Persian Constitutional Revolution

Several fedayi and ARF key figures such as Aram Manukian, Hamo Ohanjanyan and Stepan Stepanian agreed upon joining the ongoing Iranian Constitutional Revolution in neighboring Qajar Persia.^[3]

They established that the movement was one that had political, ideological and economic components and was thus aimed at establishing law and order, human rights and the interests of all working people. They also felt that it would work for the benefit and interest of Armenian-Iranians. The final vote was 25 votes in favour and one absentia.^[3]

World War I

Some fedayi groups joined the Ottoman army after the Ottoman government passed a new law to support the war effort that required all enabled adult males up to the age of 45 to either be recruited in the Ottoman army or to pay special fees (which would be used in the war effort) to be excluded from service. As a result of this law, most able-bodied men were removed from their homes, leaving only the women, children, and elderly by themselves. Most of the Armenian recruits were later turned into road laborers, out of which many were executed.^[when?]

The Genocide, committed during World War I by the Ottoman Empire, gave way to the return of the fedayis, who reorganised themselves once again inside the borders of the Ottoman Empire. In turn, tens of thousands of Armenians volunteered to be drafted in several different armies. These Armenian volunteer units were formed inside the Russian army to fight against the Ottoman Empire.^[4]

The Russian Caucasus Front collapsed following the abdication of the Tsar. In 1917, the Armenian Congress of Eastern Armenians asked the Armenian soldiers and officers scattered throughout Russian occupied regions to gradually be brought together.^[5] The plan was to mobilize Armenians on the Caucasian front. With that purpose in view, an Armenian Military Committee was formed with General Bagradouni as its president.^[5] That year, the Armenian National Congress created the Armenian National Council, which established the First Republic of Armenia. These Armenian conscripts and volunteers from the Russian Army later established the core of the armed forces of the First Republic of Armenia. Armenian refugees from the Ottoman Empire were flooding the newly formed Armenian state. Further southeast, in Van, the fedayis helped the local Armenians resist the Turkish army until April 1918, but eventually were forced to evacuate and withdraw to Persia.

To consider emergency measures, the Western Armenian Administration sponsored a conference which adopted plans to form a 20,000-man militia under Andranik in December 1917. Civilian commissioner Dr. Hakob Zavriev promoted Andranik to Major General and he took the command of Armenia within the Ottoman Empire. They fought in numerous successful battles such as the Battle of Kara Killisse, the Battle of Bash Abaran and the Battle of Sardarapat, as fedayees merged with the Armenian army (Yerevan centered) under the General Tovmas Nazarbekian.

The total number of guerrillas in these irregular bands was 40,000–50,000, according to Boghos Nubar, the president of the Armenian National Delegation in the Paris Peace Conference of 1919, who wrote:

In the Caucasus, where, without mentioning the 150,000 Armenians in the Imperial Russian Army, more than 40,000 of their volunteers helped to liberate part of the Armenian vilayets, and where, under the command of their leaders, Antranik and Nazerbekoff, they alone, among the peoples of the Caucasus, offered resistance to the Turkish armies, from the beginning of the Bolshevist withdrawal right up to the signing of an armistice."^[6]

Boghos Nubar, as part of the Armenian Delegation, intended to expand the independent First Republic of Armenia. Thus, he might have elevated the number of Armenian fedayees who were able to fight in order to show that the Armenians are capable of defending an eventually large Ottoman-Armenian border. In reality, their numbers at that time were much lower, considering that there were no more than a few handful of fedayees in most of the confrontations between them and Kurdish irregulars or Turkish soldiers, even according to foreign accounts. Moreover, many of the fedayees were the same and reappeared in various places and battles. One should also note that many Armenian irregular fighters died defending regions of Western Armenia during the Armenian genocide.
