Ali Abdullah Saleh
Ali Abdullah Saleh unified northern and southern Yemen in 1990, maintaining power until the Arab Spring hit the country in February 2011. The November 2011 GCC Initiative transitioned power from Saleh to then Vice President and now current President Abdu Rabbu Mansour Hadi. Saleh joined forces with the al Houthi movement in 2014 in a power move to reclaim the Yemeni capital Sana'a, despite having fought six wars with the al Houthi movement during his presidency. Al Houthi forces killed Saleh in December 2017 after Saleh turned his back on the al Houthi movement.
