The Yemeni Revolution followed the initial stages of the Tunisian Revolution and occurred simultaneously with the Egyptian Revolution and other mass protests in the Middle East in early 2011. In its early phase, protests in Yemen were initially against unemployment, economic conditions and corruption, as well as against the government's proposals to modify Yemen's constitution. The protestors' demands then escalated to calls for Yemeni President Ali Abdullah Saleh to resign. Mass defections from the military, as well as from Saleh's government, effectively rendered much of the country outside of the government's control, and protesters vowed to defy its authority. On 23 November, Saleh signed a power-transfer agreement brokered by the Gulf Cooperation Council in Riyadh, under which he would transfer his power to his Vice-President within 30 days and leave his post as president by February 2012, in exchange for immunity from prosecution. Although the GCC deal was accepted.
