Religion in Algeria
The Bahá'í Faith in Algeria dates from 1952. Though the religion achieved some growth and organization through 1967 including converts, the period of the independence of Algeria when the country adopted Islamic practices in rejection of colonial influences and subsequently the religion was effectively banned in 1968. However more recently the Association of Religion Data Archives and Wolfram Alpha estimated the population of Bahá'ís at 3.3–3.8 thousand Bahá'ís in 2005 and 2010.
