In Iran, the Hujjatiyya Society was started by Shaykh Mahmúd Halabí to persecute and harass the Bahá'ís. [S1296]
• During the Pahlaví era it confined itself to this end and was called the Anti-Bahá'í Society. [SI296]

The Hojjatiyeh movement initially presented itself as a conservative Islamic group that aimed to combat the spread of the Bahá'í Faith and defend the principles of Twelver Shia Islam. It considered the Bahá'í teachings to be a heretical deviation from Islam and saw Bahá'ís as apostates. The movement was critical of the Shah's regime and initially aligned itself with Ayatollah Ruhollah Khomeini, who led the Iranian Revolution in 1979. After the revolution, the Hojjatiyeh movement's activities and ideology began to be viewed with suspicion. Its radical and confrontational approach towards other religious minorities and even other Shia Muslims drew criticism from other clerics and political factions within the new government. In response to mounting pressure and criticism, Ayatollah Khomeini ordered the dissolution of the Hojjatiyeh society in 1983, effectively banning the organization. The movement's radical and divisive teachings were seen as a threat to the stability and unity of the newly established Islamic Republic.
