The Yemeni Revolution (intifada), also known as the Yemeni Revolution of Dignity followed the initial stages of the Tunisian Revolution and occurred simultaneously with the Egyptian Revolution of 2011 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.

A major demonstration of over 16,000 protesters took place in Sanaa, Yemen's capital, on 27 January. On 2 February, Saleh announced he would not run for reelection in 2013 and that he would not pass power to his son. On 3 February, 20,000 people protested against the government in Sanaa, while others protested in Aden, a southern Yemeni seaport city, in a "Day of Rage" called for by Tawakel Karman, while soldiers, armed members of the General People's Congress and many protesters held a pro-government rally in Sanaa. In a "Friday of Anger" on 18 February, tens of thousands of Yemenis took part in anti-government demonstrations in Taiz, Sanaa and Aden. On a "Friday of No Return" on 11 March, protesters called for Saleh's ousting in Sanaa where three people were killed. More protests were held in other cities, including Mukalla, where one person was killed. On 18 March, protesters in Sanaa were fired upon, resulting in 52 deaths and ultimately culminating in mass defections and resignations.Starting in late April, Saleh agreed to a Gulf Cooperation Council-brokered deal, only to back away hours before the scheduled signing three times. After the third time, on 22 May, the GCC declared it was suspending its efforts to mediate in Yemen. On 23 May, a day after Saleh refused to sign the transition agreement, Sheikh Sadiq al-Ahmar, the head of the Hashid tribal federation, one of the most powerful tribes in the country, declared support for the opposition and his armed supporters came into conflict with loyalist security forces in the capital Sanaa. Heavy street fighting ensued, which included artillery and mortar shelling. Saleh and several others were injured and at least five people were killed by a 3 June bombing of the presidential compound when an explosion ripped through a mosque used by high-level government officials for prayer services. Reports conflicted as to whether the attack was caused by shelling or a planted bomb. The next day, Vice President Abdrabbuh Mansur Hadi took over as acting president while Saleh flew to Saudi Arabia to be treated. The crowds celebrated Saleh's transfer of power, but Yemeni officials insisted that Saleh's absence was temporary and he would soon return to Yemen to resume his duties of office.In early July the government rejected the opposition's demands, including the formation of a transitional council with the goal of formally transferring power from the current administration to a caretaker government intended to oversee Yemen's first-ever democratic elections. In response, factions of the opposition announced the formation of their own 17-member transitional council on 16 July, though the Joint Meeting Parties that have functioned as an umbrella for many of the Yemeni opposition groups during the uprising said the council did not represent them and did not match their "plan" for the country.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, Abdrabbuh Mansur Hadi, within 30 days and leave his post as president by February 2012, in exchange for immunity from prosecution. Although the GCC deal was accepted by the JMP, it was rejected by many of the protesters and the Houthis. A presidential election was held in Yemen on 21 February 2012, with Hadi running unopposed. A report claims that the election had a 65% turnout, with Hadi receiving 99.8% of the vote. Hadi took the oath of office in Yemen's parliament on 25 February 2012. Saleh returned home on the same day to attend Hadi's inauguration. After months of protests, Saleh had resigned from the presidency and formally transferred power to his successor, marking the end of his 33-year rule.

The Arab Spring (Arabic: الربيع العربي) was a series of anti-government protests, uprisings, and armed rebellions that spread across much of the Arab world in the early 2010s. It began in response to corruption and economic stagnation and was first started in Tunisia. From Tunisia, the protests then spread to five other countries: Libya, Egypt, Yemen, Syria, and Bahrain, where either the ruler was deposed (Zine El Abidine Ben Ali, Muammar Gaddafi, Hosni Mubarak, and Ali Abdullah Saleh) or major uprisings and social violence occurred including riots, civil wars, or insurgencies. Sustained street demonstrations took place in Morocco, Iraq, Algeria, Iranian Khuzestan, Lebanon, Jordan, Kuwait, Oman, and Sudan. Minor protests took place in Djibouti, Mauritania, Palestine, Saudi Arabia, and the Moroccan-occupied Western Sahara. A major slogan of the demonstrators in the Arab world is ash-shaʻb yurīd isqāṭ an-niẓām! ("the people want to bring down the regime").The importance of external factors versus internal factors to the protests' spread and success is contested. Social media is one way governments try to inhibit protests. In many countries, governments shut down certain sites or blocked Internet service entirely, especially in the times preceding a major rally. Governments also accused content creators of unrelated crimes or shutting down communication on specific sites or groups, such as Facebook. In the news, social media has been heralded as the driving force behind the swift spread of revolution throughout the world, as new protests appear in response to success stories shared from those taking place in other countries.

The wave of initial revolutions and protests faded by mid-2012, as many Arab Spring demonstrations were met with violent responses from authorities, as well as from pro-government militias, counter-demonstrators, and militaries. These attacks were answered with violence from protesters in some cases. Large-scale conflicts resulted: the Syrian Civil War; the rise of ISIL, insurgency in Iraq and the following civil war; the Egyptian Crisis, coup, and subsequent unrest and insurgency; the Libyan Civil War; and the Yemeni Crisis and following civil war. Regimes that lacked major oil wealth and hereditary succession arrangements were more likely to undergo regime change.A power struggle continued after the immediate response to the Arab Spring. While leadership changed and regimes were held accountable, power vacuums opened across the Arab world. Ultimately, it resulted in a contentious battle between a consolidation of power by religious elites and the growing support for democracy in many Muslim-majority states. The early hopes that these popular movements would end corruption, increase political participation, and bring about greater economic equity quickly collapsed in the wake of the counter-revolutionary moves by foreign state actors in Yemen, the regional and international military interventions in Bahrain and Yemen, and the destructive civil wars in Syria, Iraq, Libya, and Yemen.Some have referred to the succeeding and still ongoing conflicts as the Arab Winter. As of May 2018, only the uprising in Tunisia has resulted in a transition to constitutional democratic governance. Recent uprisings in Sudan and Algeria show that the conditions that started the Arab Spring have not faded and political movements against authoritarianism and exploitation are still occurring. In 2019, multiple uprisings and protest movements in Algeria, Sudan, Iraq, Lebanon, and Egypt have been seen as a continuation of the Arab Spring.As of 2021, multiple conflicts are still continuing that might be seen as a result of the Arab Spring. The Syrian Civil War has caused massive political instability and economic hardship in Syria, with the Syrian pound plunging to new lows. In Libya, a major civil war recently concluded, with Western powers and Russia sending in proxy fighters. In Yemen, a civil war continues to affect the country. In Lebanon, a major banking crisis is threatening the country's economy as well as that of neighboring Syria.
