The rise of ISIS in Syria was not a sudden eruption of extremism, but a complex and insidious process rooted in the failures of the Syrian civil war and the subsequent power vacuum. While the initial uprising against Bashar al-Assad’s regime began with legitimate calls for democracy and freedom, the ensuing chaos and lack of effective governance created fertile ground for radical groups to exploit. The story of Manbij, a city in northern Syria, offers a stark illustration of how ISIS capitalized on local grievances and disillusionment, initially presenting itself as a provider of order amidst widespread instability. Understanding this trajectory is crucial to comprehending the enduring threat of extremist ideologies and the challenges of post-conflict stabilization.
The Syrian conflict, beginning in 2011, quickly devolved into a multi-sided war involving the Assad government, various rebel groups, and international actors. As the government struggled to maintain control, many cities and towns found themselves liberated from state authority, but often without a viable alternative. This period of liberation, while initially welcomed, quickly revealed the deep-seated problems plaguing Syrian society – economic hardship, rampant crime, and a lack of basic services. It was within this context of disillusionment that ISIS began to emerge as a potential, albeit dangerous, solution. The city of Manbij, near the Turkish border, became a focal point in this unfolding drama, demonstrating how a yearning for justice and security could be manipulated by extremist ideologies.
From Revolution to Chaos in Manbij
In 2012, Manbij was among the first Syrian cities to experience a shift in power, with citizens successfully driving out forces loyal to President Bashar al-Assad. The initial euphoria of liberation, though, soon gave way to a harsh reality. While dozens of newspapers and magazines sprang up, reflecting a newfound freedom of expression, the new city government, largely controlled by business owners and elites, struggled to address the needs of the population. As reported by The New Yorker, the price of essential goods like bread soared as bakery owners exploited the lack of price controls, and rents doubled or tripled due to the influx of displaced Syrians. This economic hardship was compounded by a surge in crime, leaving residents feeling increasingly vulnerable and questioning whether the revolution had truly improved their lives.
The breakdown of law and order created a climate of fear and desperation. Residents began to wonder if basic security and justice were worth more than abstract ideals of freedom and human rights. This sense of vulnerability and the perceived failure of the new authorities to provide for their needs created an opening for ISIS to exploit. The group initially presented itself not as a revolutionary force, but as a guarantor of order and justice, appealing to those who felt abandoned by the existing power structures. This strategy proved particularly effective in a city like Manbij, where the initial hopes of a democratic transition had been dashed by economic hardship and rampant criminality.
The Arrival of ISIS and the Pursuit of Justice
In June 2013, ISIS quietly established a presence in Manbij, opening an office and displaying its black banner proclaiming the fundamental tenet of Islam. While their initial intentions were unclear, the group began to subtly position itself as an alternative to the dysfunctional local government and the ineffective security forces. The catalyst for their more overt intervention came with the murder of Musa Jasim, a young man whose death exposed the deep-seated frustrations with the existing judicial system. According to reporting from The New Yorker, Musa’s family sought justice, but found the local authorities unresponsive and unable to provide a resolution.
Abdul Hadi Bisher, a local activist and member of the Revolutionary Youth Movement, played a pivotal role in this unfolding drama. Having previously been imprisoned and tortured for his pro-democracy activities, Bisher had become disillusioned with the post-Assad government in Manbij. He saw in Musa’s case an opportunity to challenge the status quo and demand accountability. He approached an ISIS commander, seeking intervention, but was initially told that the group could not interfere without the explicit demand of the people. This seemingly cautious response was, in fact, a calculated move by ISIS to gauge public support and legitimize their involvement.
Bisher organized a rally, gathering hundreds of residents who chanted for justice and demanded the swift punishment of those responsible for Musa’s death. The demonstration, initially peaceful, grew in size and intensity, with protesters directing their anger not only at the suspected murderers but also at the various Free Syrian Army factions who had failed to provide security. This display of public discontent provided ISIS with the pretext it needed to intervene. In a dramatic turn of events, ISIS members stormed the courthouse, disarmed the police, and took custody of the suspects, effectively bypassing the existing judicial system. This brazen act, while shocking, was met with cheers from the crowd, highlighting the extent of the public’s desperation for justice and order.
