The March of loyalty to martyrs (Arabic: masra al-waf ash-shuhad) was a protest on 22 February 2011 in Manama, Bahrain. Tens of thousands participated in the protest, one of the largest in the Bahraini uprising. Named after the seven victims killed by police and army forces during previous protests, the march filled the space between Bahrain mall and Pearl Roundabout. Protesters carried Bahrain's flag and demanded the fall of the government, implementation of a constitutional monarchy and other reforms, with some of them also demanding the end of the regime.

The march was named the largest in the country's history by organizers; sources estimated that over 100,000 protesters (a fifth of Bahraini citizens) participated, although other sources gave higher and lower estimations. A number of ambulance drivers, police and army officers joined the protest. Security forces were not present and unlike previous protests, it ended peacefully.

The 2011 Bahraini uprising was a series of anti-government protests in Bahrain led by the Shia-dominant and some Sunni minority Bahraini opposition from 2011 until 2014. The protests were inspired by the unrest of the 2011 Arab Spring and protests in Tunisia and Egypt and escalated to daily clashes after the Bahraini government repressed the revolt with the support of the Gulf Cooperation Council and Peninsula Shield Force. The Bahraini protests were a series of demonstrations, amounting to a sustained campaign of non-violent civil disobedience and some violent resistance in the Persian Gulf country of Bahrain. As part of the revolutionary wave of protests in the Middle East and North Africa following the self-immolation of Mohamed Bouazizi in Tunisia, the Bahraini protests were initially aimed at achieving greater political freedom and equality for the 70% Shia population.This expanded to a call to end the monarchy of Hamad bin Isa Al Khalifa following a deadly night raid on 17 February 2011 against protesters at the Pearl Roundabout in the capital Manama, known locally as Bloody Thursday. Protesters in Manama camped for days at the Pearl Roundabout, which became the centre of the protests. After a month, the government of Bahrain requested troops and police aid from the Gulf Cooperation Council. On 14 March, 1,000 troops from Saudi Arabia and 500 troops from UAE entered Bahrain and crushed the uprising. A day later, King Hamad declared martial law and a three-month state of emergency. Pearl Roundabout was cleared of protesters and the iconic statue at its center was demolished.Occasional demonstrations have continued since. After the state of emergency was lifted on 1 June 2011, the opposition party, Al Wefaq National Islamic Society, organized several weekly protests usually attended by tens of thousands. On 9 March 2012, over 100,000 attended and another on 31 August attracted tens of thousands. Daily smaller-scale protests and clashes continued, mostly outside Manama's business districts. By April 2012, more than 80 had died. The police response was described as a "brutal" crackdown on "peaceful and unarmed" protesters, including doctors and bloggers. The police carried out midnight house raids in Shia neighbourhoods, beatings at checkpoints and denial of medical care in a campaign of intimidation. More than 2,929 people have been arrested, and at least five died due to torture in police custody.: 287–8 In early July 2013, Bahraini activists called for major rallies on 14 August under the title Bahrain Tamarod.
