August 1887
The Cipher Manuscripts are discovered
Following the deaths of occult scholars Frederick Hockley and Kenneth Mackenzie, a set of papers written in encrypted code passed through the Reverend Woodford to Dr. William Wynn Westcott, Secretary of the Societas Rosicruciana in Anglia. These came to be called the Cipher Manuscripts.
October 1887
The Manuscripts are decoded
Westcott found the key — a simple letter-for-letter substitution from Abbot Trithemius's Polygraphiae — and decoded the papers into plain English written right-to-left. Once revealed, the manuscripts outlined initiatory rituals and graded lessons in astrology, alchemy, geomancy, Qabalah, Tarot and Hermetics. Westcott then engaged Mathers to flesh out the curriculum, and brought in Dr. William Robert Woodman as the third co-founder.
November 1887
Contact with Fraulein Sprengel
Among the Manuscripts was an encrypted address for a Rosicrucian Adept, Fraulein Sprengel of Nuremberg. Westcott corresponded with her; she granted the 7=4 grade to the founders and authorized the establishment of a Temple in England.
March 1, 1888
Isis-Urania Temple No. 3 is chartered
The warrant of the Temple of Isis-Urania was issued, with Mathers as Praemonstrator, Westcott as Cancellarius, and Woodman as Imperator. The first initiate was Mina Bergson, taking the motto Vestigia Nulla Retrorsum. The Golden Dawn as we know it was born.
1889
Mina Bergson advanced to Adept; further Temples established
Mina Bergson was advanced to the nominal grade of 5=6 Adeptus Minor. Osiris Temple No. 4 at Weston-Super-Mare and Horus Temple No. 5 at Bradford were both established. Mathers and Mina Bergson were married by Reverend Ayton.
July 1890
Continental ties are broken
Westcott received a letter reporting that Fraulein Sprengel had died, and that the Continental Adepts would withdraw correspondence. The Order was now without its authorizing body.
Summer 1891
Mathers contacts Continental Adepts in Paris
Mathers traveled to Paris and reported establishing contact with Continental Adepts in the Bois de Boulogne, including Frater Lux E Tenebris. He received a new set of Cipher Manuscripts in French, which laid out the Second Order.
December 1891
The R.R. et A.C. is established; Dr. Woodman dies
From the French manuscripts, Mathers established the inner Second Order, the Rosae Rubeae et Aureae Crucis. Annie Horniman became its first initiate into the full 5=6 grade. That same month, Dr. Woodman died suddenly, leaving no named successor within the Golden Dawn.
1893–1897
The Order at its height; notable members initiated
Florence Farr and W. B. Yeats were initiated into the Inner Order. The Matherses moved to Paris. The Order numbered among its members some of the most prominent artists, poets, and intellectuals of the Victorian era.
1900
The Revolt; Aleister Crowley and the crisis
Internal tensions over Mathers' autocratic leadership, his sending of Aleister Crowley to enforce his authority in London, and the authenticity of the Secret Chiefs led to the formal split of the Order. The majority of the Isis-Urania members voted to depose Mathers. The unified Golden Dawn as originally constituted effectively ended.
1900–1920
Successor orders and factions
Multiple successor orders emerged from the ruins: the Independent and Rectified Rite under Yeats, the Stella Matutina under Robert Felkin, A.E. Waite's Independent and Rectified Rite, and eventually Dion Fortune's Society of the Inner Light. Mathers continued to lead the Alpha et Omega in Paris until his death in 1918.
1937–1940
Israel Regardie publishes the complete system
Israel Regardie, who had served as Aleister Crowley's secretary and later joined Stella Matutina, published The Golden Dawn in four volumes, revealing the Order's complete curriculum to the public. This act, though controversial, preserved the tradition.
1977–present
Modern revival
Chic Cicero founded a new Golden Dawn lodge in the United States in 1977. He and Tabatha Cicero later received the blessing of Israel Regardie, who consecrated the Vault of the Adepti before his death in 1985. The Hermetic Order of the Golden Dawn, Inc. continues this lineage today.
