PhasesHigh confidence
Phase I
For four centuries "Syria" was a geography, not a state: Ottoman provinces centred on Damascus and Aleppo, tied into trade routes running from Anatolia to the Hejaz and the Mediterranean to the Euphrates.
Phase II
The post-war settlement gave France a League of Nations mandate over Syria and Lebanon.
Phase III
Independent Syria cycled through coups — the 1949 trio began an era in which the army made and unmade governments — a brief union with Egypt (1958–61), and the radicalisation of politics around land, Palestine and the Cold War.
Phase IV
Hafez al-Assad built the system Syria lived under until 2024: a presidency above a single party, overlapping security agencies watching each other and everyone else, an officer corps stacked with Alawite loyalists, and a foreign policy of disciplined ruthlessness — intervention in Lebanon from 1976, alliance with Iran from 1979, confrontation-and-negotiation with Israel over the Golan.
Phase V
Bashar al-Assad inherited the presidency in June 2000 — the constitution amended overnight to fit his age — and briefly raised reform hopes (the "Damascus Spring") before the apparatus closed them down.
Phase VI
The Arab uprisings reached Syria in March 2011, when the detention and torture of schoolboys who had written anti-regime graffiti in Daraa brought protests the security forces answered with gunfire.
Phase VII
Defectors announced a Free Syrian Army in July 2011; by mid-2012 Syria was in full civil war.
Phase VIII
The opposition fragmented as it grew — hundreds of brigades, Islamist coalitions eclipsing the FSA label, and al-Qaeda's Syrian branch (Jabhat al-Nusra, led by Ahmed al-Sharaa under the name Abu Mohammad al-Jolani) becoming one of the most capable rebel forces.
Phase IX
When the regime pulled back from the Kurdish north in 2012 to concentrate on the war, the PYD — the Syrian affiliate of the PKK's political family — and its YPG militia filled the space, declaring autonomous cantons in 2013–14.
Phase X
The regime survived on foreign force.
Phase XI
With Russian air power and Iranian-organised ground forces, the regime retook the rebellion's urban strongholds one siege at a time: eastern Aleppo fell in December 2016 after a bombardment that became the war's emblem, then Homs's remnants, Eastern Ghouta in 2018 under siege and chemical attack, and the south including Daraa — the uprising's birthplace — that summer.
Phase XII
Türkiye entered the ground war to shape its border, not to decide the capital.
Phase XIII
The SDF, with coalition air power and special forces, ground the caliphate out of its cities: Manbij, then Raqqa in October 2017 after a battle that destroyed much of the city, then the Euphrates valley towns, and finally Baghouz in March 2019, where the territorial caliphate ended.
Phase XIV
From 2020 the war froze along four zones — regime centre, Idlib under HTS (al-Sharaa's organisation, rebranded and locally entrenched), the Turkish north, the SDF northeast — held in place by the March 2020 Idlib ceasefire and exhaustion.
Phase XV
On 27 November 2024 HTS and allied factions attacked out of Idlib; Aleppo fell within days, and the army's collapse became a cascade — Hama, then Homs, then Damascus without a battle on 8 December, as Bashar al-Assad flew to Moscow.
Phase XVI
The transition moved fast and unevenly.
For four centuries "Syria" was a geography, not a state: Ottoman provinces centred on Damascus and Aleppo, tied into trade routes running from Anatolia to the Hejaz and the Mediterranean to the Euphrates. The late Ottoman decades layered the elements the twentieth century would fight over — communal coexistence organised under imperial rule rather than shared citizenship, Kurdish, Alawite, Druze and Christian communities with distinct regional concentrations, and an Arab urban notability whose politics awakened as the empire weakened. The First World War ended the arrangement: famine, conscription and repression radicalised the Arab provinces, and the empire's collapse left the region to be divided by others.
Syria's communal map predates Syria: the coastal, southern and northern concentrations that shaped the civil war — and shape the transition — were centuries old before the border existed.
