    Islah anchors the 2011 uprising and the GCC transition that ousted Saleh

    Islah was the principal organized force behind the 2011 popular uprising against Ali Abdullah Saleh — its tribal and Brotherhood networks and the defection of General Ali Mohsen al-Ahmar gave the protests their backbone. As the lead bloc in the opposition JMP, Islah backed the GCC-brokered transition initiative Saleh signed on 23 November 2011 and took ministries in the subsequent unity government under President Hadi.

  • Confirmed Party formed September 13, 1990

    Islah founded in newly unified Yemen

    The Yemeni Congregation for Reform (al-Islah) was founded on 13 September 1990 in Sana'a — months after Yemeni unification — by tribal paramount sheikh Abdullah al-Ahmar together with Muslim Brotherhood figures and the Salafi scholar Abdul Majeed al-Zindani, with the tacit blessing of President Ali Abdullah Saleh. It fused a tribal confederacy, the Yemeni Muslim Brotherhood and a Salafi current into the country's main Sunni Islamist party.
