In the same March 5, 1922 letter to the Baháʼís of the world that called for the election of local Spiritual Assemblies, Shoghi Effendi called on them to “indirectly” elect National Spiritual Assemblies. He also enumerated committees that a National Spiritual Assembly should have in order to carry out its responsibilities. “Indirect” election referred to the process, mentioned in the Will and Testament of ʻAbdu'l-Bahá, of the Baháʼís electing one or more delegates from each locality, who would represent them at a national convention and would vote for the nine members of the National Spiritual Assembly. The 1928 issue of "The Baháʼí World" listed nine National Spiritual Assemblies: Persia (Iran); the United States and Canada; Germany; Great Britain and Ireland; India and Burma; Egypt; Turkistan; Caucasus; and Iraq. Of these, the Iranian body was still the “Central Spiritual Assembly” in Tehran, elected by the Baháʼís of that community; it was not until 1934 that a national Baháʼí membership list could be drawn up that allowed the election of delegates and convening of a fully representative national convention. It is possible that the Turkistan and Caucasus bodies were preliminary as well. By 1953 the number of National Spiritual Assemblies worldwide had increased to 12; in 1963, 56; by 1968, 81, by 1988, 148; by 2001, 182.
