Yemen’s uprising began on Jan. 27, 2011, when thousands protested in Sanaa demanding economic reforms.

After months of unrest, Saleh agreed to hand power to his deputy, Abd Rabbuh Mansour al Hadi, on Nov. 23, 2011. Al Islah – a major Islamist party active in politics since the 1990s – negotiated Saleh’s exit along with the secular General People’s Council.
