Overview
The People's Defense Units, commonly abbreviated as YPG and also translated as the People's Protection Units, are a Syrian Kurdish-led armed organization associated with the autonomous administration in northern and eastern Syria. The organization emerged during the early stages of the Syrian civil war and became the dominant Kurdish military force in areas commonly associated with Rojava. Although its membership has historically been predominantly Kurdish, the YPG has also recruited Arabs and foreign volunteers and has operated alongside Assyrian and other local formations. The YPG's immediate institutional origins lie in self-defense committees created in Kurdish areas during 2011. Kurdish political forces, including the Democratic Union Party and the Kurdish National Council, participated in the political framework that established the Kurdish Supreme Committee. The committee helped organize the People's Defense Units to protect Kurdish-populated towns and enclaves as the Syrian state lost control of parts of the north. By 2012, the YPG had taken control of several important Kurdish areas, including Kobanî, Amuda, and Afrin, after Syrian government forces withdrew or reached local arrangements with Kurdish authorities. The organization initially concentrated on territorial defense and generally avoided direct confrontation with Syrian government forces. Its role changed as Islamist and jihadist groups, including the al-Nusra Front and the Islamic State, attacked Kurdish-held areas. The YPG's fighting in Ras al-Ayn and elsewhere helped it consolidate its position among Syrian Kurdish communities. Its most internationally consequential battle was the defense of Kobanî from the Islamic State in 2014 and early 2015. United States-led coalition air support and cooperation with local anti-Islamic State forces contributed to the YPG's eventual victory. That battle established the group as a significant ground partner for the coalition, while also provoking strong opposition from Turkey because of the YPG's perceived links to the Kurdistan Workers' Party. In October 2015, the YPG became the core military component of the Syrian Democratic Forces, an umbrella organization intended to bring Kurdish, Arab, Assyrian, and other local forces into a single anti-Islamic State framework. Under the SDF structure, forces associated with the YPG participated in campaigns that captured territory from the Islamic State, including al-Hawl, the Tishrin Dam, al-Shaddadi, Manbij, and ultimately Raqqa, the Islamic State's principal Syrian stronghold. The YPG's related Women's Protection Units, or YPJ, constitute a prominent female fighting formation operating alongside it. The YPG has also fought or clashed with Syrian rebel factions and Turkish forces. Turkey regards the organization as a terrorist entity because of its alleged organizational relationship with the PKK, a position not uniformly shared by the United States-led coalition or other international actors cooperating with the SDF against the Islamic State. Turkish military operations in Afrin in 2018 and northeastern Syria in 2019 reduced or disrupted YPG-controlled territory. The organization has been described by supporters as a self-organized people's defense force based on local autonomy, gender participation, and libertarian-socialist principles; critics have accused it and its associated administration of authoritarian practices, forced displacement, and links to the PKK. The YPG is not a conventional consumer brand or commercial enterprise. Its public identity is expressed through military insignia, flags, political messaging, affiliated media, and official communications rather than products or retail offerings. Its present institutional status is difficult to characterize separately from that of the SDF and the autonomous administration. Reference material states that, in early 2026, the SDF was being incorporated into the Syrian Army and that YPG commander Sipan Hamo was appointed deputy defense minister for eastern territories; the longer-term status of the YPG as a distinct organization therefore remains uncertain.
History
The People's Defense Units developed from Kurdish self-protection committees formed in northern Syria during 2011, as the Syrian civil war weakened government control and increased insecurity in Kurdish-populated districts. Kurdish activists had sought greater political and communal coordination for years, including after the 2004 Qamishli unrest, but the organization did not become a substantial military force until the civil war created a direct need for territorial defense. In July and August 2011, self-protection units known as YXG provided an organizational precursor to the YPG. The Kurdish Supreme Committee, associated with the Democratic Union Party and the Kurdish National Council, helped establish the YPG as a militia responsible for defending Kurdish areas. In 2012, Syrian government forces withdrew from or reached arrangements concerning several Kurdish-majority locations. The YPG subsequently took control of Kobanî, Amuda, and Afrin, and expanded its organization into brigades based in places including Qamishlo, Ras al-Ayn, al-Malikiyah, and al-Bab. The force initially followed a defensive policy and generally avoided opening a separate war with Damascus. That policy changed as armed Islamist groups challenged Kurdish-held territory. The YPG fought the al-Nusra Front and Ghuraba al-Sham in and around Ras al-Ayn, with the conflict ending in a YPG victory in 2013. Fighting with jihadist and Salafist groups helped the YPG become the leading Kurdish armed formation in Syria. It also brought the organization into increasingly complex relationships with Arab rebel groups, the Free Syrian Army, the Syriac Military Council, and other local forces. In October 2013, YPG fighters captured the border town and crossing of al-Yaarubiyah, also known as Til Koçer, creating a route toward areas of Iraq under the authority of the Iraqi central government. During 2014, the YPG fought alongside selected Free Syrian Army factions against the Islamic State and participated in joint coordination structures such as the Euphrates Volcano operations room. The Islamic State's attack on Kobanî in September 2014 transformed the YPG's international profile. The United States and other members of the coalition against the Islamic State provided substantial air support while the YPG and allied forces defended the city. The battle ended in early 2015 with an Islamic State defeat. The cooperation made the YPG a valued local partner for the coalition, but it also sharpened Turkish objections based on the organization's alleged links to the PKK. In 2015, YPG-led operations moved beyond purely defensive warfare. The capture of Tell Abyad connected Kobanî with the Hasakah area and interrupted a major Islamic State supply corridor. The YPG subsequently became the principal military component of the Syrian Democratic Forces, created in Hasakah on 11 October 2015. The SDF was designed as a broader Kurdish, Arab, and Assyrian coalition rather than an exclusively Kurdish force. Its early campaigns captured al-Hawl and the Tishrin Dam, followed in 2016 by operations around al-Shaddadi and Manbij and the opening of campaigns directed toward Raqqa and other Islamic State positions. The SDF campaign culminated in the capture of Raqqa, the Islamic State's de facto Syrian capital, after prolonged operations supported by the United States-led coalition. YPG and YPJ units also participated in fighting in other parts of northern Syria. The Women's Protection Units, established as a related female formation in 2012, became one of the most visible elements of the wider Kurdish-led military structure. The YPG's territorial gains generated conflict with Turkey and with several Syrian rebel groups. Turkey's 2018 intervention in Afrin removed the YPG from that region. A further Turkish offensive in northeastern Syria in 2019 produced additional territorial changes and prompted international debate over the relationship between Turkey's security claims, the YPG's PKK links, and the group's role in defeating the Islamic State. Turkey and Qatar have characterized the YPG as a terrorist organization, while that designation is not uniformly applied by the international states and institutions that cooperated with the SDF against the Islamic State. The organization's military method has generally emphasized mobile infantry, local knowledge, rapid redeployment, ambushes, snipers, improvised explosives, and decentralized decision-making. It has had less armor and heavy equipment than some rival Syrian factions, compensating through captured vehicles, repaired equipment, improvised armored platforms, and coalition assistance. The YPG has also supervised or trained local defense formations, including Yazidi units in the Sinjar area. Its political and military identity has been associated with libertarian-socialist ideas, communal defense, and gender participation, although critics have challenged the conduct and governance of YPG-linked authorities. Reference material reports a major institutional development in early 2026: incorporation of the SDF into the Syrian Army under Syria's transitional government. It further states that Sipan Hamo, identified as a YPG commander, became deputy defense minister for eastern territories. Because the durability and exact terms of that reported integration are not established in the supplied material, the YPG's current separate status is recorded as unknown.
