Overview

A conflict that began as a popular uprising in 2011 and became a multifaceted civil war leaving more than half a million dead and half the population displaced. The fall of Bashar al-Assad in December 2024, after the lightning offensive led by Hayat Tahrir al-Sham, opened an unprecedented transition: the government of Ahmed al-Sharaa, formalized in March 2025, seeks to reunify a country fragmented between the new central power, the Kurdish-led northeast of the SDF — integrating under the January 2026 agreement — the Druze south of Suweida, and pockets of old-regime loyalist insurgency and ISIS.

The transition combines progress (accelerated sanctions relief, the return of more than 3 million displaced people and refugees, partial SDF integration) with severe fragilities: sectarian violence against Alawites and Druze, incomplete transitional justice, a humanitarian funding collapse and Israel's occupation of positions south of Damascus. The result as of mid-2026 is a state under reconstruction, still lacking a monopoly on force or consolidated national reconciliation.

The transitional government of Ahmed al-Sharaa, formalized on 29 March 2025, continues to consolidate institutionally but remains fragile. On 9 May 2026 al-Sharaa reshuffled key posts (the presidency's secretary-general and the information and agriculture ministries) following criticism over nepotism, and on 24 May 2026 by-elections were held in formerly Kurdish-controlled areas to fill 11 vacant People's Assembly seats. On transitional justice, the Interior Ministry confirmed the arrest of nearly 6,000 former Assad regime members, while early-June 2026 protests demanding accountability in some cases escalated into mob violence against minorities and individuals linked to the former regime. ISIS remains an acute threat: it claimed multiple attacks in June 2026 in Aleppo, Raqqa and rural Damascus, and a three-month government counter-terrorism campaign ended with 235 operatives arrested.

Humanitarian impact

The humanitarian crisis is not a byproduct — it is a central feature of the conflict.

Actor map

Who faces whom.

Every actor with what they control and what they are after, and the ties of support and hostility that bind them to the rest. The camps are not assigned by hand: they come from the alliances and enmities recorded in the profile.

History4 milestones

Timeline — Key phases

The conflict as process. Each event: context, actors and consequences.

2011-2012 — 2020-2024

  1. Peaceful protests escalate to armed rebellion against Assad regime

    Arab Spring Uprising & Military Crackdown

    Syrian Arab Spring protests begin in Daraa, demanding democratic reforms. Assad regime responds with military force, torture, arbitrary detention. Hundreds killed in initial crackdowns. Defections from military increase; armed opposition coalesces into Free Syrian Army (FSA). Conflict quickly transitions from civil protest to armed insurgency.

    Actors: Assad government forces, FSA, civil society, protesters Consequences: Militarization of uprising; thousands displaced; sectarian tensions rise; international attention intensifies; formation of various opposition groups

  2. US, Russia, Iran, Saudi Arabia, Turkey all deploy military assets; chemical weapons use

    Internationalization & Proxy War Escalation

    Assad regime begins chemical weapons attacks; August 2013 Ghouta chemical attack kills 1,000+, nearly triggers US military intervention. Russia and Iran dramatically increase military support to Assad. Saudi Arabia, Turkey, US support various opposition groups (many becoming radicalized). ISIS emerges as major actor in Syria, capturing territory. Conflict becomes geopolitical battleground for regional and global powers.

    Actors: Assad regime, multiple opposition groups, ISIS, Russia, Iran, US, Saudi Arabia, Turkey, various proxies Consequences: Massive international military presence; opposition fragmentation; humanitarian catastrophe accelerates; millions become displaced; sectarian violence intensifies

  3. Russian airstrikes turn tide toward Assad; opposition fragmentation deepens

    Russian Intervention & Assad Regime Consolidation

    September 2015 Russian military intervention with airstrikes dramatically escalates Assad's military advantage. Combined with Iranian ground forces and Hezbollah fighters, Assad forces recapture major cities and territory. Opposition becomes increasingly fragmented; many groups destroyed or co-opted. Humanitarian situation deteriorates catastrophically. US-backed Kurdish forces (SDF) control northeast; Turkish military operations target Kurdish positions.

    Actors: Assad regime, Russia, Iran, Hezbollah, opposition remnants, US-backed SDF, Turkey, ISIS Consequences: Assad military advantage becomes overwhelming; stalemate in some regions; opposition collapse accelerates; humanitarian crisis reaches epic proportions; 5+ million refugees

  4. Arab League readmission followed by unexpected rapid regime collapse

    Assad Regime Normalization & December 2024 Collapse

    2020-2023: Assad regime gradually normalized regionally; Arab League readmission in May 2023 despite ongoing crimes. International community accepts Assad's survival. However, December 2024 sees shocking rapid collapse of Assad regime as opposition forces launch offensive. HTS-led forces capture Aleppo, Damascus; Assad flees to Russia. Entire military structure collapses. Transition government led by HTS begins assuming control. Post-Assad Syria uncertain; international concern about HTS Islamist governance; reconstruction and accountability questions paramount.

    Actors: HTS, SNA, Assad regime (collapsed), opposition forces, Turkey, Russia, Iran, US, Syria transition government Consequences: Complete regime collapse; leadership flight; military dissolution; international uncertainty; transition government establishes authority; accountability mechanisms needed; reconstruction planning begins
Monitoring indicators

Concrete signals the editorial team monitors to anticipate phase changes.

  • SDF integration

    Improving

    Four brigades already integrated; the hard points (Asayish, YPJ, curriculum) will gauge whether the January deal consolidates.

  • Suweida roadmap

    Stable

    'No progress' per the UN a year after the massacre; the Druze south remains the transition's most fragile flank.

  • ISIS attack tempo

    Stable

    Claimed attacks in Aleppo, Raqqa and rural Damascus; gauges the new state's counter-terrorism capacity.

  • Humanitarian and bread funding

    Worsening

    2026 appeal 20% funded and the bread subsidy terminated: the aid collapse could destabilize returns.

Open conflict · as of Jul 22, 2026

An open conflict we analyse but do not follow day to day. This profile gathers the context, actors and sources verified up to the cut-off date, and publishes no severity index: we do not add new events or recalculate the CSI unless the conflict escalates and we reactivate it. We say so plainly so you know what you are reading.

We publish how complete each profile is. These are the points of our editorial policy that can be checked against the data on file.

Sources & methodology

Syrian data sourced from Syrian Observatory for Human Rights, OCHA, UNHCR, ICG reports, and academic conflict analysis. Death figures (617,000) reflect documentation since March 2011. Current displacement numbers reflect post-regime-collapse crisis.

Key sources

Assad regime's shocking December 2024 collapse marks a crucial inflection point in Syrian history. Thirteen years of civil war have left a devastated country with millions displaced and collapsed infrastructure. Post-Assad transition success will depend on HTS's inclusive governance, international reconstruction support, and regional willingness to respect Syrian sovereignty.