Exploiting the Vacuum: ISIS’s Consolidation of Power
The intervention in the Musa Jasim case proved to be a turning point for ISIS in Manbij. By presenting itself as a force capable of delivering justice and security, the group quickly gained the support of a significant portion of the population. This support was not necessarily ideological; rather, it was pragmatic, driven by a desire for stability and an conclude to the chaos that had plagued the city since the fall of Assad. As the BBC reported in 2019, Manbij had already experienced multiple shifts in control since the start of the Syrian civil war, first falling to rebel groups, then to ISIS, and finally to the Syrian Democratic Forces (SDF) backed by the US-led coalition. This constant cycle of conflict had left residents weary and longing for a lasting peace.
ISIS exploited this weariness by establishing a parallel system of governance, providing basic services, enforcing strict law and order, and offering economic opportunities to its supporters. While their methods were often brutal and their ideology deeply repressive, they were able to create a semblance of stability that had been absent for years. This success in Manbij served as a model for ISIS’s expansion throughout Syria and Iraq, demonstrating the effectiveness of their strategy of exploiting local grievances and presenting themselves as a viable alternative to the existing authorities. The group’s ability to capitalize on the failures of the post-Assad government and the broader international community proved to be a key factor in its rapid rise to prominence.
The Syrian Democratic Forces and the US Role
The situation in Manbij remained volatile for years, with the city becoming a focal point of contention between various regional and international actors. In 2016, the Syrian Democratic Forces (SDF), a US-backed alliance of Kurdish and Arab militias, captured Manbij from ISIS. This victory was a significant blow to the group, but it did not end the conflict in the city. The BBC noted that the presence of US troops in Manbij deterred a Turkish military offensive, as Ankara viewed the SDF, particularly the Kurdish YPG component, as an extension of the Kurdistan Workers’ Party (PKK), a designated terrorist organization.
However, the withdrawal of US forces announced by President Donald Trump in December 2018 created a new period of uncertainty for Manbij. The threat of a Turkish invasion loomed large, raising fears of renewed conflict and further displacement. A deal was brokered between the US and Turkey, leading to the withdrawal of SDF forces from Manbij and the deployment of Turkish-backed Syrian fighters. This complex series of events underscores the intricate geopolitical dynamics at play in Syria and the challenges of achieving a lasting peace.
The Legacy of Manbij: Lessons Learned
The story of Manbij serves as a cautionary tale about the dangers of state collapse, the importance of effective governance, and the insidious appeal of extremist ideologies. It demonstrates how a yearning for justice and security can be exploited by groups like ISIS to gain support and consolidate power. The initial failures of the post-Assad government to address the needs of the population created a vacuum that ISIS was able to fill, highlighting the critical role of providing basic services and upholding the rule of law in post-conflict environments.
The experience of Manbij also underscores the complexities of international intervention in Syria. While the US-led coalition played a crucial role in defeating ISIS, the subsequent withdrawal of troops created a new set of challenges and uncertainties. The ongoing geopolitical competition between regional and international actors continues to complicate the situation, making it tricky to achieve a lasting peace. The lessons learned from Manbij are relevant not only to Syria but also to other conflict-affected regions around the world, where the threat of extremism remains a significant concern.
As of February 2026, Manbij remains under the control of Turkish-backed forces, and the long-term stability of the region remains uncertain. Ongoing monitoring of the security situation and continued efforts to address the underlying grievances of the population are essential to prevent a resurgence of extremism. Further research into the dynamics of ISIS’s rise in Manbij and other Syrian cities is crucial to informing effective counter-terrorism strategies and promoting sustainable peace.
