Explanation is in illumination. To understand why the regime of Bashar al-Assad fell so suddenly in Syria in the past week, just note how night-time lights faded in cities it controlled.
Lighting is an indicator of prosperity, and in the years before the collapse it progressively dimmed in the regime’s cities and brightened in those controlled by the opposition. The opposition governed better, so its people were better off and could afford to turn on the lights.
A population shift is further evidence of the economic imbalance that helps explain the opposition’s success, alongside the important factor of loss of foreign air support.
After five years of relative stagnation, the battle lines in Syria saw seismic shifts, upending the entire history of the revolution and war. Within two weeks of a surprise offensive, Damascus had fallen, Bashar al-Assad had fled, and Russian bases along the country’s Mediterranean coast were hurriedly withdrawing. Over 20,000 days of continuous Assad totalitarian rule came crashing down in barely more than 10.

The groups mounting this offensive would hardly have considered this level of success. The offensive was initially launched to push back regime lines from civilian areas, where a concerted and systematic campaign of attacks on civilians by artillery and drones had created an unbearable burden of violence on many of the frontline communities. Instead, the regime retreated and didn’t stop. The 12 million Syrians who had been displaced from their homes by violence and fighting are now welcome to return home.
The crucial question is why and how did the regime’s lines collapse so quickly? Why was its command and control so poor? Why did it cede so much territory, captured during more than a decade and at the cost of tens of thousands of soldiers’ lives, to opposition forces within days without a fight?

One crucial element is a distinct lack of support by foreign backers—Russia, Iran and Hezbollah—each of which was embroiled in its own fight and unable to offer the high level of support that proved critical to the regime over the previous 10 years. Another element has been establishment of good governance by the Syrian Salvation Government and the Islamist Hayat Tahrir al-Sham (HTS), which maintains firm control over much of this area. Here, establishment of a responsive, civilian-led technocratic government has allowed for material improvements in the lives of civilians living in opposition-controlled areas. This is especially prominent following broad ceasefires that froze the front lines in Syria since 2020 and gave space for civilian institutions to re-emerge and grow despite regular attacks by regime forces.
That allowed the military factions of the opposition to rapidly professionalise, consolidate command structures and make major strides in developing new tactics and weapons (the role of drones and night-vision in the first week of this offensive was crucial in preventing Assad’s forces from regrouping and mounting counterattacks).
Those two factors explain why the regime lacked the overwhelming firepower it was once able to bring to the battlefield with allies’ help; they also explain how the opposition could seize the initiative and continue to push beyond their initial goals. However, they don’t address one critical issue that has proven decisive in battles since the offensive began: Why was the regime so unwilling to fight?

Detailed analysis of satellite imagery captured over the past decade begins to answer this question. Areas under regime control, despite the massive burden on loyalist communities to re-establish government control over much of Syria, have languished economically over the past six years. Demographic effects of more than a decade of war and the disproportionate degree of manpower coming from traditionally loyalist and Alawite communities have sucked opportunity from those areas. Widespread economic mismanagement and lingering effects of aggressive sanctions have forced the economy in regime areas to contract.
In short, for loyalist communities around Syria, 14 years of deep sacrifice and burden has only resulted in their communities going backwards. As HTS and allied militias began to shatter the thin veil of stability and security built up over the previous five years when the battle lines had been largely frozen, loyalist communities decided that the sacrifice was no longer worthwhile—especially in maintaining firm control over the large, Sunni-majority regions of Syria. The implicit social contract in which loyalist sacrifices were rewarded with patronage and preferential development had languished and then shattered under the pressure of an armed assault.
Urban illumination is widely considered to be a proxy for economic activity. Since 2018, the level of night-time illumination in major regime-controlled cities across Syria has roughly halved whereas key towns in opposition-controlled territory have increased their night-time lights by a factor of 10. This demonstrates that, despite an unending campaign of aerial bombing and economic pressure, opposition-controlled territories, since around 2018, were able to begin to reverse the years of acute destruction and see meaningful reconstruction and revitalisation.
Meanwhile, regime-controlled communities followed a different path. Reconstruction was essentially non-existent, neighbourhoods that revolted were demolished rather than rebuilt, and even loyalist communities saw drastic reductions in livelihoods and economic opportunities.
Syrian Democratic Forces (SDF) territory grew at a similar rate to opposition areas following the defeat of ISIS before stagnating under Turkish airstrikes, which systematically targeted power infrastructure.

The contrast is also clear in population estimates. The percentage of Syrians in Syria living in opposition-governed territory grew between 2020 and 2023, according to analysis by the Jusoor Center for Studies, from 24 percent to 26 percent, despite systematic bombardment and violence by the Assad regime.
Likewise, the effects of economic mismanagement and sanctions in government-controlled Syrian territory are clear in shortages of basic goods over the past four years, sweeping cutting of government subsidies and dramatic devaluation of the Syrian pound. For example, since 2020 there have been acute fuel shortages across government-held territory, which have worsened in recent months. Over that same period, the value of the Syrian pound has fallen from 2000 per US dollar to less than 15,000 per US dollar. The price of bread and other staple goods has drastically risen. Meanwhile, key figures within the regime were living lavishly: the Washington Post writes that, in recent years, they ran the country as their own ‘personal piggy bank’.
The battlefield effects of those dynamics were clear as soon as this shock offensive was launched. Frontline units melted away; for example, the fortified but undermanned 46th Regiment headquarters fell to opposition fighters in the first day of the offensive. As early as 28 November, there were widespread reports of soldiers from the loyalist coastal communities deserting the Aleppo, Idlib and Hama front lines to go home.
As the opposition offensive swept through Aleppo and kept pushing south, fighters came up against the Hama ‘minority-wall’. This is a collection of Christian and Alawite villages in Hama and Homs that had previously been mobilised by the Syrian Army to effectively defend the front lines in that area from opposition assaults. While some of those villages—with help from Syrian Army reinforcements—fiercely defended particular localities to the north of Hama, most of the villages were captured without fighting and often with local agreements. Such agreements saw the non-violent capture of both the Ismaili city of Salamiyah and the Christian town of Muhrahda on the outskirts of Hama by the opposition. That experience contrasts sharply with previous attempts at opposition outreach in those areas. It demonstrates both the increased local confidence in opposition governance and the languishing conditions in regime territory—not to mention the changing reality of the war. This has now occurred even in Assad’s home town.
In the days following the fall of Assad’s government, there was an outpouring of grievances and complaints about the final years of his rule, even from outright regime cheerleaders, who now felt comfortable discussing deep problems of Assad’s rule. Bashar al-Assad’s sister-in-law posted a picture of the revolutionary Syrian flag on Instagram.
While the rest of the world saw Syria as a frozen conflict, Assad and his regime’s poor governance were hollowing out state capacity and institutions and building resentment, and the lives of its people were only getting materially worse. Under the threat of a competent and concerted opposition offensive and without the support of foreign militaries to help the regime fight back more easily, Syrians pushed through that shell and emerged under a revolutionary flag.
