This is a broad timeline of the course of major events of the Syrian civil war. It only includes major territorial changes and attacks and does not include every event.
The Rojava–Islamist conflict, a major theater in the Syrian civil war, started after fighting erupted between the Kurdish People's Protection Units (YPG) and Islamist rebel factions in the city of Ras al-Ayn. Kurdish forces launched a campaign in an attempt to take control of the Islamist-controlled areas in the governorate of al-Hasakah and some parts of Raqqa and Aleppo governorates after al-Qaeda in Syria used those areas to attack the YPG. The Kurdish groups and their allies' goal was also to capture Kurdish areas from the Arab Islamist rebels and strengthen the autonomy of the region of Rojava. The Syrian Democratic Forces would go on to take substantial territory from Islamist groups, in particular the Islamic State (IS), provoking Turkish involvement in the Syrian Civil War.
Turkey's involvement in the Syrian civil war began diplomatically and later escalated militarily. Initially, Turkey condemned the Syrian government at the outbreak of civil unrest in Syria during the spring of 2011; the Turkish government's involvement gradually evolved into military assistance for the Free Syrian Army in July 2011, border clashes in 2012, and direct military interventions in 2016–17, in 2018, in 2019, 2020, and in 2022. The military operations have resulted in the Turkish occupation of northern Syria since August 2016.
The Battle of Sarrin refers to a military operation during 2015 in the northeastern Aleppo Governorate, during the Syrian Civil War, conducted by Kurdish YPG and allied forces against the Islamic State of Iraq and the Levant in the town of Sarrin, in an effort to capture the town and the surrounding region.
The Tell Abyad offensive or Martyr Rubar Qamışlo operation was a military operation that began in late May 2015 in the northern Raqqa Governorate, during the Syrian Civil War. It was conducted by the Kurdish-majority People's Protection Units (YPG) and the Free Syrian Army (FSA) against the Islamic State of Iraq and the Levant. The offensive took place from the end of May until July 2015. The campaign was the second phase of the Kurdish Operation Commander Rûbar Qamishlo, which began with the Al-Hasakah offensive, and involved the merger of the Kobanî offensive with the former. The focus of the campaign was to capture the key border town of Tell Abyad, and to link the Kobanî and Jazira Cantons in Northern Syria.
Ayn Issa is a town in the Tell Abyad District of Raqqa Governorate in Syria and a capital for the Autonomous Administration of North and East Syria. It is located halfway between the Syria–Turkey border town of Tell Abyad and the regional capital Raqqa. Through the city runs the M4 highway connecting Aleppo with the Hasakah Governorate.
The Syrian National Army, also known as the Turkish-backed Free Syrian Army (TFSA), is a coalition of armed Syrian opposition groups that participates in the Syrian civil war. Comprising various rebel factions that emerged at the start of the war in July 2011, it was officially established in 2017 under the auspices of Turkey, which provides funding, training, and military support.
Operation Olive Branch was an invasion of Syria conducted by the Turkish Armed Forces and Syrian National Army (SNA) in the majority-Kurdish Afrin District of northwest Syria, against the People's Protection Units (YPG) of the Syrian Democratic Forces (SDF). The air war and use of major artillery ended as the Arab and Turkmen militias of the SNA entered the city of Afrin on 18 March 2018, and the SDF insurgency in Northern Aleppo began.
The Afrin offensive was a military operation launched by the Turkish Armed Forces and the Turkish-backed Free Syrian Army against the Syrian Democratic Forces in Afrin District in northwestern Syria as the initial phase of Operation Olive Branch. At the end of military operations, the UN had registered 150,000 Kurdish refugees in camps in the area of Tel Rifaat; the Syrian Observatory for Human Rights (SOHR) estimated that 300,000 people had been expelled in total. By May, SOHR estimated that 40,000 settlers had been moved into Afrin, some of them Arabs displaced from eastern Ghouta, but mostly families of the mixed Arab and Syrian Turkmen militias.
The Idlib demilitarization was an agreement between Turkey and Russia to create a demilitarized zone (DMZ) in Syria's rebel-held Idlib Governorate, to be patrolled by military forces from Russia and Turkey. On 17 September 2018, the Russian president Vladimir Putin and Turkish president Recep Tayyip Erdoğan, reached an agreement to create a buffer zone in Idlib.
