The Treaty of Zuhab (Qasr-e Shirin), signed on May 17, 1639, between the Ottoman Empire (Sultan Murad IV) and the Safavid Empire (Shah Safi), stands as one of the most critical and influential geopolitical treaties in the history of the Middle East. This treaty brought an end to a 150-year war between these two powers over the control of Mesopotamia (Iraq) and Kurdistan.
The concept of the "Buffer Logic" represents a profound strategic and political interpretation of the consequences of this treaty, particularly concerning the fate of the Kurdish nation. Below is a detailed explanation of both concepts:
1. What is the Treaty of Zuhab?
Prior to 1639, the region was engulfed in a state of perpetual conflict; Baghdad and its surrounding areas frequently changed hands between the Sunni Ottomans and the Shia Safavids. The Treaty of Zuhab was established to forge permanent stability through a demarcated border. According to this treaty:
- Present-day Iraq (Baghdad, Basra, and Sharazor) fell entirely under Ottoman control.
- The regions of Azerbaijan and Yerevan in the Caucasus remained under Safavid rule.
- The Zagros mountain range was designated as the official and natural border between the two empires.
- This border, drawn in 1639, continues to serve as the foundational basis for the modern borders between Iraq and Iran, as well as Turkey and Iran.
2. What is the "Buffer Logic"?
In geopolitical science, a "buffer zone" refers to a geographical area situated between two major, rival powers, serving to prevent direct confrontation and war between them. When discussing the "Buffer Logic of the Treaty of Zuhab" in relation to Kurdistan, it encompasses the following dimensions:
- Kurdistan as a Human and Geographical Shield: Both empires came to the realization that they could not entirely annihilate one another. Consequently, they utilized the territory of Kurdistan (which houses the Zagros mountain range) as a "natural barrier" to separate themselves. Kurdistan became the shock absorber for the waves of attacks from both sides, ensuring that their respective capitals (Istanbul and Isfahan) remained unharmed.
- The First Official Division: This border demarcation resulted in the formal and legal division of the Kurdish geography into two primary spheres (Ottoman Kurdistan and Safavid Kurdistan). This fracture effectively hindered the unified cultural and economic development of the Kurdish nation.
- The Sphere of "Divide and Conquer": The buffer logic dictates that the inhabitants of the buffer zone (in this case, the Kurds) must remain in a perpetual state of weakness, unable to emerge as an independent, unified force. If the Kurds were to become a formidable power, the balance between the Ottomans and Safavids would be disrupted. Therefore, both empires actively worked to sow discord among the Kurdish emirates, often pitting one emirate against another.
Conclusion: Repercussions and Reflections in Modern History
The importance of understanding the "Zuhab Buffer Logic" lies in the fact that it forms the foundation of the political philosophy adopted by regional states toward the Kurds. When the Sykes-Picot Agreement (1916) and the Treaty of Lausanne (1923) divided Kurdistan among four modern states in the 20th century, they were essentially renewing and expanding the "Zuhab Buffer Logic" onto the maps of modern nation-states.
Even today, when regional and global powers utilize the Kurdish issue as a "pressure card" or as a protective proxy force (for instance, in the war against terrorism or for maintaining regional balance), it is a direct continuation of the same logic engineered nearly 400 years ago at Zuhab: maintaining a geography as a barrier and an instrument to protect the interests of others, rather than recognizing it as an independent legal actor.
