The Pilgrims Society, an aristocratic Anglo-American dining club, was established over a century ago and meets at least two or three times a year. Its membership consists of the most influential bankers, lawyers, insurance brokers, and businessmen from the New York and London areas. A handful of career politicians also come from Washington.

The club's primary purpose is to keep the ties between the United States and Britain as close as possible.

The London chapter of the Pilgrims Society was established on July 11, 1902, followed by a New York chapter on January 13, 1903. Its patron is the British monarch, who has plenty of representatives attending the meetings. A member of the Royal family usually attends the London diners.

The Pilgrims Society has clearly fused together the business centers of New York and London, together with a large portion of the political centers of both nations. Ninety percent of the American members are top-level bankers and businessmen from New York city.