The post-war settlement gave France a League of Nations mandate over Syria and Lebanon. French forces crushed the short-lived Arab Kingdom of Syria at Maysalun in July 1920, then governed by division — separate statelets for the Alawite coast and the Druze south, Lebanon detached, and the Turkish border drawn to leave Syria's Kurds a minority strip along a frontier that split communities. The Great Syrian Revolt of 1925–27 was suppressed at heavy cost; independence came in 1946 only after another world war and nationalist pressure. The Mandate bequeathed a state with borders nobody had chosen, minority regions with memories of separate status, and an army that recruited heavily from the margins — including the Alawite community that would later rule through it.
The Mandate built the fractures the war would open: minority regions with a memory of autonomy, a border that made the Kurds a divided periphery, and a military that became the ladder for communities the urban elite excluded.
Independent Syria cycled through coups — the 1949 trio began an era in which the army made and unmade governments — a brief union with Egypt (1958–61), and the radicalisation of politics around land, Palestine and the Cold War. The Baath Party seized power in March 1963 and purged its way to a narrower and narrower base; the 1967 war lost the Golan Heights to Israel and discredited the radicals; and in November 1970 Defence Minister Hafez al-Assad's "Corrective Movement" ended the instability by ending open politics altogether.
The Baath takeover fused party, army and security services into one apparatus — the machine the Assads would run for half a century, and the machine the transition now has to replace rather than merely inherit.
Hafez al-Assad built the system Syria lived under until 2024: a presidency above a single party, overlapping security agencies watching each other and everyone else, an officer corps stacked with Alawite loyalists, and a foreign policy of disciplined ruthlessness — intervention in Lebanon from 1976, alliance with Iran from 1979, confrontation-and-negotiation with Israel over the Golan. The Muslim Brotherhood's insurgency of 1979–82 was answered with the destruction of Hama in February 1982 — thousands to tens of thousands killed, the event that taught Syrians what the state would do — and a long peace of fear followed. The state was stable, and hollow: institutions existed to serve the presidency, not to survive it.
Hama 1982 is the war before the war: it set the regime's template — overwhelming violence as first resort against internal challenge — and the opposition's memory of it shaped 2011 on both sides.
Bashar al-Assad inherited the presidency in June 2000 — the constitution amended overnight to fit his age — and briefly raised reform hopes (the "Damascus Spring") before the apparatus closed them down. His decade combined selective economic liberalisation that enriched a connected crony class, drought and rural neglect that drove migration into peri-urban belts, the loss of Lebanon's occupation after the 2005 Hariri assassination, and a security state unreformed at its core. By 2010 Syria looked stable to visitors and brittle to its own margins — the towns and suburbs where 2011 would begin.
The uprising's geography was written in this decade: the neglected rural belts and provincial cities hit by drought and exclusion rose first, while the connected urban cores held longest.
The Arab uprisings reached Syria in March 2011, when the detention and torture of schoolboys who had written anti-regime graffiti in Daraa brought protests the security forces answered with gunfire. Demonstrations spread — Homs, Hama, the Damascus and Aleppo countrysides, the coast, the Kurdish northeast — through a summer of escalating crackdown: mass arrest, siege of protest cities, the army deployed against civilians. The political demands escalated with the violence, from reform to the fall of the regime. By late 2011 defecting soldiers were organising armed protection of protest areas, and the uprising's peaceful phase was ending — militarised by the state's answer to it.
The regime's first-resort violence converted a protest movement into a war — the founding causality of everything after, and the reason accountability remains the transition's hardest file.
Defectors announced a Free Syrian Army in July 2011; by mid-2012 Syria was in full civil war. The rebellion took the countryside and the poorer halves of the great cities — the battle for Aleppo began in July 2012 and split the city for four years — while the regime concentrated on the spine linking Damascus, Homs, Hama and the coast, and answered rebel gains with air power, artillery and sieges. Chemical weapons crossed from fear to fact with the Ghouta sarin attack of August 2013, which killed hundreds of civilians; the US-Russian deal that followed removed declared stockpiles and confirmed, to each side, what outside powers would and would not do. Sectarian logic hardened as both sides' worst actors gained.
