The Day of the Covenant is a Bahá'í holy day honouring the Covenant of Bahá'u'lláh, in particular, 'Abdu'l-Bahá as the "Centre of the Covenant" and as such, the successor, the interpreter and the exemplar of the Bahá'í Faith. Bahá'u'lláh's Covenant also provided for the extension of this covenant to the Guardian and to the Universal House of Justice.
The first celebration of the Day of the Covenant in North America was marked on this day in Chicago. It was sponsored by "The Chicago House of Justice" and the "Women's Assembly of Teaching". It was attended by both Mírzá Assad'ullah and Mírzá Abu'l-Fadl. It can be presumed that they had educated the community in the commemoration of this Holy Day. [BFA2p56-57]

Only days after the election of the Chicago House of Justice, a Ladies' Auxilliary Board was organized at the suggestion of Mrs. Ella Nash and Mrs. Corinne True. This Board was later to be known as the Women's Assembly of Teaching. It appears that the Ladies' Auxilliary was able to maintain control of the funds of the Chicago Bahá'í community despite the election of the House of Justice.[The Service of Women on the Institutions of the Baha'i Faith]

For several centuries the West has been now attacking the East like bandits with its armies and cavalries and has not stopped yet. And it is going to continue this assault with all troops at its disposal until Doomsday. You observe the large armies impetuously assaulting like lions from the woods of the Western world onto the battlefields of the East. Among these are an army of finance (tharwa), an army of industries (saná`a), an army of commerce (tijára), an army of politics (siyása), an army of knowledge (ma´árif) and an army of discoveries (iktisháfát), numerous soldiers loaded with war materiel, assaulting from the West with their sharp and deadly weapons and conquering the East in all its parts.
