Arab Spring: After 11 months of protests in Yemen, Yemeni president Ali Abdullah Saleh signs a deal to transfer power to the vice president, in exchange for legal immunity.

The Arab Spring was a series of pro-democracy anti-government protests, uprisings, and armed rebellions that spread across much of the Arab world in the early 2010s. It began in Tunisia in response to corruption and economic stagnation. From Tunisia, the protests initially spread to five other countries: Libya, Egypt, Yemen, Syria and Bahrain. Rulers were deposed and major uprisings and social violence occurred, including riots, civil wars, or insurgencies. Sustained street demonstrations took place in Morocco, Iraq, Algeria, Lebanon, Jordan, Kuwait, Oman and Sudan. Minor protests took place in Djibouti, Mauritania, Palestine, Saudi Arabia and the Western Sahara. A major slogan of the demonstrators in the Arab world is ash-shaʻb yurīd isqāṭ an-niẓām!.

The Yemeni revolution followed the initial stages of the Tunisian revolution and occurred simultaneously with the 2011 Egyptian revolution and other Arab Spring protests in the Middle East and North Africa. 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 protesters' demands then escalated to calls for the resignation of Yemeni President Ali Abdullah Saleh. 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.

Ali Abdullah Saleh was a Yemeni military officer and politician who served as the first president of the Republic of Yemen from the Yemeni unification in 1990 until his resignation in 2012, following the Yemeni revolution. Previously, he had served as the fifth and last President of the Yemen Arab Republic, from July 1978 to 22 May 1990, after the assassination of President Ahmad al-Ghashmi. al-Ghashmi had earlier appointed Saleh as military governor in Taiz.