The war settled into the pattern that decided it: the regime could not retake the country, the rebellion could not take the centre, and both outsourced the difference to foreign patrons — the internationalisation that would keep the war alive for a decade.
The opposition fragmented as it grew — hundreds of brigades, Islamist coalitions eclipsing the FSA label, and al-Qaeda's Syrian branch (Jabhat al-Nusra, led by Ahmed al-Sharaa under the name Abu Mohammad al-Jolani) becoming one of the most capable rebel forces. Its Iraqi parent then swallowed the stage: the Islamic State broke with al-Qaeda, took Raqqa from other rebels, seized Mosul in June 2014 and declared a caliphate spanning the Iraqi-Syrian border. ISIS fought the rebellion as much as the regime, and its atrocities — including the genocidal assault on the Yazidis and the threatened massacre of Kurdish Kobani — pulled the United States into the war by air that September.
ISIS changed the war's international meaning: from 2014 the outside world's Syria policy was counter-ISIS first, regime-change a distant second — a reordering that saved Assad strategically and created the US-Kurdish partnership that shaped the northeast for a decade.
When the regime pulled back from the Kurdish north in 2012 to concentrate on the war, the PYD — the Syrian affiliate of the PKK's political family — and its YPG militia filled the space, declaring autonomous cantons in 2013–14. The siege of Kobani in late 2014 made the YPG the coalition's ground partner of choice: with US air support it broke the ISIS assault in January 2015, and that October the Syrian Democratic Forces were formed — a YPG-led, Arab-inclusive umbrella built to take the caliphate down. Kurdish self-administration expanded with the campaign, governing by 2019 a third of Syria including its oil and grain — and inheriting the problems of governing Arab-majority areas with a Kurdish-led force, under a Turkish state that saw the whole project as the PKK by another name.
The northeast question of 2025–26 was built here: a decade of de facto autonomy, earned in the anti-ISIS war, run by structures Türkiye treats as terrorists — an equation no integration agreement can solve on paper alone.
The regime survived on foreign force. Hezbollah's open entry at Qusayr in 2013 and Iran's construction of a militia network — Iraqi, Afghan and Pakistani fighters under IRGC coordination — stabilised the army's manpower crisis and built Tehran a position in Syria that outgrew the war: bases, transit to Lebanon, and a corridor from Iraq. When even that was not enough — by mid-2015 the regime was visibly losing — Russia intervened directly from September 2015 with an air campaign that reversed the war's direction. Moscow's price was permanence: the Khmeimim air base and an expanded Tartus naval facility on 49-year terms, and the status of indispensable broker in every diplomatic format that followed.
Two rescues created two dependencies — and both bills came due in 2024, when neither patron would or could pay again. The bases and networks they left are the transition's inherited foreign-policy file.
With Russian air power and Iranian-organised ground forces, the regime retook the rebellion's urban strongholds one siege at a time: eastern Aleppo fell in December 2016 after a bombardment that became the war's emblem, then Homs's remnants, Eastern Ghouta in 2018 under siege and chemical attack, and the south including Daraa — the uprising's birthplace — that summer. The method was consistent: encirclement, starvation, bombardment, and "evacuation" of fighters and civilians to Idlib, which became the concentrated remainder of the rebellion. By late 2018 the regime controlled the cities and the map's centre — a victory that reconquered territory without recovering the state.
The reconquest produced a state that ruled rubble: military victory without political settlement, reconstruction or return — the hollow stability that collapsed in eleven days in 2024.
