The Grand Lodge of Iran, established in 1969 in Tehran, existed in the country prior to the Islamic Revolution of 1979. At its height, it counted 43 Lodges and at least 1,035 members.
Since the Revolution, Freemasonry has been banned in Iran; a “Grand Lodge of Iran in Exile” was created to provide a home for those Masons.
In March 1985, the Grand Lodge of Massachusetts voted to allow the exiled Grand Lodge to hold Masonic activities within their jurisdiction. Additional Lodges have been warranted in Washington D.C., France and in California all under the Persian Grand Lodge (in Exile).
