Introduction
On 4 April 1946, Iranian Prime Minister Ahmad Qavam and Soviet Ambassador Ivan Sadchikov signed an oil agreement that would seal the fate of the Republic of Mahabad — the only independent Kurdish republic in modern history. The Qavam-Sadchikov Agreement established a joint Soviet-Iranian oil corporation (51% Soviet, 49% Iranian) for fifty years, covering the oil-bearing regions of northern Iran. In return, the Soviet Union agreed to withdraw the Red Army troops that had been occupying northern Iran since the Anglo-Soviet invasion of 1941.
For the Kurdish people, this agreement was a death sentence. The Soviet presence in northern Iran had been the shield that protected the Republic of Mahabad and allowed Kurdish self-governance to flourish for eleven extraordinary months. Once Soviet troops withdrew, there was nothing to prevent the Iranian army from marching into Kurdish territory. In December 1946, Iranian forces crushed the Republic of Mahabad. Its president, Qazi Muhammad, was hanged in Chwarchira Square on 31 March 1947. The Kurdish dream of independence — briefly, brilliantly realised — was extinguished by a deal between Moscow and Tehran over oil.

What Was the Qavam-Sadchikov Agreement?
The Qavam-Sadchikov Agreement was an oil concession deal signed on 4 April 1946 between Iranian Prime Minister Ahmad Qavam and Soviet Ambassador Ivan Sadchikov. It established a joint Soviet-Iranian oil corporation with a 51% Soviet and 49% Iranian shareholding for a period of fifty years, covering the petroleum-bearing regions of northern Iran (Iranian Azerbaijan). The agreement was the price Iran paid to secure the withdrawal of Soviet Red Army forces that had occupied northern Iran since the joint Anglo-Soviet invasion of August 1941.
The agreement was made under extreme duress. Soviet troops had refused to withdraw from Iran after World War II, in violation of Allied agreements. Soviet forces had sponsored two separatist entities in northern Iran: the Azerbaijan People’s Government under Ja’far Pishevari and the Republic of Mahabad under Qazi Muhammad. The Iran crisis of 1946 became one of the earliest confrontations of the Cold War, with the United States pressuring the Soviet Union through the newly created United Nations Security Council. Qavam’s strategy was to offer Stalin the oil concession to secure Soviet withdrawal — then revoke it once the troops were gone.
Key Takeaways
• The agreement secured Soviet withdrawal from Iran — removing the protective umbrella under which the Republic of Mahabad had been able to exist, and directly enabling its destruction.
• The Republic of Mahabad (January–December 1946) was the only independent Kurdish republic in modern history — a sovereign Kurdish state with its own flag, army, parliament, and president, Qazi Muhammad.
• The Iranian Majlis rejected the oil agreement in October 1947 by a vote of 102 to 2 — meaning Qavam’s concession was a masterful diplomatic bluff that secured Soviet withdrawal while never actually granting the oil rights.
• The Kurds were once again betrayed by a great power — the Soviet Union abandoned the Republic of Mahabad as a bargaining chip, trading Kurdish independence for an oil deal that was never even honoured.

Historical Context: The Republic of Mahabad and Soviet Occupation
In August 1941, Britain and the Soviet Union jointly invaded Iran to secure supply lines and prevent Nazi influence. Soviet forces occupied northern Iran, including Iranian Azerbaijan and the Kurdish regions around Mahabad. When the war ended in 1945, British and American forces withdrew as agreed. Soviet troops did not. Instead, the Soviet Union sponsored two separatist entities: the Azerbaijan People’s Government in Tabriz under Ja’far Pishevari, and the Republic of Mahabad in the Kurdish northwest under Qazi Muhammad.
The Republic of Mahabad was proclaimed on 22 January 1946. It was a remarkable achievement: a Kurdish state with its own government, parliament, army, flag, and national anthem (‘Ey Reqîb’ — ‘O Enemy!’ — which remains the unofficial Kurdish national anthem to this day). Qazi Muhammad served as president. Mustafa Barzani — the legendary Kurdish leader who had arrived from Iraq with 12,750 Peshmerga fighters — served as the republic’s military commander. Kurdish was used as the language of education and administration. For the first and only time in modern history, Kurds governed themselves in an internationally distinct Kurdish political entity.
But the republic’s existence depended entirely on Soviet protection. Soviet troops prevented the Iranian army from entering Kurdish and Azerbaijani territory. When Qavam negotiated the oil agreement and secured Soviet withdrawal, the republic was left exposed. The Soviet Union had used the Kurds as a bargaining chip — establishing the republic to pressure Iran, then abandoning it once a favourable deal was struck.
The Fall of the Republic of Mahabad
Soviet troops completed their withdrawal from Iran by May 1946. Through the spring and summer, the central government attempted to negotiate with the Azerbaijan and Kurdish autonomous governments, but no political settlement was reached. In December 1946, Qavam ordered the Iranian army into Azerbaijan and Kurdistan, ostensibly to restore order before new parliamentary elections. Without Soviet backing, both autonomous governments collapsed.
On 15 December 1946, Iranian forces reoccupied Mahabad. The Republic of Mahabad — which had existed for just eleven months — was destroyed. Pishevari fled to the Soviet Azerbaijan SSR. Qazi Muhammad chose to stay with his people. He was arrested, tried, and executed by hanging in Chwarchira Square in Mahabad on 31 March 1947, alongside his brother and cousin. His execution remains one of the most powerful symbols of Kurdish martyrdom.
Mustafa Barzani refused to surrender. He led his Peshmerga fighters on a legendary fighting retreat across the Iranian, Turkish, and Iraqi borders into the Soviet Union — one of the great military marches of the 20th century. Barzani would remain in Soviet exile for over a decade before returning to Iraq to lead the Kurdish independence struggle in the 1960s.

Legacy and Significance for Kurdish History
The Qavam-Sadchikov Agreement is devastating in Kurdish memory because it reveals, with brutal clarity, how great powers use Kurdish aspirations as bargaining chips. The Soviet Union did not support the Republic of Mahabad out of commitment to Kurdish self-determination. It supported Mahabad as a pressure tool against Iran — and abandoned it the moment a better deal was available. The Kurds were, once again, means to an end, not an end in themselves.
The Republic of Mahabad, despite its brief existence, holds an extraordinary place in Kurdish national consciousness. It proved that Kurdish self-governance was not just a dream but a practical reality. In eleven months, the republic established Kurdish-language education, created a functioning government, built an army, and demonstrated that Kurds were capable of governing themselves. Its national anthem, ‘Ey Reqîb,’ is still sung at Kurdish gatherings worldwide. Its flag inspires Kurdish movements across all four parts of Kurdistan.
The final irony is that the oil agreement itself was a fiction. The Iranian Majlis rejected it by an overwhelming vote in 1947, led by deputies including Mohammad Mosaddegh, who would later nationalise Iranian oil entirely. The Soviet Union got nothing. The Kurds lost everything. The Republic of Mahabad was destroyed for an oil deal that was never honoured — perhaps the most bitter illustration of the Kurdish proverb that the Kurds have no friends but the mountains.