Türkiye entered the ground war to shape its border, not to decide the capital. Euphrates Shield (2016) cut ISIS from the border and blocked the YPG from linking its cantons; Olive Branch (2018) took Afrin from the YPG, displacing much of its Kurdish population; Peace Spring (2019), launched into the space left by a US pullback announcement, took a border strip between Tal Abyad and Ras al-Ayn — and pushed the SDF into its first security arrangement with Damascus and Moscow. Alongside the operations, Ankara organised the factions it backed into the Syrian National Army and built administration, currency and trade links into its zones — an influence infrastructure that outlived the war.
Türkiye's zones made it a party to Syria's territorial order — the only outside power holding ground with local governance attached. Its leverage over the transition, and over the northeast's terms, grows from this decade of accumulated position.
The SDF, with coalition air power and special forces, ground the caliphate out of its cities: Manbij, then Raqqa in October 2017 after a battle that destroyed much of the city, then the Euphrates valley towns, and finally Baghouz in March 2019, where the territorial caliphate ended. What remained was an insurgency — desert cells, assassination campaigns in Deir ez-Zor, and a detention archipelago: thousands of fighters in SDF-run prisons and tens of thousands of family members in al-Hol and Roj camps, a population the world declined to repatriate and the region could not absorb. ISIS's project shifted to survival, prison breaks and patience.
The caliphate's defeat created the northeast's twin inheritance: the SDF's international standing and the prisons and camps that made it indispensable — assets and liabilities the integration agreement now transfers to the state.
From 2020 the war froze along four zones — regime centre, Idlib under HTS (al-Sharaa's organisation, rebranded and locally entrenched), the Turkish north, the SDF northeast — held in place by the March 2020 Idlib ceasefire and exhaustion. What moved was the economy, downward: currency collapse, Lebanon's banking implosion, the Caesar Act sanctions from mid-2020, fuel and bread crises, and a state that ran on captagon exports and aid diversion. The February 2023 earthquakes killed thousands in the northwest; that May the Arab League readmitted Assad, betting normalisation would buy stability and refugee returns. It bought neither: by 2024 the regime was poorer, hollower and more isolated from its own base than at any point since 2011.
The frozen years disproved the "Assad won" consensus: the regime survived the war but not the peace — its economy, army and patronage rotted until a two-week offensive was enough.
On 27 November 2024 HTS and allied factions attacked out of Idlib; Aleppo fell within days, and the army's collapse became a cascade — Hama, then Homs, then Damascus without a battle on 8 December, as Bashar al-Assad flew to Moscow. Hezbollah was broken by its war with Israel; Russia was absorbed in Ukraine; Iran's networks declined to die for a client whose army would not fight. The 54-year Assad era ended in eleven days. Israel destroyed much of the former state's military assets by air within a week and moved into the Golan buffer zone; the region scrambled to meet the man it had listed as a terrorist — Ahmed al-Sharaa, whose forces now held the capital.
The fall vindicated no one's Syria policy: the patrons abandoned, the deterrents failed, and the "stability" normalisation had priced in evaporated in days. Every actor's 2025 position was improvised from that surprise.
The transition moved fast and unevenly. Al-Sharaa was named president in January 2025, HTS and the factions formally dissolved into new state structures, a constitutional declaration followed in March, and elections seated an appointed-and-elected interim parliament by mid-2026. Sanctions fell in stages — US relief from May 2025, the Caesar Act repealed that December. But March 2025 brought the coastal massacres of Alawite civilians — over 1,400 killed, with government-affiliated forces implicated by UN investigators — and July 2025 the Sweida violence and Israeli strikes on Damascus. The March 2025 SDF integration framework stalled, collapsed into fighting in January 2026, and was re-founded on harder terms by a US-brokered agreement on 30 January. The US withdrew fully by April 2026; Israel negotiates and strikes in parallel; Russia bargains for its bases; Sweida stands off. The transition is real, and so is every warning about it.
The transition's pattern is consistent: consolidation first, inclusion later, accountability last. Whether that order can be reversed — before it hardens into a new exclusionary state — is the module's central question.
