the passing of `Abdu'l-Bahá in 1921, the leadership of the Bahá'í
community entered a new phase, evolving from that of a single individual to
an administrative order founded on the "twin pillars" of the
Guardianship and the Universal House of Justice.
This administrative order was originally envisaged by Bahá'u'lláh in his Book
of Laws and was given further shape by `Abdu'l-Bahá, particularly in His Will
and Testament. In that document He appointed His eldest grandson, Shoghi
Effendi, as Guardian of the Bahá'í Faith and also referred to the future
election of the Universal House of Justice, a legislative body of which the
Guardian would be the "sacred head and the distinguished member for life."
