Because efforts to organize local Baháʼí consultative bodies remained informal, few additional ones had formed by 1921 (notable exceptions being Cleveland, Ohio, and London), and some of the ones in the United States had lapsed. Upon assuming the Guardianship of the Baháʼí Faith, Shoghi Effendi read ʻAbdu'l-Bahá's Will and Testament and made establishment of local spiritual assemblies an early priority. His second general letter to the Baháʼís of the world, dated March 5, 1922, referred to the “vital necessity of having a local Spiritual Assembly in every locality where the number of adult declared believers exceeds nine.” The letter also quoted extensively from Baháʼu'lláh and ʻAbdu'l-Bahá about the purposes and duties of Spiritual Assemblies.
