The Peshmerga (Kurdish: پێشمەرگه, romanized: Pêşmerge, lit. ''Those Who Face Death'') are the internal security forces of Kurdistan Region. According to the Constitution of Iraq, regional governments are responsible for "the establishment and organization of the internal security forces for the region such as police, security forces, and guards of the region". Other Kurdish security agencies include the Zêrevanî (gendarmerie), Asayish (security and counterterrorism service), and the Parastin u Zanyarî (intelligence agency). The Peshmerga's history dates back to the 18th century, when they began as a tribal paramilitary border guard under the Ottoman Turks and the Safavid Kurds. By the 19th century, they had evolved into a disciplined and well-trained guerrilla force.
Formally, the Peshmerga are under the command of the Ministry of Peshmerga Affairs (MoPA) of the Kurdistan Regional Government (KRG). In practice, however, the Peshmerga's structure is largely divided and controlled separately by the two Iraqi Kurdish political parties: the Democratic Party of Kurdistan (KDP) and the Patriotic Union of Kurdistan (PUK). Unifying and integrating the Peshmerga under the MoPA has been on the Kurdistan Region's public agenda since 1992, with significant progress under a 2022 U.S.-KRG Memorandum of Understanding (MoU) aiming for full unification by 2026, though challenges like partisanship and external threats persist.
