June 3. On this date in 1955, Shoghi Effendi addressed a cablegram titled "Archbreaker of Bahá'u'lláh's Covenant" announcing the death of Mirza Majdi'd-Din, the grandson of Bahá'u'lláh's only full brother Mírzá Músá and Bahá'u'lláh's scribe, by a stroke as "miserably perished struck with paralysis affecting his limbs and tongue" at the age of 100. Mirza Majdi'd-Din had supported Mírzá Muhammad `Alí.

Majdi'd-Dín was the son of Bahá’u’lláh's full brother Áqáy-i-Kalím, also known as Mirzá Musa, who is pictured here.  Majdi'd-Dín was married to Samadiyyih, Bahá’u’lláh's daughter from his second wife Fatimih Khanum, who Bahá’u’lláh titled Mahd-i-'Ulya. Both Majdi'd-Dín and Samadiyyih were eventually declared Covenant-breakers.

Mirza Majdi'd-Din for a time transcribed the Tablets of Bahá'u'lláh, but later became "the most redoubtable adversary of 'Abdu'l-Bahá" by supporting Mírzá Muhammad `Alí, the arch-breaker of the Covenant. Mirza Majdi'd-Din was the one who read the Kitáb-i-'Ahd in front of the family upon the death of Bahá'u'lláh.

Archbreaker of Bahá'u'lláh's Covenant
Announce to National Assemblies that Majdi'd-Din, the most redoubtable adversary of 'Abdu'l-Bahá, denounced by Him as the incarnation of Satan and who played a predominant part in kindling the hostility of `Abdu'l-Hamid and Jamál Páshá, and who was the chief instigator of Covenant-breaking and archbreaker of Bahá'u'lláh's Covenant, and who above sixty years labored with fiendish ingenuity and guile to undermine its foundations, miserably perished struck with paralysis affecting his limbs and tongue. Dispensation of Providence prolonged the span of his infamous life to a hundred years, enabling him to witness the extinction of his cherished hopes and the disintegration with dramatic rapidity of the infernal crew he unceasingly incited and zealously directed, and the triumphant progress and glorious termination of 'Abdu'l-Bahá's thirty-year ministry as well as evidences of the rise and establishment in all continents of the globe of the administrative order, child of the divinely-appointed Covenant and harbinger of the world-encircling order.
