The Royal Stuart Society considers itself a successor to, and effectively the continuation of, bodies of the Neo-Jacobite Revival, such as the Legitimist Jacobite League of Great Britain and Ireland (founded in 1891 by Herbert Vivian, Ruaraidh Erskine and Melville Henry Massue), the Order of the White Rose and the Thames Valley Legitimist Club.

A service to commemorate the execution of Charles I of England is held at his statue in Trafalgar Square on 30 January each year, and a wreath is laid on the King's tomb at St George's Chapel, Windsor, at the beginning of Choral Evensong.

The nativity of King James VII and II of Scotland and England is marked by prayers and the laying of flowers at his statue outside the National Gallery on 14 October.

Lectures take place at the parish hall of the Jesuit church at Farm Street in London's Mayfair.

The Society publishes the Royal Stuart Journal annually, which replaces a series of publications called Royal Stuart Papers, which included papers by a number of well known historians, such as Roy Porter, Richard Sharpe, Murray Pittock, Eveline Cruickshanks, Lady Antonia Fraser, and Ronald Hutton.
