Although the SUUE became a member of the International Council of Unitarians and Universalists (ICUU) in June 2001 and had fellowships, first in Barcelona (founded in 2000), and then also in Madrid (founded in 2003), it did not achieve recognition as a religious organization from the Spanish government.
