising. The signatories were:
Danby and Compton were generally considered to be Tories, the other five as Whigs. After William's rise to power, five were elevated further in the peerage; Russell was made a peer with the mid-rank of Earl; and Compton as Bishop of London had his suspension, running into a third year, lifted and performed the Coronation, granted lands granted in Maryland to his second cousin, and became a commissioner in revision of the litany.
